Accounting Policies [Abstract]
Summary of Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation — Interim Financial Statements Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These statements include all adjustments (consisting of normal recurring adjustments) management believes are necessary to fairly state the results of operations, comprehensive income, financial position, changes in shareholders' equity, and cash flows. The Company's management believes the disclosures are adequate to make the information presented not misleading when read in conjunction with the audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2018 , which was filed with the Securities and Exchange Commission on March 18, 2019. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The Company has previously announced its intentions to separate its businesses through a spinoff transaction in mid-2020 to form two new, independent publicly traded companies, an Aftermarket and Ride Performance company ("DRiV") and a new Powertrain Technology company ("New Tenneco"). Tenneco remains committed to the separation of the businesses and continues to execute its plan for the spinoff. Additionally, the company is evaluating multiple strategic options to deleverage and facilitate the separation. Certain of these options could help mitigate the effect of challenging market conditions, which, if current trends were to continue, would likely affect the company’s ability to complete a separation in the mid-year 2020 time range. In preparation for the separation, the Company began to manage and report its DRiV businesses through two new operating segments, in the first quarter of 2019, as compared to the three operating segments it had previously reported. The DRiV operating segments consist of Motorparts and Ride Performance. The new Motorparts operating segment consists of the previously reported Aftermarket operating segment as well as the aftermarket portion of the previously reported Motorparts operating segment. The Ride Performance operating segment consists of the previously reported Ride Performance operating segment as well as the OE Braking business that was included in the previously reported Motorparts operating segment. As such, prior period operating segment results and related disclosures have been conformed to reflect the Company's current operating segments. The future New Tenneco consists of two existing operating segments, Powertrain and Clean Air. See Note 17, Segment Information . Redeemable Noncontrolling Interests — The Company has noncontrolling interests with redemption features. These redemption features could require the Company to make an offer to purchase the noncontrolling interests at fair value in the event of a change in control of Tenneco Inc. or certain of its subsidiaries. The redemption of these redeemable noncontrolling interests is not solely within the Company's control. Accordingly, these noncontrolling interests are presented in the temporary equity section of the Company's condensed consolidated balance sheets. The Company does not believe it is probable the redemption features related to these noncontrolling interest securities will be triggered, as a change in control event is generally not probable until it occurs, except as discussed in Note 3, Acquisitions and Divestitures , for the redeemable noncontrolling interests from the Acquisitions. The following is a rollforward of activities in the Company's redeemable noncontrolling interests: Nine Months Ended September 30, 2019 2018 Balance at beginning of period $ 138 $ 42 Net income (loss) attributable to redeemable noncontrolling interests 19 22 Other comprehensive income (loss) (10 ) (3 ) Acquisition and other 17 — Purchase accounting measurement period adjustment (8 ) — Dividends declared (17 ) (33 ) Balance at end of period $ 139 $ 28 The Company recorded a decrease to the redeemable noncontrolling interests of $8 million from the Federal-Mogul Acquisition, as a result of adjustments made in the measurement period. The purchase price allocation for the Federal-Mogul Acquisition has been finalized. The purchase price allocation for the Öhlins Acquisition is preliminary and subject to finalization. The Company's current estimates and assumptions may change as a result. See Note 3, Acquisitions and Divestitures for additional information. Earnings (loss) per share — Basic earnings (loss) per share is calculated by dividing net earnings (loss) by the weighted average shares outstanding during the period. Diluted earnings (loss) per share reflects the weighted average effect of all potentially dilutive securities from the date of issuance. Actual weighted average shares outstanding used in calculating earnings (loss) per share were: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Weighted average shares of common stock outstanding 80,916,676 51,272,618 80,903,967 51,247,664 Effect of dilutive securities: Restricted stock, PSUs and RSUs — 93,956 — 95,022 Stock options — 35,255 — 53,241 Dilutive shares outstanding 80,916,676 51,401,829 80,903,967 51,395,927 For the three and nine months ended September 30, 2019 , the calculation of diluted earnings (loss) per share excluded 1,895,180 and 1,865,345 of share-based awards, as the effect on the calculation would have been anti-dilutive. For the three and nine months ended September 30, 2018 , the calculation of diluted earnings (loss) per share excluded 124,865 and 124,606 of share-based awards, as the effect on the calculation would have been anti-dilutive. Revision of Previously Issued Financial Statements The Company identified an error in the accounting for certain costs capitalized into inventory that did not constitute inventoriable costs in its historical financial statements. The Company also revised for other immaterial errors related to various line items. As a result, certain amounts in the condensed consolidated financial statements have been revised for the three and nine month periods ended September 30, 2018 . These revisions were not material to the previously issued financial statements and are presented in the tables below. In addition, during the three and nine months ended September 30, 2019 , the Company recorded an immaterial $5 million charge in its Ride Performance segment related to prior periods. Reclassifications: Certain amounts in the prior years have been aggregated or disaggregated to conform to current year presentation.

The amendments in this update allow a reclassification from accumulated other comprehensive income (loss) to accumulated deficit for stranded tax effects resulting from the Tax Cuts and Jobs Act ("TCJA"). The Company has elected not to adopt the optional reclassification. Leases — In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update supersedes the lease requirements in Topic 840, Leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted this update on January 1, 2019 using the modified retrospective method without the recasting of comparative periods’ financial information, as permitted by the transition guidance. The Company adopted the package of practical expedients that allows companies to not reassess its previous conclusions related to contracts that contain leases, existing lease classification, and initial direct costs, and to carry forward its historical conclusions. It elected the land easements practical expedient allowing the Company not to reassess whether existing or expired land easements not accounted for as leases under previous guidance are or contain leases under the new guidance. It also did not adopt the hindsight practical expedient and has also made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases will be expensed over the lease term. As a part of the implementation effort, the Company reviewed its internal control structure and modified and augmented existing controls, as necessary. The adoption of the new standard resulted in the recording of additional lease assets and lease liabilities of $387 million and $383 million , and a reduction of favorable lease intangibles of $4 million as of January 1, 2019. The standard did not materially affect the Company's condensed consolidated financial position or results of operations and had no effect on cash flows. See Note 14, Leases . Accounting Standards Issued But Not Yet Adopted Intangibles — In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for interim and annual periods for the Company beginning on January 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the potential effect of this new guidance on its financial statements. Retirement benefits — In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). The amendments in this update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The new standard (i) requires the removal of disclosures that are no longer considered cost beneficial; (ii) clarifies specific requirements of certain disclosures; and (iii) adds new disclosure requirements, including reasons for significant gains and losses related to changes in the benefit obligation. The amendments in this update are effective for fiscal years ending after December 15, 2020 with early adoption permitted. The Company is currently evaluating the potential effect of this new guidance on its financial statements and will include the enhanced disclosures in the consolidated financial statements upon adoption. Fair value measurements — In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company is currently evaluating the potential effect of this new guidance on its financial statements but does not expect this guidance to have a material effect on its consolidated financial statements.

