The fault code P1E7A is a diagnostic trouble code related to the hybrid battery pack. The code indicates that there is an issue with the battery pack’s cooling system.

The estimated repair time for this issue 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. Therefore, the total cost of fixing this issue can range from $75 to $150.

The P1E7A code refers to a fault in the HybridElectric Vehicle Battery 79 Circuit.

The battery pack contains 288 cells grouped in parallel and series.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules.

The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2.

The hybridEV powertrain control module 2 is responsible for diagnostic trouble code information.
