P1A2F: The Low Pressure Fuel System Sensor Circuit – Explained

The P1A2F code is related to the hybrid battery voltage. It indicates that the voltage of the second battery is too high.

The Energy Storage Control Module (ESCM) uses battery voltage sensors to monitor the voltage of the batteries in the Energy Storage Box (ESB).

The ESCM monitors the voltage drop across the battery voltage sensors and uses the inputs for hybrid calculations.