Business Combinations [Abstract]
Acquisitions and Divestitures	3. Acquisitions and Divestitures The preliminary allocation of the purchase price of the assets acquired and liabilities assumed, including the residual amount recognized as goodwill, is based upon estimated information and is subject to change within the measurement period. The measurement period is a period not to exceed one year from the acquisition date during which the Company may adjust estimated or provisional amounts recorded during purchase accounting if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities as of that date. Any adjustments to amounts recorded in purchase accounting that do not qualify as measurement period adjustments are included in earnings in the period identified. The fair values of the assets acquired and liabilities assumed are based on preliminary estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. While the Company believes these preliminary estimates provide a reasonable basis for estimating the fair value of the assets acquired and liabilities assumed, it will continue to evaluate available information prior to finalization of the amounts. Öhlins Intressenter AB Acquisition The purchase price for the 90.5% ownership interest in Öhlins was $162 million . The remaining 9.5% ownership interest in Öhlins (the “KÖ Interest”) was retained by K Öhlin Holding AB (“Köhlin”). Köhlin has an irrevocable right at any time after the third anniversary of the Öhlins Acquisition to sell the KÖ Interest to the Company. As the redemption of this redeemable noncontrolling interest is not solely within the Company's control, the noncontrolling interest is presented in the temporary equity section of the Company's condensed consolidated balance sheets. The fair value of the KÖ Interest was $17 million and represents its current redemption value at September 30, 2019 . The following table summarizes the preliminary fair values of assets acquired and liabilities assumed as of the acquisition date and the measurement period adjustments made during the nine months ended September 30, 2019 : Initial Allocation Adjustments Revised Allocation Cash, cash equivalents and restricted cash $ 4 $ — $ 4 Customer notes and accounts receivable 19 — 19 Inventories 31 — 31 Prepayments and other current assets 2 — 2 Property, plant, and equipment 8 — 8 Goodwill 28 2 30 Intangibles 135 (2 ) 133 Other assets 9 — 9 Total assets acquired 236 — 236 Short-term debt, including current maturities of long-term debt 10 — 10 Accounts payable 11 — 11 Accrued compensation and employee benefits 12 — 12 Deferred income taxes 18 — 18 Deferred credits and other liabilities 6 — 6 Total liabilities assumed 57 — 57 Redeemable noncontrolling interest 17 — 17 Net assets acquired $ 162 $ — $ 162 The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the intangible assets, deferred income tax assets and liabilities, and redeemable noncontrolling interest. Goodwill of $30 million was recognized as part of the acquisition and is reflected in the Ride Performance segment. During the nine months ended September 30, 2019 , the Company adjusted the initial allocation of the total purchase consideration, which resulted in a $2 million increase to goodwill. The goodwill consists of the Company’s expected future economic benefits that will result from the acquisition of Öhlins’ technology, which will allow the Company to more rapidly grow its product offerings for current and future customers, as well as assist the Company in obtaining a larger share of business in developing mobility markets. None of the goodwill is deductible for tax purposes. Other intangible assets acquired include the following: Estimated Fair Value Weighted-Average Useful Lives Definite-lived intangible assets: Customer platforms and relationships $ 37 10 years Technology rights 41 10 years Total definite-lived intangible assets 78 Indefinite-lived intangible assets: Trade names and trademarks 55 Total $ 133 The Company recorded a $5 million step-up of inventory to its fair value as of the acquisition date based on the preliminary valuation and recognized $5 million as a non-cash charge to cost of goods sold during the nine months ended September 30, 2019 related to the amortization of this step-up, as the acquired inventory was sold. Pro Forma Results Pro forma results of operations have not been presented because the effects of the Öhlins Acquisition were not material to the Company’s condensed consolidated results of operations. Acquisition of Federal-Mogul The Company finalized the valuation of the assets and liabilities of the Federal-Mogul Acquisition during the third quarter of 2019. During the nine months ended September 30, 2019 , the Company made measurement period adjustments based on further evaluation of available information to facts and circumstances that existed as of the acquisition date. The following table summarizes the final fair values of assets acquired and liabilities assumed as of the acquisition date and the measurement period adjustments made during the nine months ended September 30, 2019 : Initial Allocation Adjustments Final Allocation Cash, cash equivalents and restricted cash $ 277 $ — $ 277 Customer notes and accounts receivable 1,258 (4 ) 1,254 Other receivables 62 — 62 Inventories 1,551 (8 ) 1,543 Prepayments and other current assets 198 — 198 Property, plant and equipment 1,711 (28 ) 1,683 Long-term receivables 48 — 48 Goodwill 825 (22 ) 803 Intangibles 1,530 47 1,577 Investments in nonconsolidated affiliates 528 (4 ) 524 Deferred income taxes 166 30 196 Other assets 55 (5 ) 50 Total assets acquired 8,209 6 8,215 Short-term debt, including current maturities of long-term debt 130 — 130 Accounts payable 957 4 961 Accrued compensation and employee benefits 231 — 231 Accrued income taxes 49 — 49 Accrued expenses and other current liabilities 522 (7 ) 515 Long-term debt 1,315 — 1,315 Deferred income taxes 56 24 80 Pension and postretirement benefits 879 — 879 Deferred credits and other liabilities 124 (5 ) 119 Total liabilities assumed 4,263 16 4,279 Redeemable noncontrolling interests 96 (8 ) 88 Noncontrolling interests 143 (2 ) 141 Net assets and noncontrolling interests acquired $ 3,707 $ — $ 3,707 Goodwill of $343 million was allocated to the Powertrain segment, $395 million was allocated to the Motorparts segment, and $65 million was allocated to the Ride Performance segment. The goodwill consists of the Company's expected future economic benefits that will arise from expected future product sales and synergies from combining Federal-Mogul with its existing portfolio of products. None of the goodwill is deductible for tax purposes. Other intangible assets acquired include the following: Estimated Fair Value Weighted-Average Useful Lives Definite-lived intangible assets: Customer platforms and relationships $ 953 10 years Technology rights 66 10 years Packaged kits know-how 54 10 years Catalogs 47 10 years Licensing agreements 64 4.5 years Land use rights 30 42.8 years Total definite-lived intangible assets 1,214 10.5 years Indefinite-lived intangible assets: Trade names and trademarks 363 Total $ 1,577 The Company recorded a $149 million step-up of inventory to its fair value as of the acquisition date. The Company recognized $44 million as a non-cash charge to cost of goods sold during the nine months ended September 30, 2019 related to the amortization of this step-up, as the acquired inventory was sold. The Company recognized $105 million as a non-cash charge to cost of goods sold during the year ended December 31, 2018 . As of September 30, 2019 , there is no remaining inventory step-up to be amortized. In addition, the Company acquired $81 million in redeemable noncontrolling interests related to a subsidiary from the Federal-Mogul Acquisition. The Company initiated the process to make a tender offer for the shares it does not own due to the change in control in accordance with local regulations triggered by the acquisition. It is probable these shares will become redeemable within the next year under the tender offer at a price that is representative of fair value and as a result, the noncontrolling interest is presented in the temporary equity section of the Company’s condensed consolidated balance sheets. The carrying amount for this redeemable noncontrolling interest represents its current redemption value at September 30, 2019 . The Company's condensed consolidated statements of income (loss) for the nine months ended September 30, 2019 included net sales and operating revenues of $5,537 million and net loss of $34 million associated with the operating results of Federal-Mogul. Pro Forma Results The following table summarizes, on a pro forma basis, the combined results of operations of the Company and the Federal-Mogul Acquisition, and the related financing, if the transaction had occurred as of January 1, 2017. The pro forma results are not necessarily indicative of either the actual consolidated results had the Federal-Mogul Acquisition occurred on January 1, 2017 or of future consolidated operating results.

