Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Presentation	Consolidation and Presentation As you read the accompanying financial statements you should also read our Annual Report on Form 10-K for the year ended December 31, 2015 . In our opinion, the accompanying unaudited financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly Tenneco Inc.’s results of operations, comprehensive income, financial position, cash flows, and changes in shareholders’ equity for the periods indicated. We have prepared the unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (U.S. GAAP) for annual financial statements. Our condensed consolidated financial statements include all majority-owned subsidiaries. We carry investments in 20 percent to 50 percent owned companies in which the Company does not have a controlling interest, as equity method investments, at cost plus equity in undistributed earnings since the date of acquisition and cumulative translation adjustments. We have eliminated all intercompany transactions. Prepayments and Other Prepayments and other included $134 million and $107 million at September 30, 2016 and December 31, 2015 , respectively, for in-process tools and dies that we are building for our original equipment customers. Accounts Payable Accounts payable included $108 million and $93 million at September 30, 2016 and December 31, 2015 , respectively, for accrued compensation and $20 million and $17 million at September 30, 2016 and December 31, 2015 , respectively, for bank overdrafts at our European subsidiaries.

Fair Value Disclosures [Abstract]
Financial Instruments	Financial Instruments The net carrying and estimated fair values of our financial instruments by class at September 30, 2016 and December 31, 2015 were as follows: September 30, 2016 December 31, 2015 Net Carrying Amount Fair Value Net Carrying Amount Fair Value (Millions) Long-term debt (including current maturities) $ 1,311 $ 1,344 $ 1,125 $ 1,160 Instruments with off-balance sheet risk: Foreign exchange forward contracts: Asset derivative contracts 1 1 1 1 Asset and Liability Instruments — The fair value of cash and cash equivalents, short and long-term receivables, accounts payable, and short-term debt was considered to be the same as or was not determined to be materially different from the carrying amount. Long-term Debt — The fair value of our public fixed rate senior notes is based on quoted market prices (level 1). The fair value of our private borrowings under our senior credit facility and other long-term debt instruments is based on the market value of debt with similar maturities, interest rates and risk characteristics (level 2). The fair value of our level 1 debt, as classified in the fair value hierarchy, was $744 million and $748 million at September 30, 2016 and December 31, 2015 , respectively. We have classified $584 million and $390 million as level 2 in the fair value hierarchy at September 30, 2016 and December 31, 2015 , respectively, since we utilize valuation inputs that are observable both directly and indirectly. We classified the remaining $16 million and $22 million , consisting of foreign subsidiary debt, as level 3 in the fair value hierarchy at September 30, 2016 and December 31, 2015 , respectively. 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. Foreign Exchange Forward Contracts — When foreign currency exchange rate risk cannot be managed by operational strategies, we use derivative financial instruments, principally foreign currency forward purchase and sales contracts with terms of less than one year , to hedge our exposure to changes in foreign currency exchange rates. Our primary exposure to changes in foreign currency rates results from intercompany loans and accounts receivable and payable in nonfunctional currencies made between affiliates to minimize the need for borrowings from third parties. Additionally, we enter into foreign currency forward purchase and sale contracts to mitigate our exposure to changes in exchange rates on certain intercompany and third-party trade receivables and payables. We manage counter-party credit risk by entering into derivative financial instruments with major financial institutions that can be expected to fully perform under the terms of such agreements. We do not enter into derivative financial instruments for speculative purposes. The fair value of our foreign currency forward contracts is based on an internally developed model which incorporates observable inputs including quoted spot rates, forward exchange rates and discounted future expected cash flows utilizing market interest rates with similar quality and maturity characteristics. We record the change in fair value of these foreign exchange forward contracts as part of currency gains (losses) within cost of sales in the condensed consolidated statements of income. The fair value of foreign exchange forward contracts are recorded in prepayments and other current assets or other current liabilities in the condensed consolidated balance sheet. The fair value of our foreign exchange forward contracts was a net asset position of $1 million at both September 30, 2016 and December 31, 2015 . The following table summarizes by major currency the notional amounts for foreign currency forward purchase and sale contracts as of September 30, 2016 (all of which mature in 2016): Notional Amount in Foreign Currency (Millions) Australian dollars —Purchase 3 British pounds —Purchase 47 —Sell (45 ) Canadian dollars —Sell (2 ) European euro —Purchase 57 —Sell (121 ) Japanese yen —Purchase 677 —Sell (240 ) Mexican peso —Purchase 280 South African rand —Purchase 137 —Sell (184 ) U.S. dollars —Purchase 193 —Sell (138 ) Guarantees —We have from time to time issued guarantees for the performance of obligations by some of our subsidiaries, and some of our subsidiaries have guaranteed our debt. All of our existing and future material domestic wholly-owned subsidiaries fully and unconditionally guarantee our senior credit facility and our senior notes on a joint and several basis. The arrangement for the senior credit facility is also secured by first-priority liens on substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries. No assets or capital stock secure our senior notes. For additional information, refer to Note 13 of