The P1FE9 code is related to the hybrid battery in a vehicle. The battery contains 192 individual cells, which are electrically connected in series.

There are three distinct sections of the battery, each containing a different 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 P1FE9 code indicates a fault condition in the HybridEV Battery Interface Control Module 1 Voltage Sensor Performance.

The hybrid powertrain control module 2 is the host controller for diagnostic trouble code information.

What are the possible causes of the P1FE9 fault code in an automobile?

If you’re experiencing the P1FE9 fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated.
