Lambda Sensors

Your car's Lambda sensor is basically just an oxygen sensor, analysing and detecting the level of oxygen in your car's engine and exhaust system, helping to minimise the poisonous gases released into the environment by your car's exhaust.

It feeds information back to the car's ECU, telling it how much air and fuel it needs in the combustion mix in order to lower the emissions while keeping optimal performance.

Replacing the Lambda sensor isn't usually too expensive or difficult, but if it's not done it can cause problems with the catalytic converter or other parts of the car, which will then be far more expensive and difficult to fix.

Put simply, it's best to change the Lambda sensor if you're in any doubt as it'll be a lot cheaper and easier in the long run. If you need a hand, just ask a member of our team in-store.
