Over continuous heat-load cycles, factory sensors suffer response lag and soot fouling, causing the ECM to miscalculate stoichiometric air-fuel targets. This results in erratic short-term fuel trims, decreased throttle response, excessive tailpipe emissions, and persistent P0130-P0161 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for exact OEM matching, this 4-piece sensor set features dual-layer laser-welded stainless steel shielding to defend against particulate contamination and thermal shock. Integrated ceramic planar heating elements minimize cold-start latency, forcing closed-loop operation within seconds. Factory-pinned terminal connectors and precision M18x1.5 threading ensure plug-and-play fitment into factory exhaust bungs, restoring precise voltage reporting across all four exhaust monitoring banks without wire splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 x Oxygen Sensors (Upstream and Downstream Positions)\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;\"\u003e2016-2019 Nissan Maxima\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\u003eA36\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;\"\u003e300 hp \/ 261 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\u003e22693-1PM0A\u003c\/strong\u003e, \u003cstrong\u003e226A0-BV81A\u003c\/strong\u003e, \u003cstrong\u003e234-4985\u003c\/strong\u003e, \u003cstrong\u003e234-4986\u003c\/strong\u003e, \u003cstrong\u003e234-9148\u003c\/strong\u003e, \u003cstrong\u003e22693-9HP0A\u003c\/strong\u003e, \u003cstrong\u003e226A0-4LA1A\u003c\/strong\u003e, \u003cstrong\u003e2344985\u003c\/strong\u003e, \u003cstrong\u003e2344986\u003c\/strong\u003e, \u003cstrong\u003e2349148\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\u003e2016-2019 Nissan Maxima (S, SV, SL, SR, Platinum) 3.5L 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 A36 Maxima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2016-2019 Nissan Maxima equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e 3.5L V6 engine. \u003cstrong\u003eDoes not fit 4-cylinder Nissan Altima or Rogue models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to clear ECM memory after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, clearing active diagnostic trouble codes and performing an ECM adaptive fuel trim reset using an OBD-II scan tool is required to synchronize closed-loop feedback immediately.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan VQ Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintain the aggressive throttle delivery and high-RPM power delivery of your VQ35DE with precise closed-loop fueling management that protects downstream catalytic converters and preserves factory horsepower.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551280922872,"sku":"DS-EDN3217US","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-nissan-maxima-2016-2019-3-5l-1.jpg?v=1790794485","url":"https:\/\/performancechiptuning.com\/products\/o2-oxygen-sensor-upstream-downstream-for-nissan-maxima-2016-2019-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
