P0C67 Meaning

A resolver is a sensor used to detect the position of the magnetic poles of a motor-generator rotor. Knowledge of the pole positions is essential to ensure precise control of MG2 and MG1.

Each resolver contains a stator with an excitation coil and 2 detection coils (S, C). The gap between the stator and rotor changes as the rotor rotates because the rotor is oval-shaped. An alternating current with a predetermined frequency flows through the excitation coil, and the S and C detection coils produce alternating currents according to the position of the sensor rotor.

The inverter with converter (MG ECU) detects the absolute position of the rotor based on the phases of the S and C detection coils and the heights of their waveforms. Additionally, the CPU calculates the amount of position change over a predetermined time period to use the resolver as a speed sensor.

The MG ECU monitors the signals from the motor resolver and detects malfunctions.
