P0C5A Meaning

The motor resolver is a type of sensor that detects the position of magnetic poles, essential for ensuring highly efficient control of MG1 and MG2.
The resolver stator contains an excitation coil and two detection coils. Because the rotor has an oval shape, the gap between the stator and rotor changes as the rotor rotates. 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 HV control ECU detects the absolute position of the rotor based on the phases of the S and C detection coils and the height of their waveform. Additionally, the CPU calculates the amount of position change within a predetermined time period, in order to use the resolver as a speed sensor.

P0C5C Meaning

The drive motor position sensor is monitored by the motor control module. The motor control module monitors the angular position, speed, and direction of the drive motor generator rotor based on signals from the resolver-type position sensor. The position sensor contains a drive coil, two driven coils, and an irregularly shaped metal rotor. The metal rotor is mechanically attached to the drive motor-generator shaft. When the vehicle is turned on, the motor control module sends a 7V AC, 10 kHz excitation signal to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregularly shaped rotor. The motor control module then monitors the two driven coil circuits for a return signal. The position of the irregular metal rotor causes the magnetically induced return signals from the driven coils to vary in size and shape. Comparing the two signals from the driven coils allows the motor control module to determine the exact position, speed, and direction of the drive motor-generator rotor. The position sensor is a non-repairable part of the drive motor.

The drive motor position sensor is monitored by the powertrain control module. The powertrain control module monitors the angular position, speed, and direction of the drive motor generator rotor based on signals from the resolver-type position sensor. The position sensor contains one drive coil, two driven coils, and an irregularly shaped metal rotor. The metal rotor is mechanically attached to the drive motor-generator shaft. When the vehicle is turned on, the powertrain control module delivers a 7V AC, 10 kHz excitation signal to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregularly shaped rotor. The powertrain control module then monitors the two driven coil circuits for a return signal. The position of the irregular metal rotor causes the magnetically induced return signals from the driven coils to vary in size and shape. A comparison of the two signals from the driven coils allows the powertrain control module to determine the exact position, speed, and direction of the drive motor-generator rotor. The position sensor is a non-repairable part of the drive motor.
