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, 2014 . 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.

Fair Value Disclosures [Abstract]
Financial Instruments	Financial Instruments The net carrying and estimated fair values of our financial instruments by class at June 30, 2015 and December 31, 2014 were as follows: June 30, 2015 December 31, 2014 Net Carrying Amount Fair Value Net Carrying Amount Fair Value (Millions) Long-term debt (including current maturities) $ 1,104 $ 1,146 $ 1,057 $ 1,106 Instruments with off-balance sheet risk: Foreign exchange forward contracts: Asset derivative contracts — — — — 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 $754 million and $759 million at June 30, 2015 and December 31, 2014 , respectively. We have classified $360 million and $301 million as level 2 in the fair value hierarchy at June 30, 2015 and December 31, 2014 , respectively, since we use valuation inputs that are observable both directly and indirectly. We classified the remaining $32 million and $46 million , consisting of foreign subsidiary debt, as level 3 in the fair value hierarchy at June 30, 2015 and December 31, 2014 , 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 — 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 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 liability position of less than $1 million at both June 30, 2015 and December 31, 2014 . The following table summarizes by major currency the notional amounts for foreign currency forward purchase and sale contracts as of June 30, 2015 (all of which mature in 2015): Notional Amount in Foreign Currency (Millions) Australian dollars —Purchase 1 —Sell (1 ) British pounds —Purchase 10 —Sell (25 ) Canadian dollars —Sell (6 ) European euro —Purchase 7 —Sell (10 ) South African rand —Purchase 112 Japanese yen —Purchase 228 —Sell (604 ) U.S. dollars —Purchase 60 —Sell (35 ) Other —Purchase 1 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 our condensed consolidated financial statements, 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 $7 million as of June 30, 2015 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 multiply by 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 $15 million and $17 million at June 30, 2015 and December 31, 2014 , respectively. At June 30, 2015 , 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 June 30, 2015 , the maximum amount reimbursable by Futaba to TMEL is approximately $7 million . We have issued letters of credit in connection with some obligations of our affiliates. As of June 30, 2015 , we have issued $38 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 early delivery of 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. The amount of these financial instruments that was collected before their maturity date and sold at a discount totaled $1 million at both June 30, 2015 and December 31, 2014 . No such financial instruments were held by our European subsidiary as of June 30, 2015 or December 31, 2014 . 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 $32 million and $24 million at June 30, 2015 and December 31, 2014 , respectively, and were classified as notes payable. Financial instruments received from OE customers and not redeemed totaled $19 million and $17 million at June 30, 2015 and December 31, 2014 , 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 $19 million and $17 million in other current assets at June 30, 2015 and December 31, 2014 , 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 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 — Near the end of the second quarter of 2013 certain of our suppliers in the U.S. extended their payment terms to Tenneco. The liquidity benefit to Tenneco from the extended payment terms totaled $12 million at June 30, 2015 . These suppliers also began participating in a supply chain financing program under which they securitize their accounts receivables from Tenneco with two financial institutions. The financial institutions participate in the supply chain financing program on an uncommitted basis and can cease purchasing receivables from Tenneco's suppliers at any time. If the financial institutions did not continue to purchase receivables from Tenneco's suppliers under this program, the participating vendors could reduce their payment terms to 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 at June 30, 2015 for $2 million and was not required at December 31, 2014 .

Debt Disclosure [Abstract]
Long-Term Debt and Financing Arrangements	Long-Term Debt and Financing Arrangements Our financing arrangements are primarily provided by a committed senior secured financing arrangement with a syndicate of banks and other financial institutions. 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. In April 2015, the FASB issued Accounting Standard Update 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. 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. Early adoption of the amendments in this update is permitted for financial statements that have not been previously issued. We adopted this standard for the first quarter of 2015 and applied retrospectively. The balance for unamortized debt issuance costs was $13 million and $14 million at June 30, 2015 and December 31, 2014 , respectively. On December 8, 2014, we completed an amendment and restatement of our senior credit facility by increasing the amount and extending the maturity dates of our revolving credit facility and our Tranche A Term Facility. As of June 30, 2015 , the senior credit facility provides us with a total revolving credit facility size of $1,200 million and had a $293 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 $291 million as of June 30, 2015 . 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 $15 million from current liabilities as of June 30, 2015 , 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 two quarters of 2015, are as follows: Quarter Ended June 30, 2015 March 31, 2015 Required Actual Required Actual Leverage Ratio (maximum) 3.50 1.36 3.50 1.41 Interest Coverage Ratio (minimum) 2.75 12.43 2.75 11.95 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 June 30, 2015 , of the $1,200 million available under the revolving credit facility, we had unused borrowing capacity of $1,099 million with $67 million in outstanding borrowings and $34 million in outstanding letters of credit. As of June 30, 2015 , our outstanding debt also included (i) $293 million of a term loan which consisted of a $291 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 of 5 3 /8 percent senior notes due December 15, 2024 , (iii) $500 million of notes which consisted of a $493 million net carrying amount including a $7 million debt issuance cost of 6 7 /8 percent senior notes due December 15, 2020 , and (iv) $158 million of other debt.