Pro forma adjustments described above have been tax affected using the Company's effective rate during the respective periods. Assets Held for Sale On March 1, 2019, the Company sold its wipers business in the Motorparts segment for a sale price of $29 million , subject to adjustment based on terms of the sale agreement. Proceeds from the sale were $22 million , subject to customary working capital adjustments. Certain assets and liabilities of the business are still classified as held for sale within the condensed consolidated balance sheet as of September 30, 2019 and were transferred to the buyer on October 1, 2019. In August 2019, the Company executed a letter of intent to sell a non-core business in the Motorparts segment for a sale price of $24 million , subject to adjustment, as the Company continues to rationalize its product portfolio and focus on core product lines. As of September 30, 2019 , proceeds from the sale would have been $24 million . The related assets and liabilities were classified as held for sale as of September 30, 2019 . The transaction is expected to close within the next year. The related assets and liabilities were classified as held for sale as of September 30, 2019 and December 31, 2018 : September 30, 2019 December 31, 2018 Assets Receivables $ 8 $ — Inventories 7 33 Other current assets 3 5 Long-lived assets 16 23 Goodwill 4 — Impairment on carrying value (8 ) — Total assets held for sale $ 30 $ 61 Liabilities Accounts payable $ 4 $ 21 Accrued liabilities — 7 Other liabilities 1 11 Total liabilities held for sale $ 5 $ 39 The assets and liabilities held for sale are recorded in “ Prepayments and other current assets ” and “ Accrued expenses and other current liabilities ” in the consolidated balance sheets as of September 30, 2019 and December 31, 2018

Restructuring and Related Activities [Abstract]
Restructuring Charges, Asset Impairments, and Other, Net	4. Restructuring Charges, Asset Impairments, and Other, Net Restructuring and Other Charges The Company's restructuring activities are undertaken as necessary to execute management's strategy and streamline operations, consolidate and take advantage of available capacity and resources, and ultimately achieve net cost reductions. Restructuring activities include efforts to integrate and rationalize the Company's businesses and to relocate operations to best cost locations. The Company's restructuring charges consist primarily of employee costs (principally severance and/or termination benefits), facility closure and exit costs, and other. For the three and nine months ended September 30, 2019 and 2018 , restructuring charges, asset impairments, and other by segment are as follows: Three Months Ended September 30, 2019 Clean Air Powertrain Ride Performance (1) Motorparts Corporate Total Severance and other charges, net $ 6 $ 11 $ 15 $ 2 $ 1 $ 35 Impairment of assets held for sale — — — 8 — 8 Total restructuring charges, asset impairments, and other $ 6 $ 11 $ 15 $ 10 $ 1 $ 43 (1) The Ride Performance segment includes $10 million of other charges for the three months ended September 30, 2019.

Nine Months Ended September 30, 2018 Clean Air Powertrain Ride Performance Motorparts Corporate Total Severance and other charges, net $ 19 $ — $ 27 $ 6 $ 3 $ 55 Other non-restructuring asset impairments — — — — 2 2 Total restructuring charges, asset impairments, and other $ 19 $ — $ 27 $ 6 $ 5 $ 57 During the three and nine months ended September 30, 2019 , the Company incurred $3 million and $12 million in restructuring and related costs and reduced previously recorded estimates by $1 million and $3 million related to a restructuring plan designed to achieve a portion of the synergies the Company anticipates achieving in connection with the Federal-Mogul Acquisition. Pursuant to the plan, the Company will reduce its headcount globally across all segments.

During the nine months ended September 30, 2019 , the Company made the following adjustments to goodwill in the measurement period to the preliminary purchase price allocation for the Acquisitions: • an increase of $2 million for the Öhlins Acquisition; and • a net decrease of $22 million for the Federal-Mogul Acquisition. The purchase price allocation for the Öhlins Acquisition is preliminary and subject to finalization. The Company's current estimates and assumptions may change as a result. See Note 3, Acquisitions and Divestitures for additional information. During the first quarter of 2019, the Company reorganized the reporting structure of its Aftermarket, Ride Performance, and Motorparts segments and the underlying reporting units within those segments. The Company reassigned assets and liabilities (excluding goodwill) to the reporting units affected. Goodwill was then reassigned to the reporting units using a relative fair value approach based on the fair value of the elements transferred and the fair value of the elements remaining within the original reporting units. The Company tested goodwill for impairment on a pre-reorganization basis and determined there was no impairment for the affected reporting units. The Company also performed an impairment analysis on a post-reorganization basis and determined $60 million of goodwill was impaired for two reporting units within its Ride Performance segment, one of which was a full impairment of the goodwill. As a result, this non-cash charge was recorded in the first quarter of 2019. Goodwill allocated to other reporting units was supported by the valuation performed at that time. During the third quarter of 2019, the Company completed purchase accounting for the Federal-Mogul Acquisition. As a result, the final goodwill allocation was reassigned to the reorganized segments and reporting unit structure that occurred in the first quarter of 2019 using a relative fair value approach and the Company determined an incremental $9 million of goodwill was impaired for one reporting unit in its Ride Performance segment. This non-cash charge was recorded in the three months ended September 30, 2019 and the total impairment charge recognized in the nine months ended September 30, 2019 for the reorganization of the reporting units that occurred in the first quarter of 2019 was $69 million . During the three months ended September 30, 2019 , the Company performed a review of potential triggering events, and concluded no events indicated it was more likely than not that the fair values of its reporting units had declined to below their carrying values at September 30, 2019 . The Company considered the results of the post-reorganized reporting unit changes that occurred in the first quarter of 2019, which indicated nine reporting units with goodwill. Management compared its future projected cash flows as of September 30, 2019 to the future projected cash flows utilized in the valuation performed during the first quarter of 2019 and concluded there is no indication the carrying value of its reporting units would be less than their fair values. If the Company’s market capitalization remains at current levels for a sustained period of time or declines further, and if such a decline becomes indicative the fair value of its reporting units have declined to below their carrying values, the Company will need to determine the fair value of its reporting units which may result in a material non-cash goodwill impairment charge in a future period. At September 30, 2019 and December 31, 2018, the Company's intangible assets consist of the following: September 30, 2019 December 31, 2018 Useful Lives Gross Carrying Value Accumulated Amortization Net Carrying Value Gross Carrying Value Accumulated Amortization Net Carrying Value Definite-lived intangible assets: Customer relationships and platforms 10 years $ 985 $ (98 ) $ 887 $ 964 $ (24 ) $ 940 Customer contract 10 years 8 (6 ) 2 8 (5 ) 3 Patents 10 to 17 years 1 (1 ) — 1 (1 ) — Technology rights 10 to 30 years 131 (34 ) 97 98 (27 ) 71 Packaged kits know-how 10 years 54 (5 ) 49 36 (1 ) 35 Catalogs 10 years 47 (5 ) 42 — — — Licensing agreements 3 to 5 years 62 (14 ) 48 66 (3 ) 63 Land use rights 28 to 46 years 45 (3 ) 42 44 (2 ) 42 1,333 (166 ) 1,167 1,217 (63 ) 1,154 Indefinite-lived intangible assets: Trade names and trademarks 411 — 411 365 — 365 Total $ 1,744 $ (166 ) $ 1,578 $ 1,582 $ (63 ) $ 1,519 The Company recorded definite-lived and indefinite-lived intangible assets of $133 million as a result of the Öhlins Acquisition.

