The P0C55 fault code refers to the Drive Motor ‘B’ Position Sensor Circuit ‘A’ in an automobile. This code indicates an issue with the sensor that detects the position of the magnetic poles in the motor resolver. The motor resolver is a crucial component for efficient control of the MG1 and MG2 in the vehicle.

It consists of a stator with an excitation coil and two detection coils. The rotor, which has an oval shape, rotates and changes the gap between the stator and the rotor. To determine the absolute position of the rotor, the HV control ECU analyzes the alternating currents generated by the detection coils S and C.

The CPU also calculates the speed of the rotor by measuring the amount of change in position over a specific time period.

If the P0C55 fault code appears, it means there is a problem with the Drive Motor ‘B’ Position Sensor Circuit ‘A’.

This issue should be addressed promptly to ensure proper functioning of the motor resolver and the overall control of the vehicle’s drive motor.

What are the possible causes for the automobile fault code p0c55?

If you see the engine light or service engine soon warning light on, the fault code P0C55 could be the culprit. This code is often caused by a faulty hybrid vehicle motor, an open or shorted hybrid vehicle motor harness, a poor electrical connection in the hybrid vehicle motor circuit, or a faulty HV control ECU. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the p0c55 fault code?

If you’re dealing with the p0c55 fault code and your engine light is on, it’s time to take action. The cause could be a faulty hybrid vehicle motor, an open or shorted harness, a poor electrical connection in the motor circuit, or a faulty HV control ECU. To fix it, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, like broken or bent pins, corrosion, or components that are out of place.
