Aside from your vehicle’s main computer or powertrain control module (PCM), there are other modules in your vehThey can cause a number of drivability issues as well as a no-start condition if left unresolved.icle that control specific components and functions. These modules use input from various sensors and coordinate with each other to control a variety of outputs.
The P069E code indicates that the module responsible for keeping the fuel pump working has encountered a problem. What does this code mean and are there indications that you’re dealing with this fuel pump-related issue? This guide will answer these questions and more.
What Does the P069E Code Mean?
Diagnostic trouble code (DTC) P069E stands for “Fuel Pump Control Module (FPCM) Requested MIL Illumination.” It indicates that the FPCM has identified an issue in the fuel system and is requesting the PCM turn on the check engine light. Note that most older systems (and even some newer ones) don’t use a FPCM – these simply use a relay, and there are different codes for relay failures than for FPCM failures.

The FPCM supplies and regulates the voltage that goes to the fuel pump and the fuel pump relay. It can be a stand-alone module or a computer integrated into the PCM.
Usually, the FPCM is a stand alone module. Some fuel pump motors on late model vehicles are brushless three-phase DC motors that require a special module just for the pump to run. But fuel pump control modules tend to work under the command structure of the PCM to control fuel pressure being delivered from the in-tank pump in response to feedback from a pressure sensor. The more pressure that is required for the engine to do its work, the more current the FPCM is commanded to deliver to the pump. Typically, these modules don’t give much trouble.
Whenever the ignition is switched on and the PCM is activated, modules like the FPCM perform self-tests to ensure that they are working properly. The tests also allow the PCM to track the serial data that is transmitted over the data network.
The error code P069E is logged when the FPCM perceives problems with the fuel pump control system. The PCM illuminates the check engine light or the malfunction indicator lamp to indicate the issue.
What are the Possible Causes of the P069E Code?
There are several possible reasons why the FPCM might request the PCM to illuminate the check engine light. Most of them are connected to issues that concern the components and the circuitry of the fuel pump. Here are some of the possible causes of the P069E trouble code:
- Faulty fuel pump
- Faulty fuel pressure sensor
- Bad fuel pressure relay
- Wiring problems
- Problem with FPCM or PCM

What are the Common Symptoms of the P069E Code?
Your vehicle has ways of telling you that there’s something wrong with its parts other than illuminating the check engine light. As a DIYer, it’s best to familiarize yourself with the common symptoms of the error code P069E should you ever encounter it. They include the following:
- Check engine light is illuminated
- Hard start or no start condition, depending on the root cause of the issue
- Engine performance problems, such as delayed starting, power loss, drivability issues, and increased fuel consumption
- Engine idling speed fluctuates
- Other trouble codes
In some cases, there are no obvious symptoms save for a stored P069E code and an illuminated check engine light.
How to Diagnose the P069E Code
There are a handful of possible solutions to most OBD-II codes because they have several probable causes. The important thing about fixing an error code like the P069E is determining its exact root issue through rigorous troubleshooting.
Although it sounds intimidating, diagnosing and repairing OBD-II codes is possible with the help of resources like repair guides. Getting advice from your local mechanic is also helpful if you’re new to DIY repairs.
If you’re looking to expand your knowledge on the error code P069E, below are some helpful video resources that will give you an idea of what the troubleshooting process might involve:
How to Fix the P069E Code
As mentioned above, there are a lot of possible repair solutions for OBD-II codes. The P069E code is not an exception. Its repair depends not only on the root cause but also on the vehicle’s make and model.
Whether you’re a seasoned or a new DIYer, it’s important to get accurate repair information from credible sources. A repair guide or a subscription would be helpful if you plan on making repairs on your own. However, if you’re unsure about your skills in repairing the P069E code, you can go to your local mechanic to have the issue fixed.
Other Notes About P069E
Older fuel injection systems manage excess fuel pressure by returning fuel to the tank. Meanwhile, returnless systems typically use a stand-alone fuel control module to modulate the pump’s speed to control fuel pressure.
Returnless systems have an advantage over the older systems in terms of the reduction of evaporative emissions because the fuel is subject to less agitation and heating. The P069E code affects these electronic returnless fuel systems in that most of the root issues are more likely to affect emissions.
In any case, codes related to the fuel pump control module, like the engine code P069E, should always be addressed immediately. They can cause a number of drivability issues as well as a no-start condition if left unresolved.
