On the \u003cstrong\u003eVK56DE\u003c\/strong\u003e platform, aging sensors develop slow response rates and heater circuit failures, triggering fault codes like P0138, P0158, or P0420. Lagging voltage switching tricks the ECM into running rich trim corrections, which fouls spark plugs, over-fuels the cylinders, and accelerates premature catalytic converter failure under heavy towing loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 4-piece sensor pack replaces both upstream air-fuel ratio sensors and downstream heated oxygen sensors simultaneously to synchronize signal feedback across Bank 1 and Bank 2. Built with planar ceramic elements and fast-acting integrated heaters, these units reach operating temperature within seconds of cold-cranking. Double-laser-welded 304 stainless steel exterior shells prevent moisture contamination, while OE-spec harness lengths and factory-pinned weatherproof terminal blocks plug directly into the engine wiring harness without splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Upstream Oxygen Sensors (Bank 1 \u0026amp; Bank 2 Sensor 1)\u003c\/li\u003e\n  \u003cli\u003e2x Downstream Oxygen Sensors (Bank 1 \u0026amp; Bank 2 Sensor 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;\"\u003e2008-2012 Nissan Titan, 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\u003eVK56DE\u003c\/strong\u003e (5.6L V8) \/ \u003cstrong\u003eA60\u003c\/strong\u003e, \u003cstrong\u003eR51\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;\"\u003e310-317 hp \/ 385-388 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\u003e226A0-7S001\u003c\/strong\u003e, \u003cstrong\u003e234-9039\u003c\/strong\u003e, \u003cstrong\u003e250-54037\u003c\/strong\u003e, \u003cstrong\u003e250-54109\u003c\/strong\u003e, \u003cstrong\u003eES20172\u003c\/strong\u003e, \u003cstrong\u003eOS5393\u003c\/strong\u003e, \u003cstrong\u003eSG1692\u003c\/strong\u003e, \u003cstrong\u003e234-4835\u003c\/strong\u003e, \u003cstrong\u003e234-9038\u003c\/strong\u003e, \u003cstrong\u003e18213-82Z20\u003c\/strong\u003e, \u003cstrong\u003e22690-8U300\u003c\/strong\u003e, \u003cstrong\u003e22693-1AA0A\u003c\/strong\u003e, \u003cstrong\u003e22693-1AA0B\u003c\/strong\u003e, \u003cstrong\u003e22693-8W90A\u003c\/strong\u003e, \u003cstrong\u003e226A0-8U300\u003c\/strong\u003e, \u003cstrong\u003e226931AA0B\u003c\/strong\u003e, \u003cstrong\u003e226938W90A\u003c\/strong\u003e, \u003cstrong\u003e22693ET000\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\u003e2008-2012 Nissan Titan 5.6L V8 (Chassis: \u003cstrong\u003eA60\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Nissan Pathfinder 5.6L V8 (Chassis: \u003cstrong\u003eR51\u003c\/strong\u003e)\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 A60 Titan \u0026amp; R51 Pathfinder?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2012 Nissan Titan and Pathfinder equipped with the 5.6L \u003cstrong\u003eVK56DE\u003c\/strong\u003e engine; it does not fit 4.0L V6 Pathfinder models.\u003c\/p\u003e\n\n\u003ch4\u003eShould anti-seize compound be applied to the sensor threads prior to installation?\u003c\/h4\u003e\n\u003cp\u003eDirect-fit sensors typically come with anti-seize pre-applied, but if dry, apply a minimal amount of high-temp sensor-safe anti-seize exclusively to the threads, keeping the probe tip clean.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Endurance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle high-demand towing and severe off-road vibration, this sensor set maintains exact fuel trims across the \u003cstrong\u003eVK56DE\u003c\/strong\u003e platform to protect your exhaust catalysts and restore factory torque.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551478776056,"sku":"DS-EYYMLWFU6","price":89.95,"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-titan-pathfinder-2008-2012-5-6l-1.jpg?v=1790796978","url":"https:\/\/performancechiptuning.com\/fr\/products\/o2-oxygen-sensor-upstream-downstream-for-nissan-titan-pathfinder-2008-2012-5-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
