2015 Ford Transit Fuel Pump Control Module Location: Complete Guide to Finding and Replacing It

The bottom line: On the 2015 Ford Transit, the fuel pump control module (FPCM) is not located inside the fuel tank. Instead, it is mounted on top of the fuel tank, accessible from underneath the vehicle on the passenger side, near the rear of the van. This is a critical difference from the Ford Transit Connect, where the FPCM is integrated inside the tank. If you own a 2015 Ford Transit with a 3.5L or 3.7L engine, your vehicle may also be covered under Ford Customer Satisfaction Program 20B53, which offers a free replacement of the fuel pump control module.

The 2015 Ford Transit is a workhorse, but like many modern vehicles, it relies on electronic control modules to manage critical systems. One component that has caused headaches for many owners is the fuel pump control module (FPCM). This article will walk you through exactly where to find it, how to access it, common symptoms of failure, and what to do if yours needs replacement.

Understanding the Fuel Pump Control Module in the 2015 Ford Transit

The fuel pump control module is an electronic device that regulates the voltage supplied to the fuel pump. It receives signals from the engine control unit (ECU) and adjusts fuel pump speed based on engine demand. This system is designed to improve fuel economy, reduce emissions, and prevent fuel pump overheating. Without a functioning FPCM, the fuel pump may receive incorrect voltage, leading to insufficient or excessive fuel delivery.

Unlike older vehicles where the fuel pump simply ran at full speed whenever the engine was on, the 2015 Transit uses a variable-speed fuel pump controlled by this module. The FPCM modulates the voltage sent to the pump based on real-time engine needs, which helps optimize fuel delivery for efficiency and performance.

Exact Location of the Fuel Pump Control Module

The 2015 Ford Transit fuel pump control module is located on top of the fuel tank, at the very rear end of the tank, on the passenger side of the vehicle. This location is consistent across different engine configurations, including the 3.5L and 3.7L gasoline engines.

Here is what you need to know about accessing it:

1. Under-vehicle access required. The module is not accessible from inside the cabin or through a floor panel. You will need to get underneath the vehicle to reach it. The module sits above the fuel tank, which means you may need to partially lower the fuel tank to access it, although some owners report it can be reached by hand without fully removing the tank.

2. Look near the rear passenger side. If you crawl under the rear of the van, look on the passenger side (right side for US models). The module is a small black or gray box mounted directly on top of the fuel tank, near the back end of the tank.

3. Part numbers to know. The OEM part number for the fuel pump control module on the 2015 Ford Transit is F1FZ-9D370-A or F1FZ-9D370-B, depending on the specific build date and engine configuration. Some sources also list the part as GA8Z-9D370-A or AA8Z-9D370-A for certain configurations. The Ford parts catalog may refer to this component as a "control assy - fuel pump drive" or "fuel pump driver module."

4. Not to be confused with the fuel pump relay. The fuel pump control module is different from the fuel pump relay. The relay (part number 5M5Z-14N089-A) is located in the engine bay fuse box and simply switches power on and off. The FPCM actually regulates the voltage and controls pump speed.

Ford Customer Satisfaction Program 20B53: Free Replacement

If you own a 2015 Ford Transit with a 3.5L or 3.7L engine, there is important news: Ford issued Customer Satisfaction Program 20B53 in January 2021 to address premature failure of the fuel pump control module.

Key details about this program:

  • Affected vehicles: 2015 model year Ford Transit vehicles with 3.5L and 3.7L engines, built between February 3, 2014, and August 11, 2015 at the Kansas City assembly plant.
  • The problem: In some affected vehicles, the fuel pump control module that powers the fuel pump may fail prematurely. This would most likely occur at engine start, resulting in a malfunction indicator light illumination and an engine no-start symptom.
  • What Ford does: Dealers replace the fuel pump control module at no charge to the vehicle owner.
  • Program duration: The program was originally set to run through January 31, 2023, with no mileage limit. However, if you have not had yours replaced, it is still worth contacting a Ford dealer to check if your VIN is still eligible.

To check if your vehicle is covered, call any Ford dealer with your VIN handy. They can look up your vehicle in the OASIS system to see if it falls under this program.

Common Symptoms of a Failing Fuel Pump Control Module

Recognizing the symptoms of a failing FPCM can save you time and frustration. Here are the most common indicators:

1. Engine stalling. The engine may stall unexpectedly, especially under load or during acceleration. This happens because the engine is not getting enough fuel when demand increases. Some owners report stalling on highways, which is dangerous.

2. Difficulty starting. Hard starting or a no-start condition can occur. The fuel pump might not be receiving enough power to prime the fuel system. You may hear the starter cranking normally, but the engine will not fire up.

3. Check engine light with specific codes. The check engine light will often illuminate with diagnostic trouble codes (DTCs) related to fuel pump control. Common codes include:

  • P0230: Fuel Pump Primary Circuit Malfunction
  • P0627: Fuel Pump Control Circuit Open
  • P0628: Fuel Pump Control Circuit Low
  • P0629: Fuel Pump Control Circuit High

4. Reduced engine performance. You may notice a decrease in power and acceleration. The engine may feel sluggish or hesitant when you press the gas pedal.

5. Rough idling. The engine may idle roughly or erratically, sometimes surging or dropping rpm unexpectedly.

6. Poor fuel economy. A noticeable drop in fuel mileage can be a sign of improper fuel delivery caused by the FPCM not regulating voltage correctly.

Diagnostic Steps Before Replacing the Module

Before you spend money on a new fuel pump control module, you should perform some basic diagnostics to confirm it is truly the problem:

1. Scan for trouble codes. Use an OBD-II scanner to retrieve any stored DTCs. As mentioned above, codes P0230, P0627, P0628, and P0629 are directly related to the fuel pump control circuit. If you see these codes, the FPCM is a likely culprit.

