The factors influencing the cost of diagnosing and fixing the automobile fault code p125c are the estimated repair time of 1.0 hour and the typical auto repair shop charges of $75 to $150 per hour.
P125C Fault Code: Understanding The Description And Troubleshooting Tips
The P125C fault code is related to the Nitrogen Oxide (NOx) Sensor in your vehicle. The Engine Control Module (ECM) is responsible for monitoring this sensor. When the NOx Sensor does not meet the factory specifications, the ECM will set the P125C code in the On-Board Diagnostic II (OBDII) system.
The P125C code specifically indicates an issue with the heating supply voltage of the Nitrogen Oxide Sensor. This means that there may be a problem with the electrical supply that is responsible for heating the sensor.
It is important to address this issue promptly to ensure proper functioning of the NOx sensor and to maintain the overall performance of your vehicle.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P125C could be the culprit. This code is often caused by a faulty Nitrogen Oxide (NOx) sensor, an open or shorted NOx sensor harness, or a poor electrical connection in the NOx sensor circuit. To visually inspect these possible causes, check the wiring harness and connectors related to the NOx sensor. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.
