Summary
- Diagnostic trouble code (DTC) P025A stands for “Fuel Pump Control Module Circuit/Open.”
- The P025A code is logged once the powertrain control module (PCM) detects abnormal voltages in the fuel pump control module’s circuit.
- Aside from a failed fuel pump control module, a P025A can also be caused by PCM issues and faulty wiring.

The fuel pump is responsible for transferring fuel from the fuel tank and into the engine at a certain pressure. Modern returnless fuel systems have a fuel pump control module that is responsible for regulating the fuel pump to govern fuel pressure. If you think your fuel pump has problems, you should connect a scan tool to see if the P025A code or similar codes have been triggered.
What Does the P025A Code Mean?
Diagnostic trouble code (DTC) P025A stands for “Fuel Pump Control Module Circuit/Open.” The P025A code is triggered when the powertrain control module (PCM) detects abnormal voltages in the fuel pump control module’s circuit.
Note: The definition of the P025A code might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P025A Code?
The P025A code is commonly caused by the following issues:
- Failed fuel pump control module
- PCM failure
- Faulty wiring
What are the Common Symptoms of the P025A Code?
You might experience the following symptoms if the P025A code is triggered:
- Illuminated check engine light
- Decreased engine performance
- Engine stalls
- Engine refuses to start
- Engine is difficult to start
How to Diagnose the P025A Code
Even though the code definition indicates a fuel pump control module issue, this might not always be the case. You need to properly diagnose the issue before you can do any fixes, or else you might end up replacing a functioning component.
If you’re not familiar with the process of diagnosing trouble codes, it might be best to have a trained mechanic do the job for you. However, you can also do it yourself if you’re confident in your DIY skills.
Want to learn how to diagnose the problem yourself? You can watch the video below to familiarize yourself with the process.
How to Fix the P025A Code
There are many ways to fix a specific OBD-II code because there are many possible causes. But without the right tools and technical knowledge, it can be hard to repair a P0216 code. This particular code might require you to inspect and test the fuel control module and PCM.
Since internal components can vary greatly among manufacturers, it might be best to bring your vehicle to the nearest repair shop and have a mechanic resolve the issue. But if you think you have the experience and automotive know-how to work on your vehicle, make sure to follow the right steps and observe the necessary protocols before you begin.
You should consult a repair manual or repair database when it comes to troubleshooting and repairing DTCs. Chilton repair manuals can also be useful. An ALLDATA DIY subscription might be better, as it provides detailed factory repair information for drivers who want to do the repairs themselves.
