P0C28 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0C28 can be elucidated as Auxiliary Transmission Fluid Pump Motor Current High. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

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.

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

• There can be inoperative auxiliary transmission fluid pump control module
• There can be opened or shorted auxiliary transmission fluid pump control module harness
• Auxiliary transmission fluid pump control module circuit inferior electrical connection

1. Engine Control Module - Most of the time it is difficult to intercept the ECM faults and thus must be checked for thoroughly. There can be a problem with the circuit or the software might have malfunctioned. Thus repair, replace or reprogram the component as per requirement.
2. Powertrain Control Module - If the PCM is faulty, it can store wrong OBD codes and can lead to misdiagnosis. This can happen due to misinterpretation of data received from the various sensors and components which also affects the vehicle’s performance. Thus, replace it immediately.
3. Transmission Fluid Pump - A failed transmission fluid pump can cause the fluid not being able to circulate in the transmission and the driver may smell the fuel burning. Thus, it might need immediate replacement.
4. Electronic Control Unit - If the ECU is at fault, it will not be able to read the boost converter temperatures correctly leading to underperformance. Thus, replace faulty ECU now!
5. Diagnostic Tool - Choose from our diagnostic tools collection that will come handy to detect and correct the OBD error code.
6. Transmission Fluid Pump Harness - The fluid pump harness can be faulty and cause transmission to underperform due to transmission slipping and harsh shift. Thus, check for harness faults and replace it now!

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.
• On test driving, if the P0C28 code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the transmission fluid as well as its level.
• If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.
• A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment.
• A noticeable pool of fluid underneath the car could be a sign of the cylinder head gasket failing. That can cause billowing smoke being blown from the exhaust system.
• A dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

Common Mistakes When Diagnosing The P0C28 Code

• There can be some faults in the drive motor generator power inverter control module
• Negligence in the auxiliary transmission pump
• Transmission control module problems
