The P1D5C automobile fault code indicates an issue with the sensor ground circuit in the transmission control module (TCM). The most common symptom is the engine light turning on. The cause could be an open or high resistance in the sensor ground circuit or a short circuit to voltage.

The repair is of moderate difficulty and importance, requiring a visual inspection of the wiring harness and connectors for any damage or corrosion. The fault code can be interpreted using an OBD-II scanner.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON, it could be a sign of p1d5c fault code.

Here are the symptoms to look out for:

  • The P1D5C fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting issues, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1D5C fault code in automobiles can be caused by a range of issues, including sensor ground circuit problems and a faulty TCM.

  • The automobile fault code P1D5C can be caused by a Sensor Ground Circuit Open or High Resistance.
  • It can also be caused by a Sensor Ground Circuit Shorted to voltage.
  • Another possible cause is a Faulty Transmission Control Module (TCM).

To fix the p1d5c automobile fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1d5c, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code is P1D5C. The estimated repair time is 1.0 hour. The cost of fixing the fault code depends on the repair time.

Most auto repair shops charge between $75 and $150 per hour. Therefore, the fixing cost can range from $75 to $150.

P1D5C is a fault code that checks for a loss of connection of the sensor ground reference. The common ground reference is provided to all sensors by the Transmission Control Module (TCM) via three different connector pins. The most critical sensors have their ground reference connected to both GNDSENS1 and GNDSENS2 to ensure that the system continues to work properly even if one of the ground pins is disconnected.

When a loss of connection of both GNDSENS1 and GNDSENS2 or only GNDSENS3 is detected, the diagnostic will set a fault in the TCM.

What are the possible causes of the P1D5C fault code when the engine light is on?

If your engine light is on and you’re getting the P1D5C fault code, it could be due to a sensor ground circuit that’s either open, has high resistance, or is shorted to voltage. Another possible cause could be a faulty Transmission Control Module (TCM). To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P1D5C fault code?

If you’re experiencing the P1D5C fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. First, check the Possible Causes listed above, which include a Sensor Ground Circuit Open or High Resistance, a Sensor Ground Circuit Shorted to voltage, or a Faulty Transmission Control Module (TCM). To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

Is a faulty Transmission Control Module (TCM) a common cause of the P1D5C fault code?

The P1D5C fault code can be caused by a faulty Transmission Control Module (TCM), as well as an open or high resistance sensor ground circuit or a shorted sensor ground circuit to voltage. If the engine light is on, it is recommended to visually inspect the related wiring harness and connectors for any damage or corrosion. Checking for broken, bent, pushed out, or corroded connector’s pins is also advised.