Derivatives and Hedging Activities	Sep. 30, 2019
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	8. Derivatives and Hedging Activities The Company is exposed to market risk, such as fluctuations in foreign currency exchange rates, commodity prices, equity compensation liabilities, and changes in interest rates, which may result in cash flow risks. For exposures not offset within its operations, the Company may enter into various derivative transactions pursuant to its risk management policies, which prohibit holding or issuing derivative financial instruments for speculative purposes. Designation of derivative instruments is performed on a transaction basis to support hedge accounting. The changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the fair value or cash flows of the underlying exposures being hedged. The Company assesses the initial and ongoing effectiveness of its hedging relationships in accordance with its documented policy. Market Risks Foreign Currency Risk — The Company manufactures and sells its products in North America, South America, Asia, Europe, Australia, and Africa. As a result, the Company's financial results could be significantly affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets in which the Company manufactures and sells its products. The Company generally tries to use natural hedges within its foreign currency activities, including the matching of revenues and costs, to minimize foreign currency risk. Where natural hedges are not in place, the Company considers managing certain aspects of its foreign currency activities and larger transactions through the use of foreign currency options or forward contracts. Principal currencies hedged have historically included the U.S. dollar, euro, British pound, Polish zloty, Mexican peso, and Canadian dollar. Concentrations of Credit Risk — Financial instruments including cash equivalents and derivative contracts expose the Company to counterparty credit risk for non-performance. The Company's counterparties for cash equivalents and derivative contracts are banks and financial institutions that meet the Company's requirement of high credit standing. The Company's counterparties for derivative contracts are substantial investment and commercial banks with significant experience using such derivatives. The Company manages its credit risk through policies requiring minimum credit standing and limiting credit exposure to any one counterparty and through monitoring counterparty credit risks. The Company's concentration of credit risk related to derivative contracts at September 30, 2019 and 2018 is not material. Other — The Company presents its derivative positions and any related material collateral under master netting agreements on a net basis. For derivatives designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness. Unrealized gains and losses associated with ineffective hedges, determined using the hypothetical derivative method, are recognized in "Cost of sales" in the condensed consolidated statements of income (loss). Derivative gains and losses included in accumulated other comprehensive income (loss) for effective hedges are reclassified into operations upon recognition of the hedged transaction. Derivative gains and losses associated with undesignated hedges are recognized in "Cost of sales" in the condensed consolidated statements of income (loss). Derivative Instruments Foreign Currency Forward Contracts — The Company enters into foreign currency forward purchase and sale contracts to mitigate its exposure to changes in exchange rates on certain intercompany and third-party trade receivables and payables. In managing its foreign currency exposures, the Company identifies and aggregates existing offsetting positions and then hedges residual exposures through third-party derivative contracts. The gains or losses on these contracts is recognized in "Cost of sales" in the condensed consolidated statements of income (loss). The fair value of foreign currency forward contracts are recorded in "Prepayments and other current assets" or "Accrued expenses and other current liabilities" in the condensed consolidated balance sheets. The fair value of the Company's foreign currency forward contracts was a net asset position of less than $1 million at September 30, 2019 and December 31, 2018 . The following table summarizes by position the notional amounts for foreign currency forward contracts as of September 30, 2019 (all of which mature in 2019): Notional Amount Long positions $ (47 ) Short positions $ 47 Cash-Settled Share Swap Transactions — During 2019, the Company entered into an amended and restated equity swap agreement. The Company selectively uses cash-settled share swaps to reduce market risk associated with its deferred compensation liabilities. These equity deferred compensation liabilities increase as the Company's stock price increases and decrease as the Company's stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing the Company to fix a portion of the liabilities at a stated amount. As of September 30, 2019 , the Company hedged its deferred compensation liability related to approximately 600,000 common share equivalents, an increase from 250,000 common share equivalents as of December 31, 2018 . The fair value of the equity swap agreement is recorded in "Prepayments and other current assets" or "Accrued expenses and other current liabilities" in the condensed consolidated balance sheets. The fair value of the Company's equity swap agreement was a net liability position of $1 million at September 30, 2019 and net asset position of $4 million at December 31, 2018 . Hedging Instruments Cash Flow Hedges — Commodity Price Risk — The Company’s production processes are dependent upon the supply of certain raw materials that are exposed to price fluctuations on the open market. The primary purpose of the Company’s commodity price forward contract activity is to manage the volatility associated with forecasted purchases for up to eighteen months in the future. The Company monitors its commodity price risk exposures regularly to maximize the overall effectiveness of its commodity forward contracts. Principal raw materials hedged include copper and tin. In certain instances within this program, foreign currency forwards may be used in order to match critical terms for commodity exposure. The Company has designated these contracts as cash flow hedging instruments. The Company records unrecognized gains and losses in other comprehensive income (loss) (“OCI or OCL”) and makes regular reclassifying adjustments into “Cost of sales” within the condensed consolidated statements of income (loss) when the underlying hedged transaction is recognized in earnings. The Company had commodity derivatives outstanding with an equivalent notional amount of $26 million as of September 30, 2019 and $27 million as of December 31, 2018 . Substantially all of the commodity price hedge contracts mature within one year . Net Investment Hedge — Foreign Currency Borrowings — The Company has foreign currency denominated debt, €770 million of which was designated as a net investment hedge in certain foreign subsidiaries and affiliates of the Company. Changes to its carrying value are included in shareholders' equity in the foreign currency translation component of OCL and offset against the translation adjustment on the underlying net assets of those foreign subsidiaries and affiliates, which are also recorded in OCL. The Company’s debt instruments are discussed further in Note 10, Debt and Other Financing Arrangements . The following table is a summary of the carrying value of derivative and non-derivative instruments designated as hedges as of September 30, 2019 : Carrying Value Balance sheet classification September 30, 2019 December 31, 2018 Commodity price hedge contracts designated as cash flow hedges Accrued expenses and other current liabilities $ 1 $ 2 Foreign currency borrowings designated as net investment hedges Long-term debt $ 839 $ 863 The following table represents the effects before reclassification into net income of derivative and non-derivative instruments designated as hedges in accumulated other comprehensive income (loss) three and nine month periods ended September 30, 2019 : Amount of gain (loss) recognized in accumulated OCI or OCL (effective portion): Three Months Ended September 30, Nine Months Ended September 30, 2019 2019 Commodity price hedge contracts designated as cash flow hedges $ (1 ) $ — Foreign currency borrowings designated as net investment hedges $ 38 $ 45 The Company estimates less than $1 million included in accumulated OCI or OCL as of September 30, 2019 will be reclassified into earnings within the following 12 months.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	Sep. 30, 2019
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	9. Fair Value of Financial Instruments A three-level valuation hierarchy, based upon observable and unobservable inputs, is used for fair value measurements. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions based on the best evidence available. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fair value hierarchy definition prioritizes the inputs used in measuring fair value into the following levels: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3 — Unobservable inputs based on our own assumptions. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents assets and liabilities included in the Company's condensed consolidated balance sheets as of September 30, 2019 and December 31, 2018 that are recognized at fair value on a recurring basis and indicate the fair value hierarchy utilized to determine such fair value: September 30, 2019 December 31, 2018 Fair value Carrying Fair Carrying Fair Derivative instruments: Equity swap agreement Level 2 $ (1 ) $ (1 ) $ 4 $ 4 Commodity contracts Level 2 $ (1 ) $ (1 ) $ (2 ) $ (2 ) Cash-Settled Share Swap Transactions — The Company's stock price is used as an observable input in determining the fair value of the equity swap. Commodity and Foreign Currency Contracts — The Company calculates the fair value of its commodity contracts and foreign currency contracts using commodity forward rates and currency forward rates, to calculate forward values, and then discounts the forward values. The discount rates for all derivative contracts are based on bank deposit rates. The fair value of the Company's foreign currency forward contracts was a net asset position of less than $1 million at September 30, 2019 and December 31, 2018 . Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis In addition to items measured at fair value on a recurring basis, assets may be measured at fair value on a nonrecurring basis. These assets include long-lived assets and intangible assets which may be written down to fair value as a result of impairment. The Company has determined the fair value measurements related to each of these rely primarily on Company-specific inputs and the Company's assumptions about the use of the assets, as observable inputs are not available (level 3). To determine the fair value of long-lived asset groups, the Company utilizes discounted cash flows expected to be generated by the long-lived asset group. The Company evaluates the carrying value of its goodwill and indefinite-lived intangible assets for impairment annually in the fourth quarter of each year. These fair value measurements require the Company to make significant assumptions and estimates about the extent and timing of future cash flows, discount rates, and growth rates, which are subject to a high degree of uncertainty. The Company believes the assumptions and estimates used to determine the estimated fair value are reasonable, but different assumptions could materially affect the estimated fair value. During the first quarter, the Company reorganized the reporting structure of its Aftermarket, Ride Performance, and Motorparts segments and the underlying reporting units within those segments. See Note 6, Goodwill and Other Intangible Assets , for additional information on the goodwill impairment recognized in the three and nine months ended September 30, 2019 . Financial Instruments Not Carried at Fair Value Estimated fair values of the Company's outstanding debt were: September 30, 2019 December 31, 2018 Fair value Carrying Fair Carrying Fair Long-term debt (including current maturities): Term loans and senior notes Level 2 $ 5,169 $ 4,963 $ 5,307 $ 5,218 The fair value of the Company's public senior notes and private borrowings under its senior credit facility is based on observable inputs, and its borrowings on the revolving credit facility approximate fair value. The Company also had $78 million and $106 million at September 30, 2019 and December 31, 2018 in other debt whose carrying value approximates fair value, which consists primarily of foreign debt with maturities of one year or less. Assets and Liabilities Not Carried at Fair Value The carrying value of cash and cash equivalents, restricted cash, short and long-term receivables, accounts payable, and short-term debt approximates fair value.

