ACDelco GM Original Equipment Oxygen (O2) Sensors are special feedback sensors on your vehicle's exhaust system, and are GM-recommended replacements for your vehicle's original components. These sensors measure the proportion of oxygen in exhaust gases. Using this measurement, the engine control module (ECM) can adjust the air/fuel ratio to near the optimal value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. These original equipment oxygen sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
