The factors influencing the cost of diagnosing and fixing the automobile fault code p0c66 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0C66 fault code refers to a problem with the Generator Position Sensor Circuit ‘A’ being low.

The resolver is a sensor used to detect the position of the magnetic poles in the rotor of a motor generator. The resolver contains a stator with an excitation coil and 2 detection coils (S, C).

An alternating current flows through the excitation coil, and the detection coils output currents based on the rotor position.

The MG ECU detects the absolute position of the rotor using the detection coils and their waveforms. The MG ECU also calculates the change in position over time to use the resolver as a speed sensor.

The P0C66 code indicates a malfunction in the signals output from the motor resolver.
