The automobile fault code P0C63 indicates a problem with the hybrid vehicle motor. The most common symptom is the engine light being ON or the service engine soon warning light.

The cause of this fault code can be 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.

It is important to address this issue promptly as it can affect the performance and efficiency of the vehicle. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for any broken, bent, pushed out, or corroded connector pins. The repair time for this issue is estimated to be around 1.0 hour.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and perform the necessary inspections and repairs accordingly.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0c63 fault code.

  • The symptoms of the automobile fault code p0c63 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The fault code p0c63 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.

  • The fault code P0C63 can be 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 the automobile fault code p0c63, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0c63, first, check the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0c63 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0C63 fault code refers to an intermittent or error in the drive motor ‘B’ position sensor circuit ‘B’.

This code indicates a problem with the sensor that detects the position of the magnetic poles in the motor resolver. The resolver is crucial for efficient control of the MG1 and MG2 in the vehicle. The resolver consists of a stator with an excitation coil and two detection coils. As the rotor turns, the gap between the stator and the rotor changes due to the rotor’s oval shape.

The detection coils S and C output alternating currents based on the rotor’s position. The HV control ECU uses the phases of these detection coils and the waveform height to determine the absolute position of the rotor. In addition to detecting the rotor’s position, the resolver can also be used as a speed sensor. The HV control ECU calculates the amount of change in the position within a specific time frame.

However, the P0C63 fault code indicates an intermittent or error in the drive motor ‘B’ position sensor circuit ‘B’, which requires further diagnosis and repair.

What are the possible causes of the automobile fault code p0c63?

If you see the engine light or service engine soon warning light on, the fault code P0C63 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, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to also check the possible causes listed above.

How can I visually inspect the wiring harness and connectors to fix the fault code p0c63?

If you’re dealing with the fault code p0c63 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 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. Look out for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0c63?

When troubleshooting the fault code P0C63, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. These issues can cause a poor electrical connection or an open/short circuit in the hybrid vehicle motor system. By thoroughly examining these areas, you can identify and resolve the underlying cause of the fault code.
