Past 80,000 miles, internal ceramic heater elements deteriorate, causing sluggish switching frequency across stoichiometric thresholds. This degradation forces erratic short- and long-term fuel trim adjustments, triggering check engine warnings (DTCs P0130-P0161, P0420, P0430), degraded fuel economy, rough idle, and unburned hydrocarbon wash into the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis matched upstream air-fuel ratio and downstream oxygen sensor set restores factory closed-loop engine management. Constructed with dual laser-welded stainless steel protective shielding, high-grade ceramic sensing elements, and integrated rapid-heating coils, these sensors deliver instantaneous feedback to the ECM. Direct-fit weather-pack terminal connectors and OE-length high-temperature harness sleeves eliminate the need for wire cutting or splicing, maintaining factory resistance specs and signal fidelity equivalent to OEM parts \u003cstrong\u003e22693-1MR0A\u003c\/strong\u003e and \u003cstrong\u003e234-9135\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Upstream Oxygen Sensors (Air-Fuel Ratio Sensors)\u003c\/li\u003e\n  \u003cli\u003e2x 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;\"\u003e2011-2013 Infiniti G37, M37\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\u003eVQ37VHR\u003c\/strong\u003e \/ \u003cstrong\u003eV36\u003c\/strong\u003e, \u003cstrong\u003eCV36\u003c\/strong\u003e, \u003cstrong\u003eY51\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;\"\u003e330 hp \/ 270 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;\"\u003e19316342, 226931MR0A, 226933RC0A, 234-4380, 234-9135, 24781, 250-54102, 350-64083\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\u003e2011-2013 Infiniti G37 (Sedan, Coupe, Convertible) 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2011-2013 Infiniti M37 (Base, X) 3.7L 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 V36 \/ CV36 \/ Y51 G37, M37?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2013 Infiniti G37, M37 equipped with the \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e 3.7L engine. \u003cstrong\u003eConfirm your vehicle has the 3.7L V6; this set is not compatible with 2.5L, 3.5L Hybrid, or 5.6L V8 variants.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to reset ECU fuel trims after installing these sensors?\u003c\/h4\u003e\n\u003cp\u003eYes, clearing existing DTCs and performing an ECU reset or throttle relearn allows the ECM to clear stored fuel trim compensations and baseline new sensor signals immediately.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Calibration Standard\u003c\/h3\u003e\n\u003cp\u003eInfiniti's VVEL-equipped V6 engines rely heavily on fast-responding wideband data to maintain sharp throttle delivery and clean power.
