This sensor latency causes improper short-term fuel trims, rough engine idle, decreased fuel economy, unmetered rich combustion cycles, and diagnostic trouble codes such as P0131, P0133, or P0134 that compromise emissions compliance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement upstream sensor utilizes an advanced planar ceramic zirconia core paired with porous platinum electrodes to deliver microsecond-level stoichiometric feedback to the ECM. Encased in a 430 stainless steel body with a dual-layer exterior shield, it repels soot buildup while insulating the internal element from thermal shock and road debris. An integrated internal ceramic heater circuit accelerates light-off to reach optimal operating temperature rapidly, restoring crisp closed-loop fueling, stable manifold vacuum, and smooth throttle response without circuit wiring modifications.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e2010-2014 Chevrolet Equinox\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;\"\u003e2.4L Ecotec (LAF \/ LEA) \/ GM Theta\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;\"\u003e182 hp \/ 172 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010-2014 Chevrolet Equinox LS, LT, LTZ (2.4L I4)\u003c\/li\u003e\n  \u003cli\u003e2010-2014 GMC Terrain SLE, SLT (2.4L I4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GM Theta Equinox?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2010-2014 Chevrolet Equinox equipped with the 2.4L \u003cstrong\u003eEcotec LAF\u003c\/strong\u003e or \u003cstrong\u003eEcotec LEA\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve an active P0135 heater circuit DTC?\u003c\/strong\u003e\u003cbr\u003e Yes, the integrated internal ceramic heating element restores specified circuit resistance to resolve heater-related diagnostic fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained thermal exhaust loads and daily commuter duty cycles, this upstream O2 sensor provides reliable feedback to protect your catalytic converter and preserve fuel efficiency across all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50511163883768,"sku":"DS-ENZ5EQTZ3","price":69.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/oxygen-sensors-for-chevrolet-equinox-2010-2014-2-4l-upstream-1.jpg?v=1789410942","url":"https:\/\/performancechiptuning.com\/es\/products\/oxygen-sensors-for-chevrolet-equinox-2010-2014-2-4l-upstream","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
