  • To fix the automobile fault code p0a6b, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0a6b include the estimated repair time of 1.0 hour. Most auto repair shops typically charge between $75 and $150 per hour for their services.

These factors play a significant role in determining the overall cost of addressing the fault code.

The P0A6B fault code refers to a high current in the ‘B’ phase of the drive motor. The inverter in the vehicle converts the high-voltage direct current from the HV battery into alternating current for the MG1MG2 motors.

The inverter contains power transistors that control the flow of current. The HV control ECU monitors the inverter current sensors to detect any malfunctions in the sensor system. If the ‘B’ phase current is too high, it indicates a problem with the drive motor.

This fault code helps identify and diagnose issues related to the drive motor’s ‘B’ phase current.

What are the possible causes for the automobile fault code p0a6b?

If you see the engine light or service engine soon warning light on, the fault code P0A6B could be the culprit. This code is often caused by a faulty inverter with converter assembly, an open or shorted harness, or a poor electrical connection in the inverter with converter assembly circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage or corrosion, and check for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors related to the Inverter With Converter Assembly?
