The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0A3F trouble code. The motor control module keeps an eye on the drive motor position sensor. It also monitors the angular position, speed and direction of the drive motor generator rotor based upon the signals of the resolver-type position sensor. There is a drive coil, two driven coils and an irregular shaped metallic rotor in the position sensor.

What causes this problem with the Drive Motor "A" Position Sensor Circuit?

• There can be inoperative drive motor generator
• There can be opened or shorted drive motor generator harness
• Drive motor generator circuit inferior electrical connection
