NOx Sensor, Front (3.0lt TD) | A0009053503

NOx sensors monitor the level of nitrogen oxide emitted by a diesel vehicle to ensure compliance with emissions regulations. Most engines feature two NOx sensors: an upstream and downstream sensor. Common causes of failure include soot buildup on the sensor, ECU water intrusion and/or damage to the cable, which will cause the check engine light to illuminate.