(b) Letters of credit reduce the available borrowings under the revolving credit facility, as of September 30, 2019 the revolving credit facility had $20 million in letters of credit outstanding. Interest expense associated with the amortization of the debt issuance costs and original issue discounts recognized in the Company's condensed consolidated statements of income (loss) consist of the following: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Amortization of debt issuance fees $ 5 $ 1 $ 14 $ 3 Included in the table above, is the amortization of debt issuance costs on the revolver, which are $19 million at September 30, 2019 and are recorded in "Other assets" in the condensed consolidated balance sheets. In addition, there was a $3 million and $9 million reduction to interest expense during the three and nine months ended September 30, 2019 related to the accretion of the debt premium on the Senior Secured Notes. New Credit Facility — Other Terms and Conditions — The New Credit Facility also contains two financial maintenance covenants for the revolving credit facility and the Term Loan A facility including a requirement to have a consolidated net leverage ratio (as defined in the New Credit Facility) as of the end of each fiscal quarter of not greater than 4.0 to 1 through September 30, 2019, 3.75 to 1 through September 30, 2020 and 3.5 to 1 thereafter; and a requirement to maintain a consolidated interest coverage ratio (as defined in the New Credit Facility) for any period of four consecutive fiscal quarters of not less than 2.75 to 1. Senior Unsecured Notes and Senior Secured Notes — Other Terms and Conditions — The Senior Unsecured Notes and Senior Secured Notes contain covenants that will, among other things, limit the Company's ability to create liens and enter into sale and leaseback transactions. In addition, the Senior Secured Notes and 2024 Senior Unsecured Notes also require that, as a condition precedent to incurring certain types of indebtedness not otherwise permitted, the Company's consolidated fixed charge coverage ratio, as calculated on a pro forma basis, be greater than 2.00 , as well as containing restrictions on its operations, including limitations on: (i) incurring additional indebtedness; (ii) paying dividends; (iii) distributions and stock repurchases; (iv) investments; (v) asset sales and (vi) mergers and consolidations. Subject to limited exceptions, all of the Company's existing and future material domestic wholly owned subsidiaries fully and unconditionally guarantee its Senior Unsecured Notes and Senior Secured Notes on a joint and several basis. There are no significant restrictions on the ability of the subsidiaries that have guaranteed the Company's Senior Notes to make distributions to the Company. As of September 30, 2019 , the Company was in compliance with all of its financial covenants. Accounts Receivable Securitization and Factoring On-Balance Sheet Arrangements — The Company has securitization programs for some of its accounts receivables, with limited recourse provisions. Borrowings on these securitization programs, which are recorded in short-term debt, at September 30, 2019 and December 31, 2018 are as follows: September 30, 2019 December 31, 2018 Borrowings on securitization programs $ 3 $ 6 Off-Balance Sheet Arrangements — In the Company's European and U.S. accounts receivable factoring programs, accounts receivables are transferred in their entirety to the acquiring entities and are accounted for as a sale. The fair value of assets received as proceeds in exchange for the transfer of accounts receivable under these factoring programs approximates the fair value of such receivables. Certain programs in Europe have deferred purchase price arrangements with the banks. The Company is the servicer of the receivables under some of these arrangements and is responsible for performing all accounts receivable administration functions. Where the Company receives a fee to service and monitor these transferred accounts receivables, such fees are sufficient to offset the costs and as such, a servicing asset or liability is not recorded as a result of such activities. In the U.S and Canada, the Company participates in supply chain financing programs with certain of the Company's aftermarket customers through a drafting program. The amounts outstanding for these factoring and drafting arrangements as of September 30, 2019 and December 31, 2018 are as follows: September 30, 2019 December 31, 2018 (in billions) Accounts receivable outstanding and derecognized $ 1.1 $ 1.0 The deferred purchase price receivable as of September 30, 2019 and December 31, 2018 is as follows: September 30, 2019 December 31, 2018 Deferred purchase price receivable $ 47 $ 154 Proceeds from the factoring of accounts receivable qualifying as sales are as follows: Three months ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 (in billions) Proceeds from factoring qualifying as sales $ 1.1 $ 0.6 $ 3.6 $ 2.1 Financing charges associated with the factoring of receivables are as follows: Three months ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Financing charges on sale of receivables (a) $ 9 $ 3 $ 23 $ 8 (a) Amount is included in "Interest expense" in the condensed consolidated statements of income (loss).

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes For interim tax reporting, the Company estimates its annual effective tax rate and applies it to year-to-date ordinary income. Jurisdictions where no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The effect of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a quarter due to the mix and timing of actual earnings versus annual projections. The tax effects of certain items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur. For the three months ended September 30, 2019 , the Company recorded income tax benefit of $9 million on income from continuing operations before income taxes of $ 69 million . This compares to income tax expense of $ 22 million on income from continuing operations before income taxes of $ 88 million in the three months ended September 30, 2018 . For the nine months ended September 30, 2019 , the Company recorded income tax expense of $ 5 million on income from continuing operations before income taxes of $ 23 million . This compares to income tax expense of $ 73 million on income from continuing operations before income taxes of $ 276 million in the nine months ended September 30, 2018 . Income tax expense for the three and nine months ended September 30, 2019 differs from the U.S. statutory rate due primarily to $33 million of net tax benefit recognized relating to a valuation allowance release for an entity in Spain, pre-tax income taxed at rates higher than the U.S. statutory rate, and pre-tax losses with no tax benefit. Income tax expense for the three and nine months ended September 30, 2018 differs from the U.S. statutory rate due primarily to $5 million and $12 million of tax benefit recognized relating to acquisition and restructuring charges, $10 million of tax benefit recognized for valuation allowance release at our Australia entities, pre-tax income taxed at rates lower than the U.S. statutory rate, and pre-tax losses with no tax benefit. In addition, during the three and nine months ended September 30, 2018, $9 million and $11 million of tax expense was recognized for changes in the toll tax discussed below. On December 22, 2017, the Tax Cuts and Jobs Act ("TCJA") was enacted into U.S. law, which, among other provisions, lowered the corporate income tax rate effective January 1, 2018 from 35% to 21%, and implemented significant changes with respect to U.S. tax treatment of earnings originating from outside the U.S. Many of the provisions of TCJA are subject to regulatory interpretation and U.S. state conforming enactments. The Internal Revenue Service (IRS) issued final regulations, effective on February 5, 2019, which provided additional guidance to assist taxpayers in computing the toll tax. Based on the final regulations a $2 million tax benefit was recognized for the nine months ended September 30, 2019 . The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required or should be adjusted. This assessment considers, among other matters, the nature, frequency and amount of recent losses, the duration of statutory carryforward periods, and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified. If recent operational improvements continue in our foreign subsidiaries, the Company believes it is reasonably possible sufficient positive evidence may be available to release all, or a portion, of its valuation allowance in the next twelve months in certain jurisdictions. This may result in a one-time tax benefit of up to $4 million , primarily related to China and France. The Company believes it is reasonably possible up to $9 million in unrecognized tax benefits related to the expiration of foreign statute of limitations and the conclusion of income tax examinations may be recognized within the next twelve months .

