The P1F01 fault code is related to the battery charger in hybridEV vehicles.

It indicates that the battery charger control module supply voltage sensor circuit is experiencing low voltage.

The battery charger measures internal voltages, currents, and temperatures to ensure proper performance. This fault code is triggered when the internal measurements verify that the charger is not performing properly due to low voltage in the sensor circuit.

The hybridEV powertrain control module 2 receives this information through serial data and is the host controller for Diagnostic Trouble Code (DTC) information.
