P0C13 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0C13 can be explicated as Drive Motor "A" Inverter Phase W Over Temperature. The speed, direction and output torque of its respective drive motor generator is controlled by the motor control modules through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors. Every drive motor generator work utilizing 3 phase AC. The insulated gate bipolar transistor works a single phase of the drive motor generator. Each and every phase is specifically identified as U, V and W. The temperature of each phase is monitored by the motor control modules so that it can detect power inverter module over temperature conditions

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0C13 trouble code. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The drive motor "A" inverter phase W over temperature is being monitored by the engine control module. This trouble code would be set by the ECM when the drive motor "A" inverter phase W over temperature would not be as per the specifications set by the manufacturer.

What causes this problem with the Drive Motor "A" Inverter Phase W Over Temperature?

• The hybrid cooling system reservoir might have little coolant level
• Some issues related to the coolant pump

1. Generator Assembly - Are you aware of some warning signs of bad generator assembly? If no, then you have arrived at the right place. Its symptoms are dim lights, warning light, weak or sometimes dead battery, weird smell and odd sounds.
2. HVAC Blower Motor Control Module - A failure in the HVAC blower motor control module would lead to the major issues in the car heating and air conditioning systems.
3. Motor Assembly - Car engine might start running roughly or inconsistently due to faulty motor assembly. OBD Code P0C13 can appear because of faulty motor assembly.
4. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
5. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration. Buy high grade PCM online from us.
6. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues? It's better to replace it with a brand new one.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0C13 here:

Common Symptoms

• There can be an illuminated engine light
• Non operational high voltage system

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0C13:

• You must fix the defective engine control module
• It is essential to restore the flawed hybrid cooling system reservoir
• Rehabilitate the defaults in the coolant pump
• Carefully adjust the faults in the wirings

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

• Make sure that the battery cable connections are tight and clean. Some people think that it is an obvious step, but if your computer does not get a steady feed of electricity from the battery, it can cause multiple issues.
• Check for wires and connectors that might be rubbed through, disconnected or loose. It is also important to check the fuse box in your vehicle together with the relay centre that can be found under the hood.
• It is also important to make sure that the fuses are good. Make sure that there is no melted plastic that can cause fire.
• These are some of the major wiring problems that you will encounter with error code P0C13. Once you have completely checked all the obvious things and still you can’t find the right solution, then you have to begin suspecting either the computer or the sensor. 

Common Mistakes When Diagnosing The P0C13 Code

• Non performance of the drive motor generator power inverter control module
