P0Ac1 Fault Code: Understanding The Description And Implications
The P0AC1 fault code refers to the Hybrid Battery Pack Current Sensor ‘A’ Circuit Low. This code is related to the battery current sensor, which is located on the positive cable side of the HV battery assembly.
The sensor detects the amperage that flows into the HV battery and sends a voltage signal to the battery smart unit.
When the output voltage of the battery current sensor is below 2.5 V, it indicates that the HV battery is being discharged. On the other hand, an output voltage above 2.5 V indicates that the HV battery is being charged. The power management control ECU uses this information to determine the charging and discharging amperage of the HV battery. In summary, the P0AC1 fault code indicates a low circuit in the Hybrid Battery Pack Current Sensor ‘A’.
This code helps diagnose issues with the HV battery’s charging and discharging amperage.
