Oxygen (O2) Sensors

Oxygen sensors play a big part in keeping your engine running at peak performance. If you think your oxygen sensor is malfunctioning, there are a few factors to look into. One of the main symptoms of a faulty oxygen sensor symptom is a 15% decrease in mileage and that can really add up in your cost at the gas pump. An oxygen sensor can malfunction anywhere from 30,000 to 100,000 miles depending on type and vehicle.

The oxygen sensor in your vehicle acts as your engine's nose. The sensor sniffs out what's going on with your engine's exhaust and adjusts the incoming fuel-air mixture accordingly. If your oxygen sensor isn't working properly, your vehicle will not perform as well as it should. Replacing your vehicle's oxygen sensor at regular intervals keeps both your vehicle and the environment healthy by allowing your engine to run at peak efficiency, and avoids oxygen sensor problems.
