  • The automobile fault code P1EF6 can be caused by a faulty Hybrid Powertrain Control Module 2.
  • It can also be caused by an open or shorted Hybrid Powertrain Control Module 2 harness.
  • Additionally, a poor electrical connection in the Hybrid Powertrain Control Module 2 circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1ef6, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1EF6, 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 P1EF6 is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop.

The cost may also vary based on the severity of the issue and the type of vehicle.

It is important to get this fault code diagnosed and fixed as soon as possible to avoid any further damage to the vehicle.

The P1EF6 code is related to the Battery Charger Control Module. It indicates a problem with the Ignition OnStart Switch Circuit. The voltage in the circuit is too low, causing the ignition circuit to not energize properly.

This can occur when the vehicle power mode is in Vehicle ON or Vehicle in Service Mode. The BCM controls the ignition run relay through the control circuit by applying voltage to the circuit. The hybrid powertrain control module 2 sends the vehicle power mode status in a serial data message to various modules, including the battery charger control module.

What are the possible causes of the P1EF6 fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1EF6 fault code. This code is caused by a faulty Hybrid Powertrain Control Module 2, an open or shorted Hybrid Powertrain Control Module 2 harness, or a poor electrical connection in the Hybrid Powertrain Control Module 2 circuit. 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 I visually inspect the wiring harness and connectors related to the Hybrid Powertrain Control Module 2?
