  • The symptoms of the automobile fault code p0a6a include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The fault code p0a6a can be caused by a faulty inverter with converter assembly, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code p0a6a can be caused by: a faulty Inverter With Converter Assembly, an open or shorted Inverter With Converter Assembly harness, and a poor electrical connection in the Inverter With Converter Assembly circuit.

To fix the p0a6a fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0a6a, 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 p0a6a based on the estimated repair time of 1.0 hour include the following: – The repair time of 1.0 hour is a significant factor in determining the cost. – Auto repair shops typically charge between $75 and $150 per hour for their services. – The hourly rate charged by the repair shop will directly impact the overall cost of diagnosing and fixing the fault code. – Other factors such as the complexity of the repair, the availability of parts, and any additional labor or materials required may also affect the final cost.

The P0A6A fault code refers to a specific issue with the drive motor ‘B’ phase V current being too low. The inverter in the vehicle is responsible for converting the high-voltage direct current from the HV battery into alternating current for the MG1MG2 motors.

The inverter contains power transistors for both MG1 and MG2, which help convert the current.

The HV control ECU is in charge of controlling the power transistors in the inverter.

The inverter also sends important information, such as amperage and voltage, to the HV control ECU for proper control. The motor inverter current sensors detect the amperage flowing between the inverter and MG1MG2.

If the HV control ECU detects a malfunction in the sensor system, it triggers the P0A6A fault code. This fault code specifically indicates that the drive motor ‘B’ phase V current is lower than expected.

Addressing this issue may require further diagnosis and repair by a qualified technician.

What are the possible causes for the automobile fault code p0a6a?

If you see the engine light or service engine soon warning light on, the fault code P0A6A 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.
