Here are some symptoms to look out for:

  • The P1E20 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 vehicle.
  • Additionally, the code may indicate issues with the hybrid battery pack or the hybrid powertrain control module.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1E20 fault code in automobiles can be caused by various factors, including issues with the Program Power Inverter Module, faulty module, open or shorted harness, and poor electrical connection.

  • The automobile fault code P1E20 can be caused by several factors.
  • These include a faulty Program Power Inverter Module, a malfunctioning Power Inverter Module, an open or shorted Power Inverter Module harness, and a poor electrical connection in the Power Inverter Module circuit.
  • It is important to address these causes promptly to prevent further damage to the vehicle.

Below are some possible fixes for the automobile fault code p1e20, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1E20, 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 automobile fault code P1E20 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the P1E20 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P1E20 fault code is related to the power inverter module in hybrid and electric vehicles.

This module contains three motor control modules and the hybrid powertrain control module. The code indicates that the auxiliary transmission fluid pump control module is experiencing low voltage from the hybridEV battery voltage sense circuit. The drive motor control modules monitor their internal high voltage sensor for correct operation, and no external circuits are involved.

It’s important to note that the motor control modules and the hybrid powertrain control module are part of the power inverter module and are not serviced separately.

What are the possible causes of the P1E20 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1E20 fault code. This code is caused by a faulty power inverter module, poor electrical connection in the power inverter module circuit, or an open or shorted power inverter module harness. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
