Error Code P0A7A: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0A7A can be explicated as Generator Inverter Performance. The high-voltage direct current of the HV battery is converted by the inverter as well as the alternating current for the MG1/MG2. There is a three-phase bridge circuit in the inverter which would consist of 6 power transistors each for the MG1 and the MG2. It would convert the direct current and the three-phase alternating current. The actuation of the power transistors is controlled by the HV control ECU.

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0A7A trouble code. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present.

Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Generator Inverter Performance?

• Malfunctioning inverter with converter assembly
• Inverter with converter assembly harness might be opened or shorted
• There can be inferior electrical connection in the inverter with converter assembly circuit
• High voltage control module might be flawed
