Code P0C50 Description
The stator of the resolver contains an excitation coil and two detection coils. Because the rotor has an oval shape, the gap between the stator and the rotor changes as the rotor turns. An alternating current with a predetermined frequency flows through the excitation coil, and detection coils S and C output alternating currents in accordance with the position of the sensor rotor.
The HV control ECU detects the absolute position of the rotor in accordance with the phases of detection coils S and C and the height of their waveform. Furthermore, the CPU calculates the amount of change in the position within a predetermined length of time, in order to use the resolver as a speed sensor.
What are the Possible Causes of the DTC P0C50?
- Faulty Hybrid vehicle motor
- Hybrid vehicle motor harness is open or shorted
- Hybrid vehicle motor circuit poor electrical connection
- Faulty HV control ECU
