Slower sensor switching speeds alter the ECU's short-term fuel trim (STFT) feedback loop, causing rich-running conditions, unburned hydrocarbon buildup, rough idling, degraded fuel mileage, and trigger diagnostic trouble codes like P0130, P0135, P0420, or P0430.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis full replacement sensor kit provides matched factory impedance and rapid response times for both upstream air-fuel ratio sensing and downstream catalytic efficiency verification. Engineered with robust dual-protection tube housings, high-temperature ceramic sensing cores, and factory-pinned harness connectors, each direct-fit sensor resists soot fouling and moisture intrusion. Replacing all four sensors as a calibrated set ensures balanced cylinder bank telemetry across Bank 1 and Bank 2.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2pcs Upstream Oxygen Sensors\u003c\/li\u003e\n  \u003cli\u003e2pcs Downstream Oxygen Sensors\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;\"\u003e2004-2007 Nissan Murano\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\u003eZ50\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;\"\u003e245 hp \/ 246 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\u003e12499877\u003c\/strong\u003e, \u003cstrong\u003e18213-82Z20\u003c\/strong\u003e, \u003cstrong\u003e22690-8U300\u003c\/strong\u003e, \u003cstrong\u003e22693-7S000\u003c\/strong\u003e, \u003cstrong\u003e226936M400\u003c\/strong\u003e, \u003cstrong\u003e226937\u003c\/strong\u003e, \u003cstrong\u003e226937S000\u003c\/strong\u003e, \u003cstrong\u003e226A0-7S001\u003c\/strong\u003e, \u003cstrong\u003e234-5060\u003c\/strong\u003e, \u003cstrong\u003e2344297\u003c\/strong\u003e, \u003cstrong\u003e24244\u003c\/strong\u003e, \u003cstrong\u003eES20172\u003c\/strong\u003e, \u003cstrong\u003eOS5393\u003c\/strong\u003e, \u003cstrong\u003eSG1692\u003c\/strong\u003e, \u003cstrong\u003eADP83622800S\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\u003e2004 Nissan Murano 3.5L V6 (Base, SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2005 Nissan Murano 3.5L V6 (S, SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2006 Nissan Murano 3.5L V6 (S, SE, SL)\u003c\/li\u003e\n  \u003cli\u003e2007 Nissan Murano 3.5L V6 (S, SE, SL)\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 Z50 Murano?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2007 Nissan Murano equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo these sensors require wire splicing or repinning?\u003c\/h4\u003e\n\u003cp\u003eNo, each sensor features direct-fit OE-style harness plugs and pre-threaded bodies for plug-and-play installation without wire splicing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEnsure reliable fuel trims, clean throttle transitions, and long-term catalytic converter health under demanding city driving and highway cruising loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551287148792,"sku":"DS-E9ZLYH4Z5","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-murano-2004-2007-3-5l-1.jpg?v=1790794633","url":"https:\/\/performancechiptuning.com\/products\/o2-oxygen-sensor-upstream-downstream-for-nissan-murano-2004-2007-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
