By monitoring the oxygen proportion in exhaust gases, the sensor provides the feedback the engine control module (ECM) needs to correct fuel delivery and maintain the intended air\/fuel ratio. The result is a properly functioning emissions system, predictable driveability, and the durability expected from GM Genuine Parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this heated oxygen sensor affect my vehicle's fuel economy and emissions?\u003c\/h3\u003e\n\u003cp\u003eThe sensor supplies real-time oxygen readings that let the ECM adjust fuel injection for a near-stoichiometric air\/fuel ratio. When the ECM receives accurate data, it reduces wasted fuel and keeps emissions closer to designed levels without aftermarket guesswork.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeated element reduces warm-up time for accurate readings sooner after startup\u003c\/li\u003e\n  \u003cli\u003eDirect OE fit ensures proper positioning in the exhaust stream for reliable data\u003c\/li\u003e\n  \u003cli\u003eDurability and calibration match GM specifications to maintain long-term performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes this GM Genuine Parts sensor different from generic O2 sensors?\u003c\/h3\u003e\n\u003cp\u003eGM Genuine Parts are manufactured to the original equipment (OE) specifications used during vehicle production or validated by General Motors.
