If you see the engine light or service engine soon warning light illuminated on your dashboard, it could be due to the automobile fault code P16AD.

This code indicates a problem with the Glow Plug Control Module (GPCM). The cause could 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 for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this problem is estimated to be around 1.0 hour.

Make sure to check the “Possible Causes” listed above and take appropriate action.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p16ad fault code.

  • The symptoms of the automobile fault code p16ad include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p16ad 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 p16ad can be caused by the following: – Faulty Glow Plug Control Module (GPCM) – Open or shorted Glow Plug Control Module harness – Poor electrical connection in the Glow Plug Control Module circuit.

To fix the automobile fault code p16ad, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p16ad, follow these steps: 1.
  • Check the possible causes mentioned above.
  • 2.
  • Visually inspect the wiring harness and connectors related to the fault code.
  • 3.
  • Look for any damaged components.
  • 4.
  • Check for broken, bent, pushed out, or corroded pins in the connectors.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p16ad are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P16AD fault code indicates 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 DTC. The DTC is triggered when the voltage of one of the GPCM temperature sensors falls outside the calibrated threshold for more than 1.3 seconds.

This fault code specifically points to a low voltage issue in the GPCM temperature sensor circuit.

What are the possible causes of the automobile fault code p16ad?

If you see the engine light on or the service engine soon warning light, the fault code P16AD 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, be sure to look out for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the p16ad fault code?

If you’re dealing with the p16ad fault code and your engine light is on, it’s time to take action. The most common cause of this code is a faulty Glow Plug Control Module (GPCM), but it could also be due to an open or shorted harness or a poor electrical connection. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step could be the key to resolving the problem.

What should I look for when checking for damaged components and connector’s pins to resolve the p16ad fault code?

When resolving the p16ad fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing so, you can identify any issues with the Glow Plug Control Module (GPCM) or its circuit connections. This will help you determine if the fault lies with a faulty GPCM, an open or shorted harness, or a poor electrical connection.
