Failure Symptoms

The initial symptom of a failing sensor is often an illuminated check engine light accompanied by minor performance changes like a slightly rough idle. If ignored, the engine control unit may receive incorrect data, leading to poor fuel efficiency, increased emissions, and noticeable power loss. Continued operation with a faulty sensor can result in engine damage due to incorrect fuel/air mixture or overheating.

Installation Tip

Ensure the sensor port threads are clean and free of debris before installation to achieve a proper seal. Avoid using excessive force when tightening the sensor, as this can damage the threads or the sensor body.

Service Note

Check the engine wiring harness for any signs of damage or corrosion, and ensure the corresponding engine control module (ECM) is functioning correctly.