the consolidated financial statements of Tenneco Inc., where we present the Supplemental Guarantor Condensed Consolidating Financial Statements. We have two performance guarantee agreements in the U.K. between Tenneco Management (Europe) Limited (“TMEL”) and the two Walker Group Retirement Plans, the Walker Group Employee Benefit Plan and the Walker Group Executive Retirement Benefit Plan (the “Walker Plans”), whereby TMEL will guarantee the payment of all current and future pension contributions in the event of a payment default by the sponsoring or participating employers of the Walker Plans. The Walker Plans are comprised of employees from Tenneco Walker (U.K.) Limited and our Futaba-Tenneco U.K. joint venture. Employer contributions are funded by both Tenneco Walker (U.K.) Limited, as the sponsoring employer and Futaba-Tenneco U.K., as a participating employer. The performance guarantee agreements are expected to remain in effect until all pension obligations for the Walker Plans’ sponsoring and participating employers have been satisfied. The maximum amount payable for these pension performance guarantees that is not attributable to Tenneco is approximately $10 million as of September 30, 2016 which is determined by taking 105 percent of the liability of the Walker Plans calculated under section 179 of the U.K. Pension Act of 2004 offset by plan assets multiplied by the ownership percent attributable to Futaba-Tenneco U.K. We did not record an additional liability for this performance guarantee since Tenneco Walker (U.K.) Limited, as the sponsoring employer of the Walker Plans, already recognizes 100 percent of the pension obligation calculated based on U.S. GAAP, for all of the Walker Plans’ participating employers on its balance sheet, which was $7 million and $11 million at September 30, 2016 and December 31, 2015 , respectively. At September 30, 2016 , all pension contributions under the Walker Plans were current for all of the Walker Plans’ sponsoring and participating employers. In June 2011, we entered into an indemnity agreement between TMEL and Futaba Industrial Co. Ltd. which requires Futaba to indemnify TMEL for any cost, loss or liability which TMEL may incur under the performance guarantee agreements relating to the Futaba-Tenneco U.K. joint venture. The maximum amount reimbursable by Futaba to TMEL under this indemnity agreement is equal to the amount incurred by TMEL under the performance guarantee agreements multiplied by Futaba’s shareholder ownership percentage of the Futaba-Tenneco U.K. joint venture. At September 30, 2016 , the maximum amount reimbursable by Futaba to TMEL is approximately $10 million . We have issued guarantees through letters of credit in connection with some obligations of our affiliates. As of September 30, 2016 , we have guaranteed $32 million in letters of credit to support some of our subsidiaries’ insurance arrangements, foreign employee benefit programs, environmental remediation activities and cash management and capital requirements. Financial Instruments — One of our European subsidiaries receives payment from one of its customers whereby the accounts receivable are satisfied through the delivery of negotiable financial instruments. We may collect these financial instruments before their maturity date by either selling them at a discount or using them to satisfy accounts receivable that have previously been sold to a European bank. Any of these financial instruments which are not sold are classified as other current assets. Such financial instruments held by our European subsidiary totaled zero and less than $1 million at September 30, 2016 and December 31, 2015 , respectively. In certain instances, several of our Chinese subsidiaries receive payments from customers through the receipt of financial instruments on the date the customer payments are due. Several of our Chinese subsidiaries also satisfy vendor payments through the delivery of financial instruments on the date the payments are due. Financial instruments issued to satisfy vendor payables and not redeemed totaled $22 million and $15 million at September 30, 2016 and December 31, 2015 , respectively, and were classified as notes payable. Financial instruments received from OE customers and not redeemed totaled $14 million and $8 million at September 30, 2016 and December 31, 2015 , respectively. We classify financial instruments received from our customers as other current assets if issued by a financial institution of our customers or as customer notes and accounts, net if issued by our customer. We classified $14 million and $8 million in other current assets at September 30, 2016 and December 31, 2015 , respectively. The financial instruments received by one of our European subsidiaries and some of our Chinese subsidiaries are drafts drawn that are payable at a future date and, in some cases, are negotiable and/or are guaranteed by the banks of the customers. The use of these instruments for payment follows local commercial practice. Because certain of such financial instruments are guaranteed by our customers’ banks, we believe they represent a lower financial risk than the outstanding accounts receivable that they satisfy which are not guaranteed by a bank. Supply Chain Financing — Certain of our suppliers in the U.S. participate in a supply chain financing program under which they securitize their accounts receivables from Tenneco. The financial institution that participates in the supply chain financing program does so on an uncommitted basis and can cease purchasing receivables from Tenneco's suppliers at any time. If the financial institution did not continue to purchase receivables from Tenneco's suppliers under this program, the participating vendors may have a need to renegotiate their payment terms with Tenneco which in turn would cause our borrowings under our revolving credit facility to increase. Restricted Cash - Some of our Chinese subsidiaries that issue their own financial instruments to pay vendors are required to maintain a cash balance if they exceed credit limits with the financial institution that guarantees the financial instruments. A restricted cash balance was required at those Chinese subsidiaries for $2 million and $1 million at September 30, 2016 and December 31, 2015 , respectively.

