Guide To P0C7A OBD Error Code Solutions

<<See All OBD Codes

What does the P0C7A error code signify? How does this error gets stored in the vehicle? If you are looking for a solution, then proceed further. The drive motor ‘B’ inverter voltage too high is usually referred to the high voltage system which does not function normally. The drive motor ‘B’ inverter is usually monitored by the engine control module. If the drive motor ‘B’ inverter is not up to the factory expectation, then the engine control module (ECM) will set the error code in the vehicle

The voltage that is sent to and from from the battery energy control module is looked after by the transmission control module. The P0C7A error code will get stored in the vehicle if the original voltage does not compete with the expected voltage.

What causes this problem with the Drive Motor "B" Inverter Voltage Too High?

• Damaged drive motor ‘B’ inverter.
• There might be an opening or the drive motor ‘B’ inverter harness might have a short circuit.
• The electrical connection of the drive motor ‘B’ inverter circuit might be weak.

1. Inverter - Inverters are used for a short time period so that a few of the devices can be powered which cannot be done efficiently with the help of a DC power. If you are looking for an inverter for your vehicle, get them from Parts Avatar.
2. Inverter Harness - The inverter installation kit usually comes with wire cables and fuse connectors so that the inverter can be properly connected in the vehicle. Any damage to this inverter harness must be fixed soon to avoid further troubles.
3. Engine Control Module - The engine control module is a type of electronic control unit which has the power to control a series of actuators on an internal combustion engine in order to make sure that the engine performs well. Any damage to the engine control module will result in a performance issue where it must be quickly replaced.
4. Powertrain Control Module - One main reason for a damaged powertrain control module is because of voltage overload where the voltage will be more than expected and it will likely damage the powertrain control module. The damaged powertrain control module will need immediate replacement so that the P0C7A error code can be avoided.
5. Engine Wiring Connectors - The engine wiring connectors are generally used to connect the terminals which run throughout the vehicle so that the supply of power to various electrical components is proper. Any damage to the engine wiring connectors will need replacement so that the vehicle functions normally.

It is vital 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 P0C7A here:

Common Symptoms

• Either the warning light of the service engine or the engine light will remain on.

Want to correct the Trouble Code P0C7A? Read these points mentioned below:

• Faulty drive motor ‘B’ inverter.
• The damaged engine wiring connectors need replacement.
• The defective drive motor ‘B’ harness and circuit has to be changed.
• Defective powertrain control module and engine control module needs fixation.

This code is related to P0C79.

Here are some steps which you should follow in order to diagnose this P0C7A fault code:

• This is a general type of error code but at times it is always best to leave it to the professionals as there are huge circuits involved.
• You will hear strange noises from the turning radiator fan and as well as the belt which rotates the fan blade.
• Even at times, there can be a presence of debris or clutch materials in the transmission pan which the mechanic will remove while inspecting them.
• You will find several other devices which are driven by the belt under the hood.
• All of these belts are driven by the engine pulley which is placed on the engine of an automobile.
• The serpentine belt is generally a belt which is available in every car so that it can drive multiple peripheral devices.
• The error code, P0C7A can also be activated by other trouble codes that are available down the lane.
• For instance, a murky MAF sensor might make your car to overreact in the adjustments of fuel trim.
• As an end result, you will likely find the oxygen sensor with some fuel mixture issues.
• Once every of the diagnosis is properly done, clear the codes and ask the mechanic to test drive the vehicle, to see if the error codes appear again.

Common Mistakes When Diagnosing the P0C7A Code

• Malfunctioning of the battery energy control module (BECM).
• There might be issues with wires.
