A GM Genuine 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. This original equipment oxygen sensor has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
Features & Benefits:- Detect oxygen content in the exhaust gases to optimize emissions and fuel economy
- GM-recommended replacement part for your GM vehicle's original factory component
- Offering the quality, reliability, and durability of GM OE
- Manufactured to GM OE specification for fit, form, and function
 O2 Sensor Identification Guide An OBD Scan Tool will usually identify Oxygen Sensors by the Bank Number (B1 = Bank 1) and Sensor Number (S1 = Sensor 1). Bank 1 will always contain Cylinder 1, which is located closest to the front of the engine.
Part manufacturers often use different terms than scan tools to identify sensor positions. Regardless of the vehicle's engine orientation, the right or left bank is determined by viewing the engine from the rear (opposite the drive belts).
A Upstream Sensor (Before Converter)
B Downstream Sensor (After Converter)
C Left or Front Upstream Sensor (Before Converter)
D Right or Rear Upstream Sensor (Before Converter)
 Common O2 Sensor Contaminants Oxygen (O2) Sensors commonly fail due to contamination. When checking or replacing an O2 Sensor, visually inspect the sensor body to determine if it has been contaminated by a faulty part or substance upstream, and correct the fault before replacing the sensor.
