Guide To P0C03 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0C03 can be defined as Drive Motor "B" Current Low. The thermistor resistance which is built into the motor temperature sensor would change as per the changes in the temperature of the MG2. Now if the temperature of the MG2 would be low, then the higher would be the resistance of the thermistor. Similarly, the increase in temperature would mean decrease in the resistance.

We learn more by looking for the answer to a question. That’s the reason why we are here to provide you the answers for all your questions. This error code would be set by the ECM when the drive motor "B" current circuit would not be as per the parameters set by the manufacturer.

What causes this problem with the Drive Motor "B" Current Low?

• Malfunctioning hybrid vehicle motor assembly
• Hybrid vehicle motor assembly harness might be open or little
• Substandard electrical connection in the hybrid vehicle motor assembly circuit

1. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? A dirty Powertrain Control Module can cause a lot of issues like displaying P0C03 code.
2. Motor Assembly - Poor Motor Assembly can cause a lot of difficulties, so why not get it replaced at time?
3. Engine Control Module - OBD Code P0C03 can appear because of faulty boost pressure/ turbocharger position sensor.
4. Motor Assembly Harness - Everything is fine with Engine Control Module and still P0C03 code triggering? Then you must get your Motor Assembly Harness checked.
5. Electronic Control Unit - A lot of issues can arise do to defective Electronic Control Unit. Did you just see P0C03 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
6. Body Control Module Component - Faulty Body Control Module Component can be the reason why P0C03 code is flashing. Visit us to purchase top notch Body Control Module Component online.
7. Hybrid Battery - It is an important auto part which needs full care. A faulty Hybrid Battery can be a reason behind the flashing up of P0C03 code.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes. The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur.

Visual inspection of the wiring and connectors to check for loose connections, corrosion, or shorts is done.

A specialized tool may be used to test the battery current sensor. Other tests of the hybrid battery and its components may help pinpoint the problem, as well as inspection of the wiring and connectors.

Disconnect and check the resistance and signal voltage from the battery current sensor. If all the components check out, inspect for the fault in the PCM as it can sometime store wrong OBD code and thus might need replacement or reprogramming.

Common Mistakes When Diagnosing The P0C03 Code

• Some issues related to the drive motor generator assembly
• Failure in the drive motor generator power inverter control module
