What is an Oxygen Sensor?

Oxygen Sensors (also known as Lambda Sensors) are located in the vehicle exhaust system. Their purpose is to measure the levels of unburned oxygen in the exhaust through changing voltages and to provide this information to the engines control computer. The engine's air/fuel mixture is then continually adjusted to ensure optimum engine performance and emission control.

Typical Symptoms of Failure

- Excessive fuel consumption
- High emissions, failing an MOT emissions test
- The Engine Management System records a Diagnostic Trouble Code ('Check Engine' Light may illuminate)
