When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p101f fault code.

  • The symptoms of the automobile fault code p101f include the Engine Light being ON and the Service Engine Soon Warning Light being illuminated.

The automobile fault code p101f can be caused by a faulty Glow Plug Control Module, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code P101F can be caused by the following: a faulty Glow Plug Control Module, 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 p101f, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p101f, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p101f 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 P101F fault code indicates that the Glow Plug Control Module temperature sensor 1 is not plausible. This means that the temperature reading from sensor 1 is not within 12°C (54°F) of the readings from sensor 2 and sensor 3.

Additionally, if the difference between sensor 2 and sensor 3 is less than 12°C (54°F) for more than 2 seconds, the Diagnostic Trouble Code (DTC) will be set.

The Glow Plug Control Module will then send a message to the Engine Control Module (ECM) to trigger this fault code.

It is important to address this issue to ensure proper functioning of the glow plug system in your vehicle.
