The fault code P1E28 indicates an issue with the hybrid battery pack cooling system. 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 most shops 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 P1E28 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 a problem with the auxiliary transmission fluid pump control module and the hybridEV battery system voltage.

The drive motor control modules monitor their internal high voltage sensor for correct operation, and no external circuits are involved.

The motor control modules and the hybrid powertrain control module are part of the power inverter module and are not serviced separately.
