Over time, the internal zirconium dioxide planar element suffers chemical poisoning and structural thermal fatigue. This leads to sluggish voltage switching times and false catalyst efficiency diagnostic trouble codes (DTCs such as P0420 or P0430). Furthermore, degraded internal ceramic heating elements frequently fail, delaying closed-loop readiness and throwing heater circuit faults that force the ECM into rich fuel trims, unnecessarily reducing fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM specifications, these 2-piece downstream heated oxygen sensors (HEGO) incorporate high-grade, fast-reacting ceramic thimble elements housed inside laser-welded, double-layered 304 stainless steel protective shells. This dual-shielded architecture shields the sensing core against particulate contamination and thermal shock. Pre-installed factory-grade harness wiring with heat-resistant sheathings and OE-correct pinouts ensure seamless signal integrity to the vehicle ECU, restoring factory switching speed, stabilizing secondary fuel trims, and resolving lingering downstream emission DTCs.\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;\"\u003e2007-2013 Nissan Altima 3.5L V6 Downstream (Bank 1 \u0026amp; Bank 2)\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\u003eVQ35DE\u003c\/strong\u003e \/ \u003cstrong\u003eL32\u003c\/strong\u003e, \u003cstrong\u003eD32\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;\"\u003e270 hp \/ 258 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\u003e226A0-JA10C\u003c\/strong\u003e, \u003cstrong\u003e226A1-JA10A\u003c\/strong\u003e, \u003cstrong\u003e226A0-JA10A\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2012 Nissan Altima Base, S, SE, SL, SR 3.5L V6 (Sedan - L32)\u003c\/li\u003e\n  \u003cli\u003e2008-2013 Nissan Altima SE, SR 3.5L V6 (Coupe - D32)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the L32 Altima?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2013 Nissan Altima equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e 3.5L V6 engine in both Bank 1 and Bank 2 downstream positions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill these sensors clear catalytic converter efficiency trouble codes like P0420\/P0430?\u003c\/strong\u003e\u003cbr\u003e If the code was triggered by a failing or slow-switching downstream sensor heater or element, these replacement units will restore proper signal response and allow the ECU to reset emission monitors.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Precision Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain the signature responsiveness of your \u003cstrong\u003eVQ35DE\u003c\/strong\u003e powertrain by eliminating faulty closed-loop sensor readings and ensuring optimal air-fuel calculation across the entire RPM range.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50511205335288,"sku":"DS-EIS8I3SOX","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/oxygen-sensors-for-nissan-altima-2007-2013-3-5l-downstream-1.jpg?v=1789411261","url":"https:\/\/performancechiptuning.com\/fr\/products\/oxygen-sensors-for-nissan-altima-2007-2013-3-5l-downstream","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