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. Commitments and Contingencies Environmental Matters The Company is subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which it operates. The Company has been notified by the U.S. Environmental Protection Agency, other national environmental agencies, and various provincial and state agencies it may be a potentially responsible party (“PRP”) under such laws for the cost of remediating hazardous substances pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and other national and state or provincial environmental laws. PRP designation typically requires the funding of site investigations and subsequent remedial activities. Many of the sites that are likely to be the costliest to remediate are often current or former commercial waste disposal facilities to which numerous companies sent wastes. Despite the potential joint and several liability which might be imposed on the Company under CERCLA and some of the other laws pertaining to these sites, its share of the total waste sent to these sites generally has been small. The Company believes its exposure for liability at these sites is not material. On a global basis, the Company has also identified certain other present and former properties at which it may be responsible for cleaning up or addressing environmental contamination, in some cases as a result of contractual commitments and/or federal or state environmental laws. The Company is seeking to resolve its responsibilities for those sites for which a claim has been received. The Company expenses or capitalizes, as appropriate, expenditures for ongoing compliance with environmental regulations. As of September 30, 2019 , the Company has an obligation to remediate or contribute towards the remediation of certain sites, including the sites discussed above at which it may be a PRP. The Company maintains the aggregated estimated share of environmental remediation costs for all these sites on a discounted basis in the condensed consolidated balance sheets as follows: September 30, 2019 December 31, 2018 Accrued expenses and other current liabilities $ 8 $ 12 Deferred credits and other liabilities 29 28 $ 37 $ 40 For those locations where the liability was discounted, the weighted average discount rate used was 1.3% and 2.9% at September 30, 2019 and December 31, 2018. The Company's expected payments of environmental remediation costs for non-indemnified locations are estimated to be approximately: 2019 2020 2021 2022 2023 2024 and thereafter Expected payments $ 5 $ 5 $ 3 $ 3 $ 2 $ 17 Based on information known to the Company from site investigations and the professional judgment of consultants, the Company has established reserves it believes are adequate for these costs. Although the Company believes these estimates of remediation costs are reasonable and are based on the latest available information, the costs are estimates, difficult to quantify based on the complexity of the issues, and are subject to revision as more information becomes available about the extent of remediation required. At some sites, the Company expects other parties will contribute to the remediation costs. In addition, certain environmental statutes provide the Company's liability could be joint and several, meaning the Company could be required to pay amounts in excess of its share of remediation costs. The financial strength of the other PRPs at these sites has been considered, where appropriate, in the determination of the estimated liability. The Company does not believe any potential costs associated with its current status as a PRP, or as a liable party at the other locations referenced herein, will be material to its annual consolidated financial position, results of operations, or liquidity. Asset Retirement Obligations The Company’s primary asset retirement obligations ("ARO") activities relate to the removal of hazardous building materials at its facilities. The Company records an ARO at fair value upon initial recognition when the amount is probable and can be reasonably estimated. ARO fair values are determined based on the Company’s determination of what a third party would charge to perform the remediation activities, generally using a present value technique. The Company maintains ARO liabilities in the condensed consolidated balance sheets as follows: September 30, 2019 December 31, 2018 Accrued expenses and other current liabilities $ 3 $ 3 Deferred credits and other liabilities 12 12 $ 15 $ 15 Antitrust Investigations and Litigation On March 25, 2014, representatives of the European Commission (EC) were at Tenneco GmbH's Edenkoben, Germany administrative facility to gather information in connection with an ongoing global antitrust investigation concerning multiple automotive suppliers. On the same date, the Company also received a related subpoena from the U.S. Department of Justice (“DOJ”). On November 5, 2014, the DOJ granted conditional leniency to the Company, its subsidiaries, and its 50% affiliates as of such date ("2014 Tenneco Entities") pursuant to an agreement the Company entered into under the Antitrust Division's Corporate Leniency Policy. This agreement provides important benefits to the 2014 Tenneco Entities in exchange for the Company's self-reporting of matters to the DOJ and its continuing full cooperation with the DOJ's resulting investigation. For example, the DOJ will not bring any criminal antitrust prosecution against the 2014 Tenneco Entities, nor seek any criminal fines or penalties, in connection with the matters the Company reported to the DOJ. Additionally, there are limits on the liability of the 2014 Tenneco Entities related to any follow-on civil antitrust litigation in the United States. The limits include single rather than treble damages, as well as relief from joint and several antitrust liability with other relevant civil antitrust action defendants. These limits are subject to the Company satisfying the DOJ and any court presiding over such follow-on civil litigation. On April 27, 2017, the Company received notification from the EC that it has administratively closed its global antitrust inquiry regarding the production, assembly, and supply of complete exhaust systems. No charges against the Company or any other competitor were initiated at any time and the EC inquiry is now closed. Certain other competition agencies are also investigating possible violations of antitrust laws relating to products supplied by the Company and its subsidiaries, including Federal-Mogul. The Company has cooperated and continues to cooperate fully with all of these antitrust investigations and take other actions to minimize its potential exposure. The Company and certain of its competitors are also currently defendants in civil putative class action litigation and are subject to similar claims filed by other plaintiffs, in the United States and Canada. More related lawsuits may be filed, including in other jurisdictions. Plaintiffs in these cases generally allege that defendants have engaged in anticompetitive conduct, in violation of federal and state laws, relating to the sale of automotive exhaust systems or components thereof. Plaintiffs seek to recover, on behalf of themselves and various purported classes of purchasers, injunctive relief, damages and attorneys’ fees. However, as explained above, because the DOJ granted conditional leniency to the 2014 Tenneco Entities, the Company's civil liability in U.S. follow-on actions with respect to these entities is limited to single damages and the Company will not be jointly and severally liable with the other defendants, provided that the Company has satisfied its obligations under the DOJ leniency agreement and approval is granted by the presiding court. Typically, exposure for follow-on actions in Canada is less than the exposure for U.S. follow-on actions. Following the EC's decision to administratively close its antitrust inquiry into exhaust systems in 2017, receipt by the 2014 Tenneco Entities of conditional leniency from the DOJ and discussions during the third quarter of 2017 following the appointment of a special settlement master in the civil putative class action cases pending against the Company and/or certain of its competitors in the United States, the Company continues to vigorously defend itself and/or take actions to minimize its potential exposure to matters pertaining to the global antitrust investigation, including engaging in settlement discussions when it is in the best interests of the Company and its stockholders. For example, in October 2017, the Company settled an administrative action brought by Brazil's competition authority for an amount that was not material. In December 2018, the Company settled a separate administrative action brought by Brazil’s competition authority against a Federal-Mogul subsidiary, also for an amount that was not material. Additionally, in February 2018, the Company settled civil putative class action litigation in the United States brought by classes of direct purchasers, end-payors and auto dealers. No other classes of plaintiffs have brought claims against the Company in the United States. Based upon those earlier developments, including settlement discussions, the Company established a reserve of $132 million in its second quarter 2017 financial results for settlement costs that were probable, reasonably estimable, and expected to be necessary to resolve its antitrust matters globally, which primarily involves the resolution of civil suits and related claims. Of the $132 million reserve that was established, $79 million was paid through September 30, 2019 . In connection with the resolution of certain claims, $9 million was released from the reserve in the third quarter of 2019 and the Company expects to pay $30 million in the first quarter of 2020 from amounts that were included in the reserve. The reserve of $44 million as of September 30, 2019 is recorded in accrued expenses and other current liabilities in the Company's condensed consolidated balance sheets. While the Company, including its Federal-Mogul subsidiaries, continues to cooperate with certain competition agencies investigating possible violations of antitrust laws relating to products supplied by the Company, and the Company may be subject to other civil lawsuits and/or related claims, no amount of this reserve is attributable to matters with the DOJ or the EC, and no such amount is expected based on current information. The Company's reserve for its antitrust matters is based upon all currently available information and an assessment of the probability of events for those matters where the Company can make a reasonable estimate of the costs to resolve such outstanding matters. The Company's estimate involves significant judgment, given the number, variety and potential outcomes of actual and potential claims, the uncertainty of future rulings and approvals by a court or other authority, the behavior or incentives of adverse parties or regulatory authorities, and other factors outside of its control. As a result, the Company's reserve may change from time to time, and actual costs may vary. Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on current information, the Company does not expect any such change in the reserve will have a material adverse effect on the Company's annual consolidated financial position, results of operations or liquidity. Other Legal Proceedings, Claims and Investigations For many years the Company has been and continues to be subject to lawsuits initiated by claimants alleging health problems as a result of exposure to asbestos. The Company's current docket of active and inactive cases is less than 500 cases in the United States and less than 50 in Europe. With respect to the claims filed in the United States, the substantial majority of the claims are related to alleged exposure to asbestos in the Company's line of Walker® exhaust automotive products although a significant number of those claims appear also to involve occupational exposures sustained in industries other than automotive. A small number of claims have been asserted against one of the Company's subsidiaries by railroad workers alleging exposure to asbestos products in railroad cars. The Company believes, based on scientific and other evidence, it is unlikely that U.S. claimants were exposed to asbestos by the Company's former products and that, in any event, they would not be at increased risk of asbestos-related disease based on their work with these products. Further, many of these cases involve numerous defendants. Additionally, in many cases the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. With respect to the claims filed in Europe, the substantial majority relate to occupational exposure claims brought by current and former employees of Federal-Mogul facilities in France and amounts paid out were not material. A small number of occupational exposure claims have also been asserted against Federal-Mogul entities in Italy and Spain. As major asbestos manufacturers and/or users continue to go out of business or file for bankruptcy, the Company may experience an increased number of these claims. The Company vigorously defends itself against these claims as part of its ordinary course of business. In future periods, the Company could be subject to cash costs or charges to earnings if any of these matters are resolved unfavorably to the Company. To date, with respect to claims that have proceeded sufficiently through the judicial process, the Company has regularly achieved favorable resolutions. Accordingly, the Company presently believes that these asbestos-related claims will not have a material adverse effect on the Company's annual consolidated financial position, results of operations or liquidity. The Company is also from time to time involved in other legal proceedings, claims or investigations. Some of these matters involve allegations of damages against the Company relating to environmental liabilities (including toxic tort, property damage and remediation), intellectual property matters (including patent, trademark and copyright infringement, and licensing disputes), personal injury claims (including injuries due to product failure, design or warning issues, and other product liability related matters), taxes, unclaimed property, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. Additionally, some of these matters involve allegations relating to legal compliance. While the Company vigorously defends itself against all of these legal proceedings, claims and investigations and take other actions to minimize its potential exposure, in future periods, the Company could be subject to cash costs or charges to earnings if any of these matters are resolved on unfavorable terms. Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on current information, including the Company's assessment of the merits of the particular claim, except as described above under "Antitrust Investigations and Litigation", the Company does expect the legal proceedings, claims or investigations currently pending against it will have any material adverse effect on its annual consolidated financial position, results of operations or liquidity. Warranty Matters The Company provides warranties on some of its products. The warranty terms vary but range from one year up to limited lifetime warranties on some of its premium aftermarket products. Provisions for estimated expenses related to product warranty are made at the time products are sold or when specific warranty issues are identified with the Company's products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims. The Company believes the warranty reserve is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. The reserve is included in both current and long-term liabilities on the condensed consolidated balance sheets. Below is a table that shows the activity in the warranty accrual accounts: 2019 2018 Balance as of December 31 of the prior year $ 45 $ 26 Accruals related to product warranties 5 6 Reductions for payments made (2 ) (3 ) Foreign currency — — Balance as of March 31 48 29 Accruals related to product warranties 16 2 Reductions for payments made (11 ) (2 ) Foreign currency — — Balance as of June 30 53 29 Accruals related to product warranties 2 5 Reductions for payments made (2 ) (6 ) Foreign currency (1 ) — Balance as of September 30 $ 52 $ 28

