Over time, the internal planar zirconia ceramic elements suffer micro-cracking and chemical poisoning. This degrades sensor response times, causing false lean or rich biases that send erroneous voltage signals to the ECM. Consequently, the ECU commands poor air-fuel ratios, leading to unburned hydrocarbons overheating the catalytic converters, reduced fuel economy, sluggish throttle tip-in, and persistent CEL illumination (such as P0135, P0141, P0420, or P0430).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement oxygen sensor kit utilizes premium planar ceramic sensing elements insulated inside high-grade 310 stainless steel outer shields to resist high-exhaust temperature oxidation and chemical contamination. Fast-light-off internal ceramic heaters rapidly establish operational temperature, allowing the ECM to enter closed-loop calibration instantly upon startup. Each direct-fit pigtail harness features factory-spec weather-pack connectors with high-temp PTFE lead wire insulation, resisting harness degradation and ensuring stable millivolt feedback signal transmission without wire splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4PCS Upstream + Downstream Oxygen Sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2012-2017 Chevrolet Caprice,Traverse\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e3.6L High Feature V6 (LFX \/ LLT)\u003c\/strong\u003e \/ \u003cstrong\u003eWM, WN \/ Lambda\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e281-305 hp \/ 266-264 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eS4-4565\u003c\/strong\u003e, \u003cstrong\u003e234-4566\u003c\/strong\u003e, \u003cstrong\u003e12590035\u003c\/strong\u003e, \u003cstrong\u003e12597449\u003c\/strong\u003e, \u003cstrong\u003e12616203\u003c\/strong\u003e, \u003cstrong\u003e12634064\u003c\/strong\u003e, \u003cstrong\u003e2344818\u003c\/strong\u003e, \u003cstrong\u003e12596688\u003c\/strong\u003e, \u003cstrong\u003e12634085\u003c\/strong\u003e, \u003cstrong\u003e12640453\u003c\/strong\u003e, \u003cstrong\u003e1821378J10\u003c\/strong\u003e, \u003cstrong\u003e2344259\u003c\/strong\u003e, \u003cstrong\u003e2344840\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2012-2017 Chevrolet Caprice PPV (3.6L V6)\u003c\/li\u003e\n  \u003cli\u003e2012-2017 Chevrolet Traverse LS, LT, LTZ, Premier (3.6L V6)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the WM, WN \/ Lambda Caprice,Traverse?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2012-2017 Chevrolet Caprice and Traverse equipped with the \u003cstrong\u003e3.6L V6\u003c\/strong\u003e engine. \u003cstrong\u003eConfirm engine displacement before ordering; this kit does not fit 6.0L V8 Caprice PPV models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo these sensors require anti-seize during installation?\u003c\/h4\u003e\n\u003cp\u003eThese direct-fit sensors include factory-applied anti-seize on the threads; do not apply excessive anti-seize to avoid contaminating the ceramic sensor tip.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle long idling cycles and heavy-duty operation, these precision sensors maintain accurate air-fuel ratio management across both fleet duty cycles and daily highway towing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551492899064,"sku":"DS-ERQ44IX84","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-chevrolet-caprice-traverse-2012-2017-3-6l-1.jpg?v=1790797390","url":"https:\/\/performancechiptuning.com\/de\/products\/o2-oxygen-sensor-upstream-downstream-for-chevrolet-caprice-traverse-2012-2017-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
