The automobile fault code P101C indicates a problem with the Glow Plug Control Module (GPCM). The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty GPCM, an open or shorted GPCM harness, or a poor electrical connection in the GPCM circuit. 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. The repair time for this issue is estimated to be around 1.0 hour. It is important to address this problem promptly to prevent further damage to the vehicle.

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the p101c fault code.

  • The symptoms of the automobile fault code p101c include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p101c can be caused by a faulty Glow Plug Control Module (GPCM), an open or shorted Glow Plug Control Module harness, or a poor electrical connection in the Glow Plug Control Module circuit.

  • The fault code P101C can be caused by the following: a faulty Glow Plug Control Module (GPCM), an open or shorted harness for the Glow Plug Control Module, and a poor electrical connection in the Glow Plug Control Module circuit.

To fix the automobile fault code p101c, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p101c, first, check the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p101c are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P101C fault code refers to a problem with the Glow Plug Control Module (GPCM) temperature sensor circuit. The GPCM is responsible for monitoring the voltage of the internal temperature sensor.

If the voltage is below 0.21 V or above 4.94 V, the GPCM will send a message to the Engine Control Module (ECM) to set the appropriate Diagnostic Trouble Code (DTC). The P101C code is triggered when the voltage of one of the GPCM temperature sensors remains outside the calibrated threshold for more than 1.3 seconds. This indicates a high voltage issue with the Glow Plug Control Module Temperature Sensor 2 Circuit.

What are the possible causes for the automobile fault code p101c?

If you see the engine light or service engine soon warning light on, the fault code P101C could be the culprit. This code is often caused by a faulty Glow Plug Control Module (GPCM), an open or shorted GPCM harness, or a poor electrical connection in the GPCM circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the p101c fault code?

To fix the p101c fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify any issues with the Glow Plug Control Module (GPCM) or if the harness is open or shorted. By checking these possible causes, you can take the necessary steps to resolve the issue and turn off the Engine Light or Service Engine Soon Warning Light.

What should I look for when checking for damaged components or corroded connector pins to resolve the p101c fault code?

When resolving the p101c fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By addressing these issues, you can effectively fix the problem and get rid of the Engine Light or Service Engine Soon Warning Light.
