P025D Fault Code

P025D OBD-II Trouble Code Short Description

Fuel Pump Module Control High

What does trouble code P025D mean?

The P025D fault code is an OBD-II generic code indicating a problem with the fuel pump module control circuit. It means that the fuel system has detected a high voltage signal coming from the fuel pump module control circuit.

This fault code is usually caused by a faulty fuel pump control module or a damaged wiring harness connected to the fuel pump module. Other possible causes include a faulty fuel pump relay, a blown fuse, or a malfunctioning PCM.

To fix this problem, you will need to diagnose the root cause of the code and then replace any faulty components as necessary. In some cases, a simple reset of the system may be all that is needed to clear the code and restore normal operation.

Overall, the P025D fault code is a serious issue that should be addressed promptly to prevent further damage to your vehicle's fuel system and avoid potential safety hazards. Therefore, it is recommended to take your car to a mechanic or certified technician who can diagnose and fix the issue properly.


What are the symptoms of the P025D code?

Symptoms of a P025D error code may include:

  • Check Engine Light (CEL) illuminated on the dashboard
  • Reduced engine power or performance
  • Difficulty starting the engine
  • Engine stalling or cutting out during operation
  • Fuel economy decreased
  • Gas smell from the exhaust
  • Fuel leakage detected

It is important to address this error code promptly as it can lead to poor engine performance and even safety hazards. A thorough diagnosis by a certified mechanic is recommended to determine the underlying issue and prevent further damage to the vehicle.


What causes the P025D code?

P025D is a generic OBD-II code that indicates a malfunction in the fuel pump module control circuit. The possible causes of this code include:

  1. Faulty fuel pump module
  2. Open or short circuit in the fuel pump module control wiring
  3. Defective fuel pump relay
  4. Malfunctioning fuel pressure sensor
  5. Corrosion or damage in the fuel pump module connectors or terminals

To diagnose and fix this issue, it is recommended to have the vehicle inspected by a certified mechanic. They will perform a series of tests and checks to pinpoint the exact cause of the fault and carry out the necessary repairs or replacements.

Possible Solutions

How to fix P025D?

There are several potential causes for the P025D fault code, including:

  1. A problem with the fuel pump module control circuitry, such as damaged wiring or a faulty control module.

  2. A problem with the fuel pump itself, such as a clogged filter or a failing motor.

  3. A problem with the fuel pressure sensor, which may be malfunctioning or sending inaccurate readings to the engine management system.

  4. A problem with the fuel system computer, which may be failing to properly interpret data from the fuel pump module.

To fix the P025D fault code, you should start by performing a visual inspection of the fuel pump module and associated wiring to check for any obvious signs of damage or wear. You may also want to perform a fuel system pressure test to check for more serious issues with the fuel pump or fuel pressure sensor.

If you're not comfortable performing these tasks yourself, it's always best to take your car to a certified professional for diagnosis and repair. They will have the experience and specialized tools needed to identify and fix the underlying issue causing the P025D fault code.
