Description

An ACDelco GM Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle’s original component, and is a special feedback sensor on your vehicle’s exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized.
