P025D - OBD Trouble Code

<<See All OBD Codes

The OBD-II code P025D can be defined as a Fuel Pump Control Circuit High.

It is the powertrain control module which would monitor the fuel pump module control circuit for a concern. When the powertrain control module would command the fuel pump as ON, then the powertrain control module would be able to detect a short to voltage on the fuel pump module circuit.

The powertrain control module would supply voltage to the fuel pump control module. If there are some issues in the process of voltage supply to the fuel pump module, then the P025D fault code would start appearing.

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.

What causes this problem with the Fuel Pump Control Circuit High?

• Defects in the fuel pump control module
• Harness of the fuel pump control module might be opened or shorted
• There can be poor electrical connection
• Some defaults in the fuel pump
• Wiring issues like frayed wire, melted, cut/open etc
• Defective engine control module

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 P025D 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 P025D code can turn up.
4. Fuel Pressure Regulator - OBD Code P025D can appear because of faulty Fuel Pressure Regulator.
5. Powertrain Control Module - Everything is fine with Fuel Pressure Regulator and still P025D 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 P025D code appearing over and over again. Visit us to buy best quality Air Fuel Ratio Sensor online.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The engine might not start
• There can be hard start
• The overall fuel mileage might be poor
• Inaccurate amount of fuel level
• Fuel smell can start coming
• Poor engine performance
• The car engine might start stalling
• Decrease in the engine performance
• The engine light may start turning ON

We have listed out some ways which would help you to correct the occurrence of OBD Code P025D. They are mentioned here as follows:

• The defective supercharger should be replaced
• If there are some issues in the spark plug, then it should be replaced
• The malfunctioning intake manifold actuator should always be replaced
• The fuel pressure regulator should be repaired or replaced
• Make sure that you replace the knock 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 cold air intake, Electric Supercharger, Air Pressure Gauge and many more. Now all your problems would vanish within no time.

If you want to diagnose and repair the fuel pump circuits and systems, then you will require the following things:

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

Here are some safety tips which should be followed:

• First of all, you must let the car engine cool down
• Check the wheels
• Wear personal protective equipment

If your car is not starting, then you should not worry as 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.

There can be a situation where 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.

You must 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. That’s the reason why you must be aware!