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 expense of $47 million and $46 million in the three month periods ended June 30, 2015 and 2014, respectively. The tax expense recorded in the second quarter of 2015 included a net tax expense of $2 million primarily relating to prior year intercompany transactions and tax adjustments to prior year income tax estimates. We reported income tax expense of $88 million and $86 million in the six month periods ended June 30, 2015 and 2014, respectively. The tax expense recorded in the first six months of 2015 included $3 million primarily relating to prior year intercompany transactions and tax adjustments to prior year income tax estimates. The tax expense recorded in the first six months of 2014 included a net tax benefit of $1 million for tax adjustments primarily relating to changes to uncertain tax positions and prior year income tax estimates. We believe it is reasonably possible that up to $6 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 coming year.

Accounts Receivable Additional Disclosures [Abstract]
Accounts Receivable Securitization	Accounts Receivable Securitization We securitize some of our accounts receivable on a limited recourse basis in North America 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 North America, 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 North American 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. and Canada that meet certain eligibility requirements, and the second priority facility also monetizes certain accounts receivable generated in the U.S. and Canada 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 North American program was $50 million at June 30, 2015 and zero at December 31, 2014 . 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 $187 million and $153 million at June 30, 2015 and December 31, 2014 , respectively. If we were not able to securitize receivables under either the North American 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 North American 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 North American 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 less than $1 million interest expense in each of the three month periods ended June 30, 2015 and 2014 , and $1 million in each of the six month periods ended June 30, 2015 and 2014, relating to our North American securitization program. In addition, we recognized a loss of $1 million in each of the three month periods ended June 30, 2015 and 2014 , and $2 million in each of the six month periods ended June 30, 2015 and 2014 , 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 both the first half of 2015 and 2014, respectively.

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 2014, we incurred $49 million in restructuring and related costs including non-cash charges of $5 million , primarily related to European cost reduction efforts, headcount reductions in Australia and South America, the sale of a closed facility in Cozad, Nebraska and costs related to organizational changes, of which $28 million was recorded in cost of sales, $9 million in SG&A, $7 million in engineering expense, $4 million in other expense and $1 million in depreciation and amortization. In the second quarter of 2015, we incurred $7 million in restructuring and related costs, primarily related to European cost reduction efforts and headcount reductions in South America, of which $6 million was recorded in cost of sales and $1 million in SG&A. In the second quarter of 2014, we incurred $10 million in restructuring and related costs, primarily related to European cost reduction efforts and headcount reductions in Australia and South America, of which $5 million was recorded in cost of sales, $3 million in SG&A, $1 million in engineering expense and $1 million in other expense. In the first six months of 2015, we incurred $12 million in restructuring and related costs, primarily related to European cost reduction efforts, headcount reductions in South America and the closure of a JIT plant in Australia, of which $10 million was recorded in cost of sales, $2 million in SG&A. In the first six months of 2014, we incurred $20 million in restructuring and related costs, primarily related to European cost reduction efforts including non-cash asset write downs of $1 million and headcount reductions in Australia and South America, of which $15 million was recorded in cost of sales, $3 million in SG&A, $1 million was recorded in engineering expense and $1 million was recorded in other expense. Amounts related to activities that are part of our restructuring reserves are as follows: December 31, 2015 2015 Impact of Exchange Rates June 30, 2015 (Millions) Employee Severance, Termination Benefits and Other Related Costs $40 12 (19 ) (3 ) $30 On January 31, 2013, we announced our intent to reduce structural costs in Europe by approximately $60 million annually. We still expect to reach our target annual savings rate in 2016, however the recent dramatic changes in exchange rates will likely have an impact on the actual savings achieved when translated from Euros into U.S. dollars. In the second quarter of 2015, we incurred $7 million in restructuring and related costs, of which $3 million was related to this initiative. In the first six months of 2015, we incurred $12 million in restructuring and related costs, of which $7 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 2015 and 2016 due to certain ongoing matters. For example, we closed a plant in Gijon Spain 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 are currently engaged in a sales process for the facility and intend to continue operating it until a complete transfer of ownership takes place in 2016.

