Error Code P0C27: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0C27 can be described as Auxiliary Transmission Fluid Pump Motor Current Low. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

Error code P0C27 flashing? We have a wide range of automobile parts and accessories. We won’t let you down in any way as for us our customers are everything. Visit us as fast as you can. The motor control module is a part of the drive motor generator power inverter control module and the electric motor is controlled by it. The high voltage current driving the transmission is monitored by the motor control module. Now if the current is very less, then in that case the transmission would not be able to move the automobile. Whenever the motor control module would detect this, then the P0C27 fault code would start triggering.

What causes this problem with the Auxiliary Transmission Fluid Pump Motor Current Low?

• There can be distorted auxiliary transmission fluid pump control module
• Auxiliary transmission fluid pump control module harness is open or small
• Auxiliary transmission fluid pump control module circuit might have inadequate electrical connection

1. Electronic Control Unit - ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
2. Fluid Pump - The fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus, replace faulty pump now and buy a new one from us!
3. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
4. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
5. Fluid Pump Control Module - If the fluid pump control module has failed, it may result in transmission system failure and the fluid pump may not function properly causing performance issue. Replace faulty module components and reprogram the system immediately.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, so why not have a look?

Do you wish to diagnose P0C27 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• Now when the car is taken out for a test drive, if the P0C27 code does not return soon, he will know that there is an existence of erratic condition.

Common Mistakes When Diagnosing The P0C27 Code

• The auxiliary transmission pump might start failing
• Non observance of the transmission control module
• Some issues with the car wiring