Leases

Leases [Abstract]
Leases	14. Leases The Company has operating and finance leases for real estate and equipment. Generally, the leases have remaining terms of one month to ten years . Leases with an initial term of 12 months or less which do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. In addition, some leases include options to terminate the lease. The Company generally negotiates these termination clauses in anticipation of any changes in market conditions; however, because a termination option requires approval from management, the Company assumes the majority of its termination options will not be exercised when determining the lease term. The Company has elected the practical expedient to not separate non-lease components from the lease components to which they relate, and instead account for each separate lease and non-lease component associated with that lease component as a single lease component for all underlying asset classes. Accordingly, all costs associated with a lease contract are accounted for as lease cost. Lease expense is recorded in operating expenses in the results of operations. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable portion of lease payments is not included in the computation of the right of use assets or lease liabilities. Rather, variable payments, other than those dependent upon a market index or rate, are expensed when the obligation for those payments is incurred and are included in "Cost of sales" and "Selling, general, and administrative" within the condensed consolidated statements of income (loss). The Company does not include significant restrictions or covenants in its lease agreements, and residual value guarantees are generally not included within its operating leases. The components of lease expense were as follows: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Operating lease expense $ 33 $ 97 Finance lease expense Amortization of right-of-use assets 1 1 Short-term lease expense 3 7 Variable lease expense 5 25 Sublease income (1 ) (1 ) Total lease expense $ 41 $ 129 Other information related to leases was as follows: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 43 $ 125 Supplemental balance sheet information related to leases was as follows: September 30, 2019 Operating leases Operating lease right-of-use assets (a) $ 342 Other current liabilities (b) $ 101 Other long-term liabilities (c) 237 Total operating lease liabilities $ 338 Finance leases Property, plant and equipment, gross $ 2 Accumulated depreciation 1 Total finance lease right-of-use assets $ 1 Other current liabilities (b) $ 1 Other long-term liabilities (c) 1 Total finance lease liabilities $ 2 (a) Included in "Other assets" in the condensed consolidated balance sheets.