The arrangement is secured by substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries, as well as guarantees by our material domestic subsidiaries. As of September 30, 2016 , the senior credit facility provides us with a total revolving credit facility size of $1,200 million and had a $274 million balance outstanding under the Tranche A Term Facility, both of which will mature on December 8, 2019 . Net carrying amount for the balance outstanding under the Tranche A Term Facility including a $2 million debt issuance cost was $272 million as of September 30, 2016 . Funds may be borrowed, repaid and re-borrowed under the revolving credit facility without premium or penalty (subject to any customary LIBOR breakage fees). The revolving credit facility is reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. Outstanding letters of credit reduce our availability to borrow revolving loans under the facility. We are required to make quarterly principal payments under the Tranche A Term Facility of $3.75 million through December 31, 2016 , $5.625 million beginning March 31, 2017 through December 31, 2017, $7.5 million beginning March 31, 2018 through September 30, 2019 and a final payment of $195 million is due on December 8, 2019. We have excluded the required payments, within the next twelve months, under the Tranche A Term Facility totaling $21 million from current liabilities as of September 30, 2016 , because we have the intent and ability to refinance the obligations on a long-term basis by using our revolving credit facility. The financial ratios required under the amended and restated senior credit facility, and the actual ratios we achieved for the three quarters of 2016, are as follows: Quarter Ended September 30, 2016 June 30, 2016 March 31, 2016 Required Actual Required Actual Required Actual Leverage Ratio (maximum) 3.50 1.52 3.50 1.45 3.50 1.54 Interest Coverage Ratio (minimum) 2.75 14.26 2.75 13.93 2.75 13.90 The senior credit facility includes a maximum leverage ratio covenant of 3.50 and a minimum interest coverage ratio of 2.75 , in each case through December 8, 2019. At September 30, 2016 , of the $1,200 million available under the revolving credit facility, we had unused borrowing capacity of $891 million with $309 million in outstanding borrowings and no outstanding letters of credit. As of September 30, 2016 , our outstanding debt also included (i) $274 million of a term loan which consisted of a $272 million net carrying amount including a $2 million debt issuance cost related to our Tranche A Term Facility which is subject to quarterly principal payments as described above through December 8, 2019 , (ii) $225 million of notes which consisted of a $221 million net carrying amount including a $4 million debt issuance cost related to our 5 3 / 8 percent senior notes due December 15, 2024 , (iii) $500 million of notes which consisted of a $492 million net carrying amount including a $8 million debt issuance cost related to our 5 percent senior notes due July 15, 2026 (which were issued on June 13, 2016), and (iv) $140 million of other debt. On June 6, 2016, we announced a cash tender offer to purchase our outstanding $500 million 6 7 /8 percent senior notes due in 2020. We received tenders representing $325 million aggregate principal amount of the notes and, on June 13, 2016, we purchased the tendered notes at a price of 103.81 percent of the principal amount, plus accrued and unpaid interest. On July 13, 2016, we redeemed the remaining outstanding $175 million aggregate principal amount of the notes that were not purchased pursuant to the tender offer at a price of 103.438 percent of the principal amount, plus accrued and unpaid interest. We used the proceeds of the issuance of our 5 percent senior notes due 2026 to fund the purchase and redemption. The senior credit facility was used to fund the fees and expenses of the tender offer and redemption. We recorded $16 million and $8 million of pre-tax interest charges in June and July of 2016, respectively, related to the repurchase and redemption of our 6 7 /8 percent senior notes due in 2020 and the write-off of deferred debt issuance costs relating to those notes.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim tax reporting we estimate our annual effective tax rate and apply it to our 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 impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter due to the mix and timing of actual earnings versus annual projections. The tax effects of certain unusual or infrequently occurring 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. We reported income tax benefit of $69 million and tax expense of $34 million in the three month periods ended September 30, 2016 and 2015, respectively. The tax benefit recorded in the third quarter of 2016 included a net tax benefit of $105 million primarily relating to recognizing a U.S. tax benefit for foreign taxes. During the third quarter, we completed our detailed analysis of our ability to recognize and utilize foreign tax credits within the carryforward period. As a result, we amended our U.S. federal tax returns for the years 2006 to 2012 to claim foreign tax credits in lieu of deducting foreign taxes paid. The U.S. foreign tax credit law provides for a credit against U.S. taxes otherwise payable for foreign taxes paid with regard to dividends, interest and royalties paid to us in the U.S. The tax expense recorded in the third quarter of 2015 included a net tax benefit of $12 million primarily relating to tax adjustments to prior year U.S. research and development tax credits. We reported income tax expense of $5 million and $122 million in the nine month periods ended September 30, 2016 and 2015, respectively. The tax expense recorded in the first nine months of 2016 included a net tax benefit of $106 million primarily relating to recognizing a U.S. tax benefit for foreign taxes as described above. The tax expense recorded in the first nine months of 2015 included a net tax benefit of $9 million primarily relating to prior year U.S. research and development tax credits, prior year intercompany transactions and tax adjustments to prior year income tax estimates. We believe it is reasonably possible that up to $22 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.

