When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0c04 fault code.

  • The symptoms of the automobile fault code p0c04 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p0c04 can be caused by a faulty Hybrid Vehicle Motor Assembly, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code p0c04 can be caused by: a faulty Hybrid Vehicle Motor Assembly, an open or shorted Hybrid Vehicle Motor Assembly harness, and a poor electrical connection in the Hybrid Vehicle Motor Assembly circuit.

To fix the automobile fault code p0c04, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0c04, you need to 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 if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p0c04 are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p0c04 fault code.

The P0C04 fault code indicates that there is a high current in Drive Motor ‘B’.

This code is related to the three-phase windings of the stator coil in the motor. When three-phase alternating current flows through these windings, a rotating magnetic field is generated in MG2.

The system controls the rotation of this magnetic field based on the rotor’s position and speed. This control allows the permanent magnets in the rotor to generate torque.

The amount of torque generated is directly proportional to the current flowing through the windings.

The P0C04 code suggests that the current in Drive Motor ‘B’ is higher than normal, indicating a potential issue with the motor’s performance.

What are the possible causes for the automobile fault code p0c04?

If you see the engine light or service engine soon warning light on, the fault code P0C04 could be the culprit. This code is often caused by a faulty hybrid vehicle motor assembly, an open or shorted harness, or a poor electrical connection in the hybrid vehicle motor assembly circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the fault code p0c04?

If you’re dealing with the fault code p0c04 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 Assembly or an open or shorted harness. To fix it, check for any damaged components and look closely at the connectors for any broken, bent, pushed out, or corroded pins. Don’t forget to also check the other possible causes listed above.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0c04?

When resolving the fault code p0c04, start by checking for damaged components and connector’s pins. Visually inspect the related wiring harness and connectors, looking for any signs of damage such as broken, bent, pushed out, or corroded pins. This can help identify if the issue lies with a faulty Hybrid Vehicle Motor Assembly or if there is an open or shorted circuit. By thoroughly examining these areas, you can pinpoint the cause of the problem and proceed with the necessary fix.

p0c04 error fault code explained
