The automobile fault code P1FEC has an estimated repair time of 1.0 hour. The cost of fixing this code varies depending on the auto repair shop, with most charging between $75 and $150 per hour. These factors are influential in determining the overall cost of fixing the P1FEC fault code.

The P1FEC code is related to the hybrid battery in a vehicle. The battery contains 192 individual cells, which are electrically connected in series. The battery is divided into three sections, each containing a specific number of cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups. The battery energy control module contains internal interface control modules that monitor specific cell groups. The P1FEC code indicates a fault condition in the HybridEV Battery Interface Control Module 4 Voltage Sensor Performance.

The hybrid powertrain control module 2 receives diagnostic trouble code information from the battery energy control module.