Accounts Receivable Securitizat

Accounts Receivable Additional Disclosures [Abstract]
Accounts Receivable Securitization	Accounts Receivable Securitization We securitize some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization programs, we are responsible for performing all accounts receivable administration functions for these securitized financial assets including collections and processing of customer invoice adjustments. In the U.S., we have an accounts receivable securitization program with three commercial banks comprised of a first priority facility and a second priority facility. We securitize original equipment and aftermarket receivables on a daily basis under the bank program. In March 2015, the U.S. program was amended and extended to April 30, 2017. The first priority facility provides financing of up to $130 million and the second priority facility, which is subordinated to the first priority facility, provides up to an additional $50 million of financing. Both facilities monetize accounts receivable generated in the U.S. that meet certain eligibility requirements, and the second priority facility also monetizes certain accounts receivable generated in the U.S. that would otherwise be ineligible under the first priority securitization facility. The amount of outstanding third-party investments in our securitized accounts receivable under the U.S. program was $50 million and $30 million at September 30, 2016 and December 31, 2015 , respectively. Each facility contains customary covenants for financings of this type, including restrictions related to liens, payments, mergers or consolidations and amendments to the agreements underlying the receivables pool. Further, each facility may be terminated upon the occurrence of customary events (with customary grace periods, if applicable), including breaches of covenants, failure to maintain certain financial ratios, inaccuracies of representations and warranties, bankruptcy and insolvency events, certain changes in the rate of default or delinquency of the receivables, a change of control and the entry or other enforcement of material judgments. In addition, each facility contains cross-default provisions, where the facility could be terminated in the event of non-payment of other material indebtedness when due and any other event which permits the acceleration of the maturity of material indebtedness. We also securitize receivables in our European operations with regional banks in Europe. The arrangements to securitize receivables in Europe are provided under six separate facilities provided by various financial institutions in each of the foreign jurisdictions. The commitments for these arrangements are generally for one year , but some may be canceled with notice 90 days prior to renewal. In some instances, the arrangement provides for cancellation by the applicable financial institution at any time upon notification. The amount of outstanding third-party investments in our securitized accounts receivable in Europe was $206 million and $174 million at September 30, 2016 and December 31, 2015 , respectively. If we were not able to securitize receivables under either the U.S. or European securitization programs, our borrowings under our revolving credit agreement might increase. These accounts receivable securitization programs provide us with access to cash at costs that are generally favorable to alternative sources of financing, and allow us to reduce borrowings under our revolving credit agreement. In our U.S. accounts receivable securitization programs, we transfer a partial interest in a pool of receivables and the interest that we retain is subordinate to the transferred interest. Accordingly, we account for our U.S. securitization program as a secured borrowing. In our European programs, we transfer accounts receivables in their entirety to the acquiring entities and satisfy all of the conditions established under ASC Topic 860, “Transfers and Servicing,” to report the transfer of financial assets in their entirety as a sale. The fair value of assets received as proceeds in exchange for the transfer of accounts receivable under our European securitization programs approximates the fair value of such receivables. We recognized $1 million interest expense in each of the three month periods ended September 30, 2016 and 2015 , and $2 million in each of the nine month periods ended September 30, 2016 and 2015 , relating to our U.S. securitization program. In addition, we recognized a loss of $1 million in each of the three month periods ended September 30, 2016 and 2015 , and $4 million and $3 million in the nine month periods ended September 30, 2016 and 2015 , respectively, on the sale of trade accounts receivable in our European accounts receivable securitization programs, representing the discount from book values at which these receivables were sold to our banks. The discount rate varies based on funding costs incurred by our banks, which averaged approximately two percent during the first nine months of both 2016 and 2015.

