Designed, tested, and validated by GM, it measures oxygen content in exhaust gases and provides the engine control module (ECM) with the feedback needed to maintain the ideal air\/fuel ratio for performance and fuel efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this heated O2 sensor affect engine performance?\u003c\/h3\u003e\n\u003cp\u003eThe sensor continually monitors exhaust oxygen levels and sends voltage signals to the ECM. With precise data, the ECM adjusts fuel injection and timing to approach the stoichiometric ratio, which helps maintain smooth running, efficient combustion, and stable idle behavior.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeated element reduces warm-up time for quicker, accurate readings\u003c\/li\u003e\n  \u003cli\u003eDirect-fit design matches factory connector and thread size\u003c\/li\u003e\n  \u003cli\u003eImproved combustion control when installed and calibrated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes a GM Genuine Parts O2 sensor different from aftermarket options?\u003c\/h3\u003e\n\u003cp\u003eGM Genuine Parts are produced to the same specifications as the parts installed at the factory or validated by GM, so fit, function, and durability mirror the original component.
