oxygen sensor code

No car owner wants to see the inspection engine start. This warning sign is meant to tell you that your car needs maintenance or repairs. Usually, when the check engine light is on, it means your vehicle's exhaust system is not working properly. A key reason for the indicator light to turn on is the failure of the oxygen sensor. Learn more about this equipment to understand its importance and when to repair it.

The oxygen sensor in your car resides in your manifold and is employed to detect components of your exhaust (including oxygen!) that help your car monitor its performance. Your oxygen sensor’s readings are transmitted to your engine, in real-time, and helps your car determine its fuel-to-air ratio so as to maximize its performance.
