P0C59 Code - Drive Motor 'B' Position Sensor Circuit 'A' Intermittent/Erratic
Quick Answer
The motor resolver is a type of sensor that detects the position of the magnetic poles, which are indispensable for ensuring the highly efficient control of the MG1 and MG2. Common causes include Faulty Hybrid vehicle motor, Hybrid vehicle motor harness is open or shorted, Hybrid vehicle motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0C59 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 P0C59?
- Faulty Hybrid vehicle motor
- Hybrid vehicle motor harness is open or shorted
- Hybrid vehicle motor circuit poor electrical connection
- Faulty HV control ECU
