The fault code P1E9F 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 repair required. It is important to get this fault code diagnosed and fixed as soon as possible to avoid any further damage to the vehicle.

The P1E9F code refers to a fault in the HybridEV Battery Interface Control Module 3 5 V Reference Circuit. The drive motor battery contains 288 cells grouped into three sections. Each section is made up of a different number of cells and is individually serviceable.

The battery energy control module monitors the voltage of the 96 cell groups and communicates with the hybridEV powertrain control module 2 for diagnostic trouble code information.

The drive motor battery high-voltage interface control module encodes the voltage reading and transmits it to the battery energy control module through the battery control harness.

All components related to the battery energy control module and the drive motor battery high-voltage interface control module are serviceable.