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges	Restructuring and Other Charges Over the past several years, we have adopted plans to restructure portions of our operations. These plans were approved by our Board of Directors and were designed to reduce operational and administrative overhead costs throughout the business. For the full year 2015, we incurred $63 million in restructuring and related costs including asset write-downs of $10 million , primarily related to European cost reduction efforts, exiting the Marzocchi suspension business, headcount reductions in Australia and South America, and the closure of a JIT plant in Australia, of which $46 million was recorded in cost of sales, $11 million in SG&A, $1 million in engineering expense, $1 million in other expense and $4 million in depreciation and amortization expense. In the third quarter of 2016, we incurred $7 million in restructuring and related costs, primarily related to manufacturing footprint improvements in North America Ride Performance as well as headcount reduction and cost improvement initiatives in Europe and China Clean Air, of which $3 million was recorded in cost of sales and $4 million in SG&A. In the third quarter of 2015, we incurred $35 million in restructuring and related costs including asset write-downs of $9 million , primarily related to European cost reduction efforts, exiting the Marzocchi suspension business, and headcount reductions in Australia and South America, of which $27 million was recorded in cost of sales, $3 million in SG&A, $1 million in engineering expense and $4 million in depreciation and amortization expense. In the first nine months of 2016, we incurred $26 million in restructuring and related costs including asset write-downs of $5 million , primarily related to manufacturing footprint improvements in North America Ride Performance as well as headcount reduction and cost improvement initiatives in Europe and China Clean Air and South America, of which $9 million was recorded in cost of sales, $12 million in SG&A, $2 million in other expense and $3 million in depreciation and amortization expense. In the first nine months of 2015, we incurred $47 million in restructuring and related costs including asset write-downs of $9 million , primarily related to European cost reduction efforts, exiting the Marzocchi suspension business, headcount reductions in Australia and South America and the closure of a JIT plant in Australia, of which $37 million was recorded in cost of sales, $5 million in SG&A, $1 million in engineering expense and $4 million in depreciation and amortization expense. Amounts related to activities that are part of our restructuring reserves are as follows: December 31, 2016 2016 Impact of Exchange Rates September 30, 2016 (Millions) Employee Severance, Termination Benefits and Other Related Costs $30 21 (35 ) 1 $17 On January 31, 2013, we announced our intent to reduce structural costs in Europe by approximately $60 million annually. During the first quarter of 2016, we reached an annualized run rate on this cost reduction initiative of $49 million . With the disposition of the Gijon plant, which was completed at the end of the first quarter, the annualized rate essentially reached our target of $55 million , at the current exchange rates. In the third quarter of 2016, we incurred $7 million in restructuring and related costs, of which $1 million was related to this initiative. In the first nine months of 2016, we incurred $26 million in restructuring and related costs, of which $16 million was related to this initiative. While we are nearing the completion of this initiative, we expect to incur additional restructuring and related costs in 2016 due to certain ongoing matters. For example, we closed the Gijon plant in 2013, but subsequently re-opened it in July 2014 with about half of its prior workforce after the employees' works council successfully filed suit challenging the closure decision. Pursuant to an agreement we entered into with employee representatives, we engaged in a sales process for the facility. In March of 2016, we signed an agreement to transfer ownership of the manufacturing facility in Gijon, Spain to German private equity fund Quantum Capital Partners A.G. (QCP). The transfer to QCP was effective March 31, 2016 and under a three year manufacturing agreement, QCP will also continue as a supplier to Tenneco. On July 22, 2015, we announced our intention to discontinue our Marzocchi motorcycle fork suspension product line and our mountain bike suspension product line, and liquidate our Marzocchi operations. These actions were subject to a consultation process with the employee representatives and in total eliminated approximately 138 jobs. We employed 127 people at the Marzocchi plant in Bologna, Italy and an additional 11 people in our operations in North America and Taiwan. In November 2015, we closed on the sale of certain assets related to our Marzocchi mountain bike suspension product line to the affiliates of Fox Factory Holding Corp.; and in December 2015, we closed on the sale of the Marzocchi motorcycle fork product line to an Italian company, VRM S.p.A. These actions were a part of our ongoing efforts to optimize our Ride Performance product line globally while continuously improving our operations and increasing profitability. We recorded charges of $29 million in 2015 related to severance and other employee related costs, asset write-downs and other expenses related to these sales. Under the terms of our amended and restated senior credit agreement that took effect on December 8, 2014, we are allowed to exclude up to $150 million in the aggregate of all costs, expenses, fees, fines, penalties, judgments, legal settlements and other amounts associated with any restructuring, litigation, claim, proceeding or investigation related to or undertaken by us or any of our subsidiaries, together with any related provision for taxes, incurred after December 8, 2014 in the calculation of the financial covenant ratios required under our senior credit facility. As of September 30, 2016 , we had excluded $74 million of allowable charges relating to restructuring initiatives against the $150 million available under the terms of the senior credit facility.

