The P0C51 fault code refers to the Drive Motor ‘A’ Position Sensor Circuit ‘A’ RangePerformance. This code indicates an issue with the motor resolver, which is a sensor that detects the position of the magnetic poles in the MG1 and MG2 motors. The resolver consists of a stator with an excitation coil and two detection coils, and a rotor with an oval shape.

As the rotor turns, the gap between the stator and the rotor changes.

The detection coils S and C output alternating currents based on the position of the rotor. The HV control ECU uses the detection coils to determine the absolute position of the rotor and calculate the speed of the motor.

The P0C51 code suggests that there is a problem with the range or performance of the position sensor circuit for Drive Motor ‘A’. This issue should be addressed to ensure proper control and efficiency of the motor.

What are the possible causes for the automobile fault code P0C51?

If you see the engine light or service engine soon warning light on, the fault code P0C51 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 P0C51 fault code?

If you’re dealing with the P0C51 fault code and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This code can be caused by a faulty hybrid vehicle motor, an open or shorted motor harness, a poor electrical connection in the motor circuit, or a faulty HV control ECU. To fix it, check the possible causes mentioned earlier and give the wiring harness and connectors a thorough visual inspection.
