The P1D86 automobile fault code can be caused by a faulty MPI module, open or shorted harness, poor electrical connection, or a faulty control module.

  • The automobile fault code P1D86 can be caused by a faulty Motor Power Inverter (MPI) Module.
  • It can also be caused by an open or shorted MPI Module harness.
  • Another cause can be a poor electrical connection in the MPI Module circuit.
  • Lastly, a faulty Motor Control Module can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1d86, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1d86, 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 P1D86 indicates an issue with the hybrid battery pack coolant pump control circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P1D86 fault code is related to the Motor Power Inverter (MPI) Module in an automobile. The motor control module receives an abnormality signal from the MPI module.

If the abnormality detection signal FOMOT is high and FOALL signal is low for a set time, the motor control module detects a malfunction and stores a DTC. The P1D86 code specifically indicates a malfunction in the Traction Motor Inverter Module Signal Line H.

What are the possible causes of the P1D86 automobile fault code?

If you’re experiencing the P1D86 fault code, your engine light may be on. This could be due to a faulty Motor Power Inverter (MPI) Module, an open or shorted MPI Module harness, a poor electrical connection in the MPI Module circuit, or a faulty Motor Control Module. To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
