The Lambda sensor is located in your car’s exhaust system, upstream of the catalytic converter. Most modern vehicles also have a second Lambda sensor located downstream of the catalytic converter; this is designed to provide an extra layer of safety by analysing its performance.

As well as its importance in regulating the emission of harmful gasses into the environment, the Lambda sensor is key to the smooth running of your car’s catalytic converter. A faulty Lambda (or oxygen) sensor could seriously damage the catalytic converter, resulting in some very expensive repair work.

This essential piece of equipment therefore needs to be checked regularly and replaced if it is not working properly. Europarts.com stocks a range of top-quality sensors to fit every make and model of car.