Leases	14. Leases The Company has operating and finance leases for real estate and equipment. Generally, the leases have remaining terms of one month to ten years . Leases with an initial term of 12 months or less which do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. In addition, some leases include options to terminate the lease. The Company generally negotiates these termination clauses in anticipation of any changes in market conditions; however, because a termination option requires approval from management, the Company assumes the majority of its termination options will not be exercised when determining the lease term. The Company has elected the practical expedient to not separate non-lease components from the lease components to which they relate, and instead account for each separate lease and non-lease component associated with that lease component as a single lease component for all underlying asset classes. Accordingly, all costs associated with a lease contract are accounted for as lease cost. Lease expense is recorded in operating expenses in the results of operations. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable portion of lease payments is not included in the computation of the right of use assets or lease liabilities. Rather, variable payments, other than those dependent upon a market index or rate, are expensed when the obligation for those payments is incurred and are included in "Cost of sales" and "Selling, general, and administrative" within the condensed consolidated statements of income (loss). The Company does not include significant restrictions or covenants in its lease agreements, and residual value guarantees are generally not included within its operating leases. The components of lease expense were as follows: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Operating lease expense $ 33 $ 97 Finance lease expense Amortization of right-of-use assets 1 1 Short-term lease expense 3 7 Variable lease expense 5 25 Sublease income (1 ) (1 ) Total lease expense $ 41 $ 129 Other information related to leases was as follows: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 43 $ 125 Supplemental balance sheet information related to leases was as follows: September 30, 2019 Operating leases Operating lease right-of-use assets (a) $ 342 Other current liabilities (b) $ 101 Other long-term liabilities (c) 237 Total operating lease liabilities $ 338 Finance leases Property, plant and equipment, gross $ 2 Accumulated depreciation 1 Total finance lease right-of-use assets $ 1 Other current liabilities (b) $ 1 Other long-term liabilities (c) 1 Total finance lease liabilities $ 2 (a) Included in "Other assets" in the condensed consolidated balance sheets.

Segment Information	Sep. 30, 2019
Segment Reporting [Abstract]
Segment Information	17. Segment Information The Company intends to separate its businesses to form two independent companies, DRiV and New Tenneco. As such, the Company began to manage and report its DRiV businesses through two new operating segments, in the first quarter of 2019, as compared to the three operating segments it had previously reported. The DRiV operating segments consist of Motorparts and Ride Performance. The new Motorparts operating segment consists of the previously reported Aftermarket operating segment as well as the aftermarket portion of the previously reported Motorparts operating segment. The Ride Performance operating segment consists of the previously reported Ride Performance operating segment as well as the OE Braking business that was included in the previously reported Motorparts operating segment. As such, prior period operating segment results have been conformed to reflect the Company's current operating segments. The future New Tenneco consists of two existing operating segments, Powertrain and Clean Air. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the four operating segments as "Corporate." Management uses EBITDA including noncontrolling interests as the key performance measure of segment profitability and uses the measure in its financial and operational decision making processes, for internal reporting, and for planning and forecasting purposes to effectively allocate resources. EBITDA including noncontrolling interests is defined as earnings before interest expense, income taxes, noncontrolling interests, and depreciation and amortization. Segment assets are not presented as it is not a measure reviewed by the Chief Operating Decision Maker in allocating resources and assessing performance. EBITDA including noncontrolling interests should not be considered a substitute for results prepared in accordance with US GAAP and should not be considered an alternative to net income, which is the most directly comparable financial measure to EBITDA including noncontrolling interests that is in accordance with US GAAP. EBITDA including noncontrolling interests, as determined and measured by the Company, should not be compared to similarly titled measures reported by other companies.

Summary of Accounting Policies (Policies)	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — Interim Financial Statements Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These statements include all adjustments (consisting of normal recurring adjustments) management believes are necessary to fairly state the results of operations, comprehensive income, financial position, changes in shareholders' equity, and cash flows. The Company's management believes the disclosures are adequate to make the information presented not misleading when read in conjunction with the audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2018 , which was filed with the Securities and Exchange Commission on March 18, 2019. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The Company has previously announced its intentions to separate its businesses through a spinoff transaction in mid-2020 to form two new, independent publicly traded companies, an Aftermarket and Ride Performance company ("DRiV") and a new Powertrain Technology company ("New Tenneco"). Tenneco remains committed to the separation of the businesses and continues to execute its plan for the spinoff. Additionally, the company is evaluating multiple strategic options to deleverage and facilitate the separation. Certain of these options could help mitigate the effect of challenging market conditions, which, if current trends were to continue, would likely affect the company’s ability to complete a separation in the mid-year 2020 time range. In preparation for the separation, the Company began to manage and report its DRiV businesses through two new operating segments, in the first quarter of 2019, as compared to the three operating segments it had previously reported. The DRiV operating segments consist of Motorparts and Ride Performance. The new Motorparts operating segment consists of the previously reported Aftermarket operating segment as well as the aftermarket portion of the previously reported Motorparts operating segment. The Ride Performance operating segment consists of the previously reported Ride Performance operating segment as well as the OE Braking business that was included in the previously reported Motorparts operating segment. As such, prior period operating segment results and related disclosures have been conformed to reflect the Company's current operating segments. The future New Tenneco consists of two existing operating segments, Powertrain and Clean Air. See Note 17, Segment Information .
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests — The Company has noncontrolling interests with redemption features. These redemption features could require the Company to make an offer to purchase the noncontrolling interests at fair value in the event of a change in control of Tenneco Inc. or certain of its subsidiaries. The redemption of these redeemable noncontrolling interests is not solely within the Company's control. Accordingly, these noncontrolling interests are presented in the temporary equity section of the Company's condensed consolidated balance sheets. The Company does not believe it is probable the redemption features related to these noncontrolling interest securities will be triggered, as a change in control event is generally not probable until it occurs, except as discussed in
Earnings (loss) per share	Earnings (loss) per share —
Reclassifications	Reclassifications: Certain amounts in the prior years have been aggregated or disaggregated to conform to current year presentation. These reclassifications have no effect on previously reported earnings before income taxes and noncontrolling interests or net income, other comprehensive income (loss), current or total assets, current or total liabilities, and the cash provided (used) by operating, investing or financing activities within the condensed consolidated financial statements.
New Accounting Pronouncements	New Accounting Pronouncements Adoption of New Accounting Standards Comprehensive income — In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220). The amendments in this update allow a reclassification from accumulated other comprehensive income (loss) to accumulated deficit for stranded tax effects resulting from the Tax Cuts and Jobs Act ("TCJA"). The Company has elected not to adopt the optional reclassification. Leases — In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update supersedes the lease requirements in Topic 840, Leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted this update on January 1, 2019 using the modified retrospective method without the recasting of comparative periods’ financial information, as permitted by the transition guidance. The Company adopted the package of practical expedients that allows companies to not reassess its previous conclusions related to contracts that contain leases, existing lease classification, and initial direct costs, and to carry forward its historical conclusions. It elected the land easements practical expedient allowing the Company not to reassess whether existing or expired land easements not accounted for as leases under previous guidance are or contain leases under the new guidance. It also did not adopt the hindsight practical expedient and has also made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases will be expensed over the lease term. As a part of the implementation effort, the Company reviewed its internal control structure and modified and augmented existing controls, as necessary. The adoption of the new standard resulted in the recording of additional lease assets and lease liabilities of $387 million and $383 million , and a reduction of favorable lease intangibles of $4 million as of January 1, 2019. The standard did not materially affect the Company's condensed consolidated financial position or results of operations and had no effect on cash flows. See Note 14, Leases . Accounting Standards Issued But Not Yet Adopted Intangibles — In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for interim and annual periods for the Company beginning on January 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the potential effect of this new guidance on its financial statements. Retirement benefits — In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). The amendments in this update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The new standard (i) requires the removal of disclosures that are no longer considered cost beneficial; (ii) clarifies specific requirements of certain disclosures; and (iii) adds new disclosure requirements, including reasons for significant gains and losses related to changes in the benefit obligation. The amendments in this update are effective for fiscal years ending after December 15, 2020 with early adoption permitted. The Company is currently evaluating the potential effect of this new guidance on its financial statements and will include the enhanced disclosures in the consolidated financial statements upon adoption. Fair value measurements — In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. The Company is currently evaluating the potential effect of this new guidance on its financial statements but does not expect this guidance to have a material effect on its consolidated financial statements.