Environmental Matters, Litigati

Environmental Matters, Litigation and Product Warranties [Abstract]
Environmental Matters, Litigation and Product Warranties	Environmental Matters, Legal Proceedings and Product Warranties We are involved in environmental remediation matters, legal proceedings, claims, investigations and warranty obligations. These matters are typically incidental to the conduct of our business and create the potential for contingent losses. We accrue for potential contingent losses when our review of available facts indicates that it is probable a loss has been incurred and the amount of the loss is reasonably estimable. Each quarter we assess our loss contingencies based upon currently available facts, existing technology, presently enacted laws and regulations and taking into consideration the likely effects of inflation and other societal and economic factors and record adjustments to these reserves as required. As an example, we consider all available evidence, including prior experience in remediation of contaminated sites, other companies’ cleanup experiences and data released by the United States Environmental Protection Agency or other organizations when we evaluate our environmental remediation contingencies. All of our loss contingency estimates are subject to revision in future periods based on actual costs or new information. With respect to our environmental liabilities, where future cash flows are fixed or reliably determinable, we have discounted those liabilities. We evaluate recoveries separately from the liability and, when they are assured, recoveries are recorded and reported separately from the associated liability in our consolidated financial statements. Environmental Matters We are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to current operations. We expense costs related to an existing condition caused by past operations that do not contribute to current or future revenue generation. As of September 30, 2016 , we have the obligation to remediate or contribute towards the remediation of certain sites, including one Federal Superfund site. At September 30, 2016 , our aggregated estimated share of environmental remediation costs for all these sites on a discounted basis was approximately $16 million , of which $2 million is recorded in other current liabilities and $14 million is recorded in deferred credits and other liabilities in our condensed consolidated balance sheet. For those locations where the liability was discounted, the weighted average discount rate used was 1.7 percent . The undiscounted value of the estimated remediation costs was $19 million . Our expected payments of environmental remediation costs are estimated to be approximately $1 million in 2016, $2 million in 2017, $1 million in each year beginning 2018 through 2020 and $13 million in aggregate thereafter. Based on information known to us, we have established reserves that we believe are adequate for these costs. Although we believe these estimates of remediation costs are reasonable and are based on the latest available information, the costs are estimates and are subject to revision as more information becomes available about the extent of remediation required. At some sites, we expect that other parties will contribute to the remediation costs. In addition, certain environmental statutes provide that our liability could be joint and several, meaning that we could be required to pay in excess of our share of remediation costs. Our understanding of the financial strength of other potentially responsible parties at these sites has been considered, where appropriate, in our determination of our estimated liability. We do not believe that any potential costs associated with our current status as a potentially responsible party in the Federal Superfund site, or as a liable party at the other locations referenced herein, will be material to our consolidated financial position, results of operations, or liquidity. Antitrust Investigations and Litigation On March 25, 2014, representatives of the European Commission 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 March 25, 2014, we also received a related subpoena from the U.S. Department of Justice ("DOJ"). On November 5, 2014, the DOJ granted us conditional leniency pursuant to an agreement we entered into under the Antitrust Division's Corporate Leniency Policy. This agreement provides us with important benefits in exchange for our self-reporting of matters to the DOJ and our continuing full cooperation with the DOJ's resulting investigation. For example, the DOJ will not bring any criminal antitrust prosecution against us, nor seek any criminal fines or penalties, in connection with the matters we reported to the DOJ. Additionally, there are limits on our liability related to any follow on civil antitrust litigation in the U.S. 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 our satisfying the DOJ and any court presiding over such follow on civil litigation. Certain other competition agencies are also investigating possible violations of antitrust laws relating to products supplied by our company. We have cooperated and continue to cooperate fully with all of these antitrust investigations, and take other actions to minimize our potential exposure. Tenneco and certain of its competitors are also currently defendants in civil putative class action litigation in the United States. 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 we received conditional leniency from the DOJ, our civil liability in these follow on actions is limited to single damages and we will not be jointly and severally liable with the other defendants, provided that we have satisfied our obligations under the DOJ leniency agreement and approval is granted by the presiding court. Antitrust law investigations, civil litigation, and related matters often continue for several years and can result in significant penalties and liability. We intend to vigorously defend the company and/or take other actions to minimize our potential exposure. In light of the many uncertainties and variables involved, we cannot estimate the ultimate impact that these matters may have on our company. Further, there can be no assurance that the ultimate resolution of these matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity. Other Legal Proceedings, Claims and Investigations We are also from time to time involved in other legal proceedings, claims or investigations. Some of these matters involve allegations of damages against us 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, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. Additionally, some of these matters involve allegations relating to legal compliance. For example, in the U.S. we are subject to an audit in 11 states with respect to the payment of unclaimed property to those states, spanning a period as far back as over 30 years . While we