Guide To P025C OBD Error Code Solutions

<<See All OBD Codes

The fuel pump command (FPC) circuit is monitored by the powertrain control module. Now when the PCM would command the fuel pump ON, then the powertrain control module would be able to easily detect a short to the voltage on the FPC circuit. When the FPC would be commanded OFF by the powertrain control module, then the PCM would be able to detect an open circuit or a short to the ground on the FPC circuit. The test would fail due to less voltage or if it is greater than a calibrated limit.

The OBD-II code P025C can be defined as a Fuel Pump Module Control Circuit Low. It is the powertrain control module would supply voltage to the fuel pump control module. If there is some problem with the voltage supply to the fuel pump module, then P025C fault code would start appearing.

What causes this problem with the Fuel Pump Module Control Circuit Low?

• The fuel pump might be defective
• There can be some debris in the fuel pump screen
• Issues related to wiring
• The fuel pump command might have some faults
• Fuel pump command harness might be opened or shorted
• There can be some problems with the connector as it might be melted, disconnected and intermittent connections etc
• There can be poor electrical connection in the fuel pump command circuit
• Some defaults in the fuel pump module
• The engine control module might be malfunctioning

1. Fuel Pump - Do you remember when was the last time you got your car Fuel Pump checked up? A defective Fuel Pump can cause a lot of issues like displaying P025C code.
2. Fuel System - Poor Fuel System can cause a lot of difficulties, so why not get its parts replaced at time?
3. Engine Control Module - Are there some faults in your Engine Control Module? Don’t waste time and get them replaced or else P025C code can turn up.
4. Fuel Pressure Regulator - OBD Code P025C can appear because of faulty Fuel Pressure Regulator.
5. Powertrain Control Module - Everything is fine with Fuel Pressure Regulator and still P025C code triggering? Then you must get your Powertrain Control Module checked.
6. Air Fuel Ratio Sensor - There can be some issues with the Air Fuel Ratio Sensor due to which you may see P025C code appearing over and over again. Visit us to buy best quality Air Fuel Ratio Sensor online.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P025C code by mentioning some major symptoms below:

Common Symptoms

• Decrease in the engine performance
• Inaccurate amount of fuel level
• Fuel smell can start coming
• The engine light may start turning ON
• There can be some issues in starting the car engine
• Issue of hard start
• The car engine might start stalling
• The overall fuel mileage might be poor

Have a look at some ways with which you can correct the P025C code:

• The malfunctioning fuel pump should always be replaced
• The fuel pressure regulator should be repaired or replaced
• Make sure that you replace the air fuel ratio sensor
• You can always replace defective engine control module

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of fuel pump control module, oil pump, fuel pressure tester and many more. Now all your problems would vanish within no time.

You may require some things to diagnose and repair the fuel pump circuits and systems. They are mentioned here as follows:

• An OBD code reader
• A multimeter
• A socket set
• Basic ratchet and wrench sets
• Primary screwdriver set
• Battery terminal cleaner
• A service manual will also be required

You must follow some safety tips like:

• Allow your car engine cool down
• Check the wheels
• You must wear personal protective equipment

Note this point that you must verify and record the integrity of your battery as well as charging system before you start troubleshooting.

There can be a situation where you might find out that your car is not starting, then there is an extremely easy backyard diagnosing approach. If there is a fuel pump mounted inside the fuel tank of your vehicle, then you should give the tank a hit with a rubber mallet so that the debris is dislodged out of the pump while someone can try to start the vehicle. Now if your vehicle fries up when you are doing this, then your diagnosing is complete and there would be a need to replace the fuel pump. Keep this thing in mind that whenever diagnosing or repairing anything involves the fuel system, then you must make sure that there are no fuel leaks present. Using metal tools while working around the fuel is an avoidable hazard. So you must be cautious!