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 June 30, 2015 , we have the obligation to remediate or contribute towards the remediation of certain sites, including one Federal Superfund site. At June 30, 2015 , our aggregated estimated share of environmental remediation costs for all these sites on a discounted basis was approximately $14 million , of which $2 million is recorded in other current liabilities and $12 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 2.2 percent . The undiscounted value of the estimated remediation costs was $17 million . Our expected payments of environmental remediation costs are estimated to be approximately $2 million in 2015, $1 million each year beginning 2016 through 2019 and $11 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 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. We cannot provide any assurance as to when such actions will be filed in the future or how they will ultimately be resolved. 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. Antitrust law investigations and related matters often continue for several years and can result in significant penalties and liability. At this point, we cannot estimate the ultimate impact on our company from investigations into our antitrust compliance and related matters in light of the uncertainties and many variables involved, and there can be no assurance that the ultimate resolution of these matters, including any civil litigation claims, 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, one of our Argentine subsidiaries is currently defending against a criminal complaint alleging the failure to comply with laws requiring the proceeds of export transactions to be collected, reported and/or converted to local currency within specified time periods. As another 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, we are subject to lawsuits initiated by a significant number of claimants alleging health problems as a result of exposure to asbestos. In the early 2000's we were named in nearly 20,000 complaints, most of which were filed in Mississippi state court and the vast majority of which made no allegations of exposure to asbestos from our product categories. Most of these claims have been dismissed and 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 to involve workers in industries that are not automotive-related or otherwise do not include sufficient information to determine whether there is any basis for a claim against us. 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, 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 on OE 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: Six Months Ended June 30, 2015 2014 (Millions) Beginning Balance January 1, $ 26 $ 24 Accruals related to product warranties 6 12 Reductions for payments made (7 ) (10 ) Ending Balance June 30, $ 25 $ 26

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 and $1 million in the three month periods ended June 30, 2015 and 2014 and $1 million and $3 million in compensation expense for each of the six month periods ended June 30, 2015 and 2014, related to nonqualified stock options as part of our selling, general and administrative expense. This resulted in a decrease of $0.01 in both basic and diluted earnings per share for each of the three month periods ended June 30, 2015 and 2014 and a decrease of $0.02 and $0.04 in both basic and diluted earnings per share for the six month period ended June 30, 2015 and 2014. 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 June 30, 2015 , there was approximately $4 million of unrecognized compensation costs related to our stock option awards that we expect to recognize over a weighted average period of 0.7 years. Compensation expense for restricted stock, restricted stock units, long-term performance units and SARs (net of taxes) was $4 million and $5 million for the three month periods ended June 30, 2015 and 2014 and $10 million for each of the six month periods ended June 30, 2015 and 2014, and was recorded in selling, general, and administrative expense in our condensed consolidated statements of income. Cash received from stock option exercises for the six months ended June 30, 2015 and 2014 was $4 million and $1 million , respectively. Stock options exercised in the first six months of 2015 and 2014 generated a tax benefit of $6 million and $3 million , respectively. We started to record this tax benefit in the third quarter of 2013 when we began utilizing our federal and state NOLs. Assumptions — We calculated the fair values of stock option awards using the Black-Scholes option pricing model with the weighted average assumptions listed below. The fair value of share-based awards is determined at the time the awards are granted which is generally in January of each year, and requires judgment in estimating employee and market behavior. There were no stock options granted in 2015. Six Months Ended June 30, 2015 2014 Stock Options Granted Weighted average grant date fair value, per share $ — $ 26.46 Weighted average assumptions used: Expected volatility — % 52.8 % Expected lives 5.0 Risk-free interest rates — % 1.7 % Dividend yields — % — % Expected volatility is calculated based on current implied volatility and historical realized volatility for the Company. Expected lives of options are based upon the historical and expected time to post-vesting forfeiture and exercise. We believe this method is the best estimate of the future exercise patterns currently available. The risk-free interest rates are based upon the Constant Maturity Rates provided by the U.S. Treasury. For our valuations, we used the continuous rate with a term equal to the expected life of the options. Stock Options — The following table reflects the status and activity for all options to purchase common stock for the period indicated: Six Months Ended June 30, 2015 Shares Under Option Weighted Avg.

