The P025A code indicates an issue with your vehicle’s fuel pump. The fuel pump control module is part of a modern internal combustion engine’s returnless fuel system. It regulates the fuel pump to govern fuel pressure, which allows the vehicle to add fuel from the fuel tank to the engine. If you see this code, it means the Powertrain Control Module (PCM) or Engine Control Module (ECM) has recognized a problem with your vehicle’s fuel pump control module, which can result in serious issues surrounding the vehicle’s ability to utilize fuel effectively.
More About Error Code P025A
Code P025A doesn’t mean there’s a problem with the fuel pump or even that the fuel pump module is broken. This is a control circuit/open code, which means that there’s abnormal voltage coming from the fuel pump control module circuit. This could mean that all the pieces are working correctly, but there are issues with the circuit connections.

What Are the Symptoms of a P025A Code?
Depending on the severity of the P025A trouble code, your vehicle’s make and model, and the precise problem causing this code, you could experience various symptoms related to the P025A code. First, you should expect to see the check engine light illuminated. You may also see decreased engine performance, including engine stalls and general difficulty in starting the engine. The engine may also be difficult to start once you stop it.
What Are Some Causes of a P025A Code?
There are only two common causes of the P025A fault code. Usually, this code happens because of a defective fuel pump module, meaning you need to replace the fuel pump control module. In some cases, it could also be due to faulty fuel tank wiring within the fuel tank pump module and its connection to the PCM, including frayed wire problems, faulty connector pins, or problems with the power wires. In some very rare cases, it could be due to PCM failure, but you will usually see other warning signs if the problem is PCM failure.
How Serious Is the P025A Code?
The P025A code is extremely serious. Any time a code has to do with fuel pressure and administration, it’s a serious code. Your vehicle needs the right fuel delivery system to function properly. If you ignore this code, even if you don’t notice severe drivability symptoms, you may end up harming your vehicle in the long term with issues like fuel leaks and problems with the fuel rail pressure.
Can I Still Drive with a P025A Code?
You may physically be able to drive with the P025A active code, although more frequently, you’ll experience severe drivability concerns that will stop you from driving safely. Even if you can physically drive, avoiding doing so is best. It’s a very unpredictable code, and even if your fuel pressure isn’t impacted one minute, it may be impacted the next time you turn on your car, potentially leaving you stranded.
How Easy Is It to Diagnose a P025A Code?
Diagnosis for a P025A code can sometimes be fairly easy, but common mistakes occur regularly in the diagnosis process. Beginner DIYers frequently misidentify the problem, and they may replace the fuel pump module even if there’s no need to. If you’re an experienced DIYer, you may try to identify the problem, but if you don’t have significant experience, it’s best to take your problem to an expert.
How Difficult Is It to Inspect a P025A Code?
The inspection process for the P025A code can be more difficult than the diagnostic process. You might need special tools and protective equipment to inspect the P025A code. If you have issues with your vehicle’s fuel system, you need to know where the problem is coming from, whether there’s an issue with the wiring, or whether the fuel pump control module is malfunctioning. If you don’t have the tools necessary to determine this, you should leave it up to the experts.
