As switching frequency slows, the PCM receives delayed voltage feedback, forcing skewed short-term and long-term fuel trims. This thermal fatigue and silica poisoning trigger sluggish engine response, rich-running conditions, fouled spark plugs, reduced catalytic converter efficiency, and persistent check engine lights (P0130-P0161 series).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 4-piece complete bank replacement kit restores real-time AFR feedback for the \u003cstrong\u003e5.7L HEMI V8\u003c\/strong\u003e. Built with double-wall perforated stainless steel protection sleeves, these sensors shield the ceramic planar sensing core from thermal shock and particulate contamination. Pre-terminated factory-match yellow 4-pin inserts in durable black connector shells plug directly into the OEM wiring harness without splicing. High-temp silicone-sleeved wiring harnesses isolate sensitive mV signals from exhaust manifold heat radiant zones, ensuring rapid light-off times and accurate heater circuit continuity.\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;\"\u003e2012-2014 Dodge Durango\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;\"\u003e5.7L HEMI V8 \/ WD\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;\"\u003e360 hp \/ 390 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\u003e2012 Dodge Durango 5.7L V8 (Crew, R\/T, Citadel)\u003c\/li\u003e\n  \u003cli\u003e2013 Dodge Durango 5.7L V8 (Crew, R\/T, Citadel)\u003c\/li\u003e\n  \u003cli\u003e2014 Dodge Durango 5.7L V8 (Limited, R\/T, Citadel)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the WD Durango?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2012-2014 Dodge Durango equipped with the \u003cstrong\u003e5.7L HEMI V8\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to calibrate or tune the PCM after replacing these sensors?\u003c\/strong\u003e\u003cbr\u003e No calibration is necessary, but clearing active diagnostic trouble codes with an OBD-II scanner is required to reset adaptive fuel tables.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Powertrain Standard\u003c\/h3\u003e\n\u003cp\u003eMaintaining accurate lambda metering protects your catalytic converters from fuel washout while preserving the torque delivery and heavy-duty towing stability demanded of the \u003cstrong\u003e5.7L HEMI V8\u003c\/strong\u003e platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50511105392888,"sku":"DS-E4XBQTH0I","price":85.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/oxygen-sensors-for-dodge-durango-2012-2014-5-7l-upstream-downstream-1.jpg?v=1789410237","url":"https:\/\/performancechiptuning.com\/es\/products\/oxygen-sensors-for-dodge-durango-2012-2014-5-7l-upstream-downstream","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
