Most auto repair shops typically charge between $75 and $150 per hour for their services.

The P1392 fault code is stored in the Engine Control Module (ECM) when there is an issue with the output from the Camshaft Position Sensor. This can be due to the sensor not providing the expected signal or the signal being completely missing.

To validate the signal, the ECM relies on information from the Crankshaft Position Sensor. It is important to inspect the phonic wheel for the camshaft position, as incorrect fitment or damage can affect the signal.

Additionally, incorrect valve timing or issues with the variable valve timing system can also cause this fault.

It is crucial to test the operation of the variable valve timing system and ensure a good quality oil supply for its correct functioning. Lastly, when this fault occurs, it is recommended to inspect the lubrication system as well.

What are the possible causes for the automobile fault code p1392 and how can I visually inspect them?

If you’re seeing the fault code P1392 and your engine light is on, it could be due to a faulty Camshaft Position (CMP) Sensor, an open or shorted Camshaft Position Sensor harness, a poor electrical connection in the Camshaft Position Sensor circuit, or a faulty Engine Control Module (ECM). To visually inspect these possible causes, check the wiring harness and connectors related to the sensor. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.

How does a faulty Camshaft Position Sensor (CMP) contribute to the engine light being ON and what steps can I take to fix it?

If you notice the engine light or service engine soon warning light is on, it could be due to a faulty Camshaft Position Sensor (CMP). This can happen if the sensor itself is faulty, if the sensor harness is open or shorted, if there is a poor electrical connection in the sensor circuit, or if the Engine Control Module (ECM) is faulty. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

What should I do if I suspect that the Engine Control Module (ECM) is faulty and causing the p1392 fault code?

If you suspect that the Engine Control Module (ECM) is causing the p1392 fault code, there are a few steps you can take. First, check for the symptom of the engine light being on or the service engine soon warning light. Then, consider the possible causes, which include a faulty camshaft position sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a faulty ECM. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look for any broken, bent, pushed out, or corroded pins in the connectors.
