Product Details

Oxygen sensors, also known as Lambda probes, are an essential part of your vehicle's emissions system. They measure the amount of oxygen in your vehicle's exhaust, and relay this information back to your car's computer to adjust your fuel & ignition system accordingly. When they fail, they can cause poor fuel economy, reduced performance, and trigger a check engine light.