vigorously defend ourselves against all of these legal proceedings, claims and investigations and take other actions to minimize our potential exposure, in future periods, we 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 our assessment of the merits of the particular claim, except as described above under "Antitrust Investigations," we do not expect the legal proceedings, claims or investigations currently pending against us will have any material adverse impact on our consolidated financial position, results of operations or liquidity. In addition, for many years we have been and continue to be subject to lawsuits initiated by claimants alleging health problems as a result of exposure to asbestos. Our current docket of active and inactive cases is less than 500 cases nationwide. A small number of claims have been asserted against one of our subsidiaries by railroad workers alleging exposure to asbestos products in railroad cars. The substantial majority of the remaining claims are related to alleged exposure to asbestos in our automotive products although a significant number of those claims appear also to involve occupational exposures sustained in industries other than automotive. We believe, based on scientific and other evidence, it is unlikely that claimants were exposed to asbestos by our 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, with the number in some cases exceeding 100 defendants from a variety of industries. Additionally, in many cases the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. As major asbestos manufacturers and/or users continue to go out of business or file for bankruptcy, we may experience an increased number of these claims. We vigorously defend ourselves against these claims as part of our ordinary course of business. In future periods, we could be subject to cash costs or charges to earnings if any of these matters are resolved unfavorably to us. To date, with respect to claims that have proceeded sufficiently through the judicial process, we have regularly achieved favorable resolutions. Accordingly, we presently believe that these asbestos-related claims will not have a material adverse impact on our future consolidated financial position, results of operations or liquidity. Warranty Matters We provide warranties on some of our products. The warranty terms vary but range from one year up to limited lifetime warranties on some of our 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 our products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims. We actively study trends of our warranty claims and take action to improve product quality and minimize warranty claims. We believe that 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 balance sheet. Below is a table that shows the activity in the warranty accrual accounts: Nine Months Ended September 30, 2016 2015 (Millions) Beginning Balance January 1, $ 23 $ 26 Accruals related to product warranties 6 11 Reductions for payments made (10 ) (13 ) Ending Balance September 30, $ 19 $ 24

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Common Stock	Common Stock Equity Plans — We have granted a variety of awards, including common stock, restricted stock, restricted stock units, performance units, stock appreciation rights (“SARs”), and stock options to our directors, officers, and employees. Accounting Methods — We recorded compensation expense (net of taxes) of less than $1 million in the three month period ended September 30, 2016 and $1 million in the three month period ended September 30, 2015 and $1 million and $3 million in compensation expense for the nine month periods ended September 30, 2016 and 2015, respectfully, related to nonqualified stock options as part of our selling, general and administrative expense. This had no impact on basic or diluted earnings per share for each of the three month periods ended September 30, 2016 and resulted in a decrease of $0.01 in both basic and diluted earnings per share for the nine month periods ended September 30, 2016 and 2015. For employees eligible to retire at the grant date, we immediately expense stock options and restricted stock. If employees become eligible to retire during the vesting period, we immediately recognize any remaining expense associated with their stock options and restricted stock. As of September 30, 2016 , there was less than $1 million of unrecognized compensation costs related to our stock option awards that we expect to recognize over a weighted average period of 0.3 years. Compensation expense for restricted stock, restricted stock units, long-term performance units and SARs (net of taxes) was $5 million and $1 million for the three month periods ended September 30, 2016 and 2015, respectively, and $14 million and $10 million for the nine month periods ended September 30, 2016 and 2015, respectively, and was recorded in selling, general, and administrative expense in our condensed consolidated statements of income. Cash received from stock option exercises for the nine month periods ended September 30, 2016 and 2015 was $4 million and $1 million , respectively. Stock options exercised in the first nine months of 2016 and 2015 generated a tax benefit of $1 million and $6 million , respectively. We started to record this tax effect in the third quarter of 2013 when we began utilizing our federal and state NOLs.

The total fair value of restricted shares vested was $9 million and $6 million at September 30, 2016 and 2015, respectively. In January 2015, our Board of Directors approved a share repurchase program, authorizing our company to repurchase up to $350 million of our outstanding common stock over a three year period. This repurchase program does not obligate Tenneco to make repurchases at any specific time or situation and is part of our overall capital allocation strategy. In October 2015, our Board of Directors expanded our company's share repurchase plan, authorizing the repurchase of an additional $200 million of our company's outstanding common stock. This authorization is in addition to the $350 million share repurchase program our company announced in January 2015. We repurchased 2.8 million shares for $146 million through this program in the nine months ended September 30, 2016 . Since we announced the current share repurchase program in January 2015, we have repurchased 7.0 million shares for $359 million through September 30, 2016 . Treasury stock shares including repurchased shares were 10,256,389 and 7,473,325 shares at September 30, 2016 and December 31, 2015 , respectively. Long-Term Performance Units, Restricted Stock Units and SARs — Long-term performance units, restricted stock units and SARs are paid in cash and recognized as a liability based upon their fair value. As of September 30, 2016 , $21 million of total unrecognized compensation costs is expected to be recognized over a weighted-average period of approximately 1.0 years.

