Over time, silica contamination, oil blow-by, and continuous thermal stress poison the internal zirconia ceramic sensing elements. This degradation leads to sluggish switching response, false lean readings, unmetered rich fuel trimming, poor fuel economy, rough idle, and persistent DTCs like P0130, P0138, P0420, or P2A00. Replacing isolated sensors often leaves mismatched impedance across engine banks, resulting in erratic ECU air-fuel management.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 4-piece upstream and downstream sensor kit restores factory-calibrated closed-loop air\/fuel ratio feedback for both Bank 1 and Bank 2. Built with precision-engineered planar zirconia ceramic thimbles and integrated platinum electrodes, each sensor provides millivolt-level signal fidelity and ultra-fast light-off response via dual-layer protective heater circuitry. High-temperature fluoropolymer-insulated wiring harnesses, double-sealed stainless steel protective bodies, and direct-fit OEM pin-matched connectors ensure long-term resistance against exhaust vibration, thermal degradation, and moisture intrusion.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 x Direct-Fit Oxygen Sensors (Upstream and Downstream Set for Bank 1 \u0026amp; Bank 2)\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;\"\u003e2015-2019 Nissan Murano, Pathfinder\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\u003e3.5L V6 (VQ35DE \/ VQ35DD)\u003c\/strong\u003e \/ \u003cstrong\u003eZ52 (Murano), R52 (Pathfinder)\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;\"\u003e260-284 hp \/ 240-259 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\u003e2015-2019 Nissan Murano 3.5L V6 (S, SV, SL, Platinum)\u003c\/li\u003e\n  \u003cli\u003e2015-2019 Nissan Pathfinder 3.5L V6 (S, SV, SL, Platinum)\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 Z52 and R52 Murano and Pathfinder?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2019 Nissan Murano and Pathfinder equipped with the \u003cstrong\u003e3.5L V6\u003c\/strong\u003e engine.
