The factors influencing the cost of diagnosing and fixing the automobile fault code p0a65 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0A65 fault code refers to a high current in the ‘A’ phase W of the drive motor. The inverter in the vehicle converts the high-voltage direct current from the HV battery and the alternating current for the MG1MG2. It contains a three-phase bridge circuit with power transistors for MG1 and MG2 to convert the direct current and three-phase alternating current.

The HV control ECU controls the power transistors in the inverter. The motor inverter current sensors detect the amperage flowing through the cables between the inverter and MG1MG2.

The HV control ECU monitors these sensors for any malfunction in the sensor system.
