The P1E29 fault code is related to the power inverter module in a hybrid vehicle. This module contains three motor control modules and the hybrid powertrain control module. The code specifically refers to an issue with the auxiliary transmission fluid pump motor control module’s calculated motor position performance.

The motor control modules and the hybrid powertrain control module share the power inverter module’s ignition voltage circuit, battery voltage circuits, and chassis earth.

The auxiliary transmission fluid pump motor control module uses sensorless control to estimate motor speed and position from the phase current sensors.

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 P1E29 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1E29 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.
