Oxygen Sensors

Your Oxygen (or O2) sensor is located in your vehicle’s emissions system and lets you know when they may be getting too high. If this sensor isn’t working properly, you may not get an accurate reading, or even worse – you may fail an emissions test. The sensor can become dirty and worn out, unable to send the correct signals. Usually, your check engine light will come on if there is an issue with the oxygen sensor.