There were no stock options granted in 2015. The total fair value of shares vested was $4 million and $6 million for the periods ended June 30, 2015 and 2014, respectively. Restricted Stock — The following table reflects the status for all nonvested restricted shares for the period indicated: Six Months Ended June 30, 2015 Shares Weighted Avg.

As of June 30, 2015 , approximately $18 million of total unrecognized compensation costs related to restricted stock awards is expected to be recognized over a weighted-average period of approximately 2.7 years. The total fair value of restricted shares vested was $6 million and $7 million at June 30, 2015 and 2014, 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. We repurchased 748,000 shares through this program in the six months ended June 30, 2015 . Repurchased shares held as part of our treasury stock were 3,992,692 and 3,244,692 shares at June 30, 2015 and December 31, 2014 , 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 June 30, 2015 , $26 million of total unrecognized compensation costs is expected to be recognized over a weighted-average period of approximately 2.0 years.

Based on current actuarial estimates, we believe we will be required to contribute approximately $19 million for the remainder of 2015 . Pension contributions beyond 2015 will be required, but those amounts will vary based upon many factors including, for example, the performance of our pension fund investments during 2015 . We made postretirement contributions of approximately $5 million during the first six months of 2015 . Based on current actuarial estimates, we believe we will be required to contribute approximately $4 million for the remainder of 2015 . 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 six months periods ended June 30, 2015 and 2014 include the following components: Three Months Ended June 30, 2015 2014 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 prior service cost included in net periodic pension and postretirement cost $ (1 ) $ — $ (1 ) $ (2 ) $ — $ (2 ) Amortization of actuarial loss included in net periodic pension and postretirement cost 4 (1 ) 3 5 — 5 Other comprehensive income – pension benefits $ 3 $ (1 ) $ 2 $ 3 $ — $ 3 Six Months Ended June 30, 2015 2014 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 ) $ (2 ) $ — $ (2 ) Amortization of actuarial loss included in net periodic pension and postretirement cost 9 (2 ) 7 9 (1 ) 8 Other comprehensive income – pension benefits $ 7 $ (2 ) $ 5 $ 7 $ (1 ) $ 6

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“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. In April 2015, the FASB issued Accounting Standard Update 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. 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. Early adoption of the amendments in this update is permitted for financial statements that have not been previously issued. We adopted this standard for the first quarter of 2015 and applied retrospectively. Please refer to note 3 in our notes to condensed consolidated financial statements located in Part I Item 1 of this Form 10-Q for further discussion.

Segment Reporting [Abstract]
Segment Information	Segment Information We are managed and organized 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 June 30, 2015 and for the Three Months Ended June 30, 2015 Revenues from external customers $ 746 $ 471 $ 244 $ 360 $ 252 $ 57 $ — $ — $ 2,130 Intersegment revenues 3 25 — 3 9 12 — (52 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 67 12 28 51 12 8 (23 ) — 155 Total assets 1,283 830 566 752 510 227 — 33 4,201 At June 30, 2014 and for the Three Months Ended June 30, 2014 Revenues from external customers 755 523 263 364 280 56 — — 2,241 Intersegment revenues 7 28 — 3 11 11 — (60 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 74 18 23 48 14 8 (29 ) — 156 Total assets 1,230 946 589 714 558 233 — 35 4,305 At June 30, 2015 and for the Six Months Ended June 30, 2015 Revenues from external customers $ 1,430 $ 928 $ 508 $ 691 $ 482 $ 114 $ — $ — $ 4,153 Intersegment revenues 7 52 — 5 15 25 — (104 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 121 22 55 86 20 18 (47 ) — 275 Total assets 1,283 830 566 752 510 227 — 33 4,201 At June 30, 2014 and for the Six Months Ended June 30, 2014 Revenues from external customers 1,453 1,029 503 699 543 108 — — 4,335 Intersegment revenues 14 58 — 6 21 19 — (118 ) — EBIT, Earnings (loss) before interest expense, income taxes, and noncontrolling interests 130 27 43 78 30 15 (54 ) — 269 Total assets 1,230 946 589 714 558 233 — 35 4,305

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“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. In April 2015, the FASB issued Accounting Standard Update 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. 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. Early adoption of the amendments in this update is permitted for financial statements that have not been previously issued. We adopted this standard for the first quarter of 2015 and applied retrospectively. Please refer to note 3 in our notes to condensed consolidated financial statements located in Part I Item 1 of this Form 10-Q for further discussion.