Based on current actuarial estimates, we believe we will be required to contribute approximately $32 million for the remainder of 2016 , which includes estimated contributions for the pension buyout referenced below. Pension contributions beyond 2016 will be required, but those amounts will vary based upon many factors including, for example, the performance of our pension fund investments during 2016 . In February 2016, the Company launched a voluntary program to buy out active employees and retirees who have earned benefits in the U.S. pension plans and announced that the program is expected to be completed by the end of 2016. We will record a non-cash charge at that time. Cash payments to those who elect to take the buyout will be made from pension plan assets. We made postretirement contributions of approximately $6 million during the first nine months of 2016 . Based on current actuarial estimates, we believe we will be required to contribute approximately $3 million for the remainder of 2016 . The assets of some of our pension plans are invested in trusts that permit commingling of the assets of more than one employee benefit plan for investment and administrative purposes. Each of the plans participating in the trust has interests in the net assets of the underlying investment pools of the trusts. The investments for all our pension plans are recorded at estimated fair value, in compliance with the accounting guidance on fair value measurement. Amounts recognized for pension and postretirement benefits in other comprehensive income for the three and nine months ended September 30, 2016 and 2015 include the following components: Three Months Ended September 30, 2016 2015 Before-Tax Amount Tax Benefit Net-of-Tax Amount Before- Tax Amount Tax Benefit Net-of-Tax Amount (Millions) Defined benefit pension and postretirement plans: Amortization of actuarial loss included in net periodic pension and postretirement cost 5 (1 ) 4 6 (2 ) 4 Other comprehensive income – pension benefits $ 5 $ (1 ) $ 4 $ 6 $ (2 ) $ 4 Nine Months Ended September 30, 2016 2015 Before-Tax Tax Net-of-Tax Before- Tax Net-of-Tax (Millions) Defined benefit pension and postretirement plans: Amortization of prior service cost included in net periodic pension and postretirement cost $ — $ — $ — $ (2 ) $ — $ (2 ) Amortization of actuarial loss included in net periodic pension and postretirement cost 15 (4 ) 11 15 (4 ) 11 Other comprehensive income – pension benefits $ 15 $ (4 ) $ 11 $ 13 $ (4 ) $ 9

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued Accounting Standard Update 2016-02, Leases (Topic 842). The amendments in this update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for 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 flow 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. We will adopt this amendment on January 1, 2019. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements. In May 2015, the FASB issued Accounting Standard Update (ASU) No. 2015-07, Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent). ASU No. 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. Such investments should be disclosed separate from the fair value hierarchy. For public business entities, the standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company's consolidated financial statements but will impact pension asset disclosure in our annual report on Form 10-K going forward. In May 2014, the FASB issued an amendment on revenue recognition. The amendment in this update creates Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB has voted to approve a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017 for public entities. We will adopt this amendment on January 1, 2018. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements.

Segment Reporting [Abstract]
Segment Information	Segment Information We are organized and manage our business along our two major product lines (clean air and ride performance) and three geographic areas (North America; Europe, South America and India; and Asia Pacific), resulting in six operating segments (North America Clean Air, North America Ride Performance, Europe, South America and India Clean Air, Europe, South America and India Ride Performance, Asia Pacific Clean Air and Asia Pacific Ride Performance). Within each geographical area, each operating segment manufactures and distributes either clean air or ride performance products primarily for the original equipment and aftermarket industries. Each of the six operating segments constitutes a reportable segment. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the six operating segments as "Other." We evaluate segment performance based primarily on earnings before interest expense, income taxes, and noncontrolling interests. Products are transferred between segments and geographic areas on a basis intended to reflect as nearly as possible the “market value” of the products. The following table summarizes certain Tenneco Inc. segment information: Clean Air Division Ride Performance Division North America Europe, South America & India Asia Pacific North America Europe, South America & India Asia Pacific Other Reclass & Elims Total (Millions) At September 30, 2016 and for the Three Months Ended September 30, 2016 Revenues from external customers $ 716 $ 487 $ 257 $ 306 $ 258 $ 72 $ — $ — $ 2,096 Intersegment revenues 4 24 1 2 6 12 — (49 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 44 30 37 37 11 15 (22 ) — 152 Total assets 1,390 842 593 727 564 243 — 47 4,406 At September 30, 2015 and for the Three Months Ended September 30, 2015 Revenues from external customers 720 453 235 330 236 51 — — 2,025 Intersegment revenues 4 27 — 3 7 12 — (53 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 58 14 31 39 (21 ) 9 (14 ) — 116 Total assets 1,292 775 532 768 557 200 — 33 4,157 At September 30, 2016 and for the Nine Months Ended September 30, 2016 Revenues from external customers $ 2,252 $ 1,498 $ 777 $ 952 $ 771 $ 194 $ — $ — $ 6,444 Intersegment revenues 9 70 2 6 21 35 — (143 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 172 75 109 127 19 38 (87 ) — 453 Total assets 1,390 842 593 727 564 243 — 47 4,406 At September 30, 2015 and for the Nine Months Ended September 30, 2015 Revenues from external customers 2,150 1,381 743 1,021 718 165 — — 6,178 Intersegment revenues 11 79 — 8 22 37 — (157 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 179 36 86 125 (1 ) 27 (61 ) — 391 Total assets 1,292 775 532 768 557 200 — 33 4,157

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued Accounting Standard Update 2016-02, Leases (Topic 842). The amendments in this update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for 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 flow 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. We will adopt this amendment on January 1, 2019. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements. In May 2015, the FASB issued Accounting Standard Update (ASU) No. 2015-07, Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent). ASU No. 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. Such investments should be disclosed separate from the fair value hierarchy. For public business entities, the standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company's consolidated financial statements but will impact pension asset disclosure in our annual report on Form 10-K going forward. In May 2014, the FASB issued an amendment on revenue recognition. The amendment in this update creates Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB has voted to approve a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017 for public entities. We will adopt this amendment on January 1, 2018. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements.