2. Check for power and ground. Using a multimeter, verify that the FPCM is receiving power and has a good ground connection. Consult the vehicle's wiring diagram for specific pin locations. A faulty ground is a common culprit that can mimic FPCM failure.

3. Inspect wiring and connectors. Examine the wiring harness and connectors leading to the FPCM for corrosion, damage, or loose connections. The connector at the module is exposed to road grime and moisture, which can cause corrosion over time.

4. Listen for the fuel pump. When you turn the key to the ON position (without starting), you should hear the fuel pump prime for about 2-3 seconds. If you hear nothing, it could be a failed FPCM, a dead fuel pump, or a wiring issue.

5. Test fuel pressure. Use a fuel pressure gauge to verify that the fuel pump is delivering the correct pressure. Low pressure can indicate a failing FPCM or a problem with the fuel pump itself.

How to Access and Replace the Fuel Pump Control Module

If diagnostics point to a failed FPCM, here is the general procedure for replacement. Note that this is a challenging job, and if you are not comfortable working on fuel systems, it is best left to a professional.

What you will need:

  • Replacement fuel pump control module (OEM part F1FZ-9D370-A or B)
  • Basic hand tools
  • Safety glasses and gloves
  • Jack and jack stands
  • Fuel system depressurization tools (optional but recommended)

Step 1: Safety first. Working with the fuel system is hazardous. Always perform work in a well-ventilated area, wear eye protection, keep a fire extinguisher nearby, disconnect the battery, and follow Ford's service procedures for depressurizing the fuel system.

Step 2: Raise and secure the vehicle. Use a jack to raise the rear of the vehicle and place it securely on jack stands. You need enough clearance to work underneath the van.

Step 3: Locate the module. As described earlier, the FPCM is on top of the fuel tank at the rear, passenger side. You may need to remove some underbody shields or brackets to access it fully.

Step 4: Access the module. On some 2015 Transits, the module is accessible by hand without removing the fuel tank, but on others, you may need to partially lower the tank. If you need to lower the tank, support it with a transmission jack, remove the tank straps, and carefully lower it enough to reach the module on top.

Step 5: Disconnect the electrical connector. Unplug the wiring harness from the module. Inspect the connector for signs of corrosion or damage.

Step 6: Remove the module. The module is typically held in place by a bolt or bracket. Remove the fastener and pull the module free.

Step 7: Install the new module. Position the new FPCM in place, secure it with the bolt or bracket, and reconnect the electrical connector. Make sure the connector clicks firmly into place.

Step 8: Reassemble and test. If you lowered the fuel tank, raise it back into position and reinstall the tank straps. Reconnect the battery. Turn the key to ON (do not start) for 5 seconds, then OFF for 5 seconds. Repeat this three times to prime the fuel system. Then start the engine and check for proper operation.

Cost Considerations for Replacement

If you need to replace the fuel pump control module on your 2015 Ford Transit, here is what you can expect to pay:

DIY cost: The module itself typically costs between $60 and $150 for an OEM replacement, depending on where you buy it. Aftermarket options may be cheaper. Labor is free if you do it yourself.

Shop cost: If you have a mechanic do the job, expect to pay $300 to $600 total, including parts and labor. Labor time is typically 1.5 to 2.5 hours because of the awkward access location.

Ford dealer under warranty: If your vehicle is still covered under Customer Satisfaction Program 20B53, the replacement is free. This is your best option if your VIN qualifies.

Why the 2015 Ford Transit Is Different from the Transit Connect

It is important to note the difference between the Ford Transit and the Ford Transit Connect regarding the fuel pump control module. On the Transit Connect, the FPCM is integrated with the fuel pump inside the fuel tank, and access is through a floor panel in the cargo area. On the full-size Transit, the module is mounted externally on top of the tank, making it a separate, replaceable component.

This distinction matters because if you search online for information, you may find guides for the Transit Connect that do not apply to your full-size Transit. Always verify you are looking at information specific to the 2015 Ford Transit (full-size van), not the smaller Transit Connect.

Preventive Maintenance and Long-Term Reliability

To avoid future FPCM issues with your 2015 Ford Transit, consider these tips:

1. Keep the underbody clean. Road salt, mud, and moisture can accelerate corrosion on electrical components. Periodically cleaning the underbody, especially around the fuel tank area, can help extend the life of the FPCM and its connector.

2. Address check engine lights promptly. If you see a check engine light with any fuel system codes, do not ignore it. Early diagnosis can prevent a complete failure that leaves you stranded.

3. Use quality fuel. Contaminated fuel can cause problems throughout the fuel system, including placing extra strain on the FPCM. Use fuel from reputable stations and consider using a fuel system cleaner periodically.

4. Be aware of the 20B53 program. Even if you think your vehicle may not be affected, check with a Ford dealer. Some vehicles built outside the specified date range may still have similar issues, and Ford may offer goodwill assistance in some cases.

Final Thoughts

The 2015 Ford Transit fuel pump control module is located on top of the fuel tank, accessible from underneath the vehicle on the passenger side. If you experience stalling, hard starting, or check engine lights with fuel system codes, this module is a likely suspect. Before replacing it, check if your vehicle is covered under Ford's Customer Satisfaction Program 20B53, which provides a free replacement for affected vehicles.

Whether you tackle this repair yourself or take it to a shop, knowing exactly where the module is located and how to diagnose it will save you time and money. For many Transit owners, replacing a failed FPCM restores reliable operation and peace of mind on the road.
