The P1E21 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 there is an issue with the auxiliary transmission fluid pump control module’s hybridEV battery voltage sense circuit, specifically with high voltage.

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.
