The P0A45 fault code refers to a problem with the drive motor 2 position sensor circuit in an automobile. This sensor is monitored by the motor control module, which keeps track of the angular position, speed, and direction of the drive motor generator rotor. The position sensor consists of a drive coil, two driven coils, and a metallic rotor attached to the motor’s shaft.

When the vehicle is turned on, the motor control module sends a 7 volt AC, 10 kHz excitation signal to the drive coil, creating a magnetic field around the driven coils and the irregular-shaped rotor.

The module then monitors the two driven coil circuits for a return signal. The position of the metallic rotor causes the return signals of the driven coils to vary in size and shape. By comparing these signals, the motor control module can determine the precise position, speed, and direction of the drive motor generator rotor. It’s important to note that the position sensor is not a serviceable part of the drive motor generator.

If the P0A45 fault code is detected, it indicates an issue with the drive motor 2 position sensor circuit, which may require professional diagnosis and repair.
