The P0A63 fault code refers to a malfunction in the sensor system of the drive motor ‘A’ phase W Cu. The inverter in the vehicle converts the high-voltage direct current from the HV battery and the alternating current for the MG1MG2. The HV control ECU controls the power transistors in the inverter, which are responsible for converting the direct current and the three-phase alternating current.

The motor inverter current sensors detect the amperage that flows through the cables between the inverter and MG1MG2.

The HV control ECU monitors these sensors and detects any malfunction in the sensor system, triggering the P0A63 fault code. It is important to address this issue promptly to ensure proper functioning of the drive motor ‘A’ phase W Cu.
