Jeep O2 Sensors | Quadratec

An oxygen sensor monitors exhaust gasses so the ecu can keep your Jeep's engine running at peak performance and optimal cyondition. If the O2 sensor in our Jeep is bad, you could potentially be wasting fuel and getting poor gas mileage.

In fact, an early sign that your O2 sensor is failing is decreased gas mileage. If a sensor is starting to go bad, you may even notice it before a check engine light warns you of a problem.
