Many Chevrolets, including the 2007-and-newer Silverado, Tahoe and Suburban, the Colorado, Equinox, Malibu, Impala and Cruze, don't run the fuel pump from a simple relay. A fuel pump control module (FPCM) receives the desired fuel pressure from the engine computer over the data network, reads a fuel pressure sensor and drives the pump with a pulsed signal to hold that pressure. When the FPCM detects a problem in its own circuits, the pump, or the pressure sensor, it stores a code and asks the engine computer to turn on the check engine light; P069E is the record of that request. The detailed code is inside the FPCM, and on the trucks the module sits under the vehicle on the frame near the spare tire, where road salt and water make connector corrosion a leading cause.
Can I keep driving? If the engine starts and pulls normally, drive gently and get it checked soon, because the pump may be running in a backup mode. If it stalls, hesitates badly or is hard to start, don't rely on it, especially in traffic, and never work near the fuel system with a spark source.
How to read P069E
- P Powertrain
- 0 Generic (SAE)
- 6 Computer & outputs
- 9E Specific fault
Symptoms
- Check engine light on
- Extended cranking or no-start, especially when warm
- Stalling or stumbling under load or when towing
- Engine runs but feels down on power at higher load
- Fuel pump running loudly or constantly
- U0109 or fuel pressure codes stored alongside
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Corroded or water-damaged FPCM connector or module, especially frame-mounted units on trucks
- Failed fuel pump motor drawing too much or too little current
- Internal FPCM failure
- Poor FPCM power feed or ground (fuse, frame ground, battery voltage)
- Fuel pressure sensor or its wiring faulty
- Damaged wiring between FPCM and pump at the tank
Diagnosis step by step
Read the FPCM's own codes
P069E only says the FPCM wants the light on. Use a GM-capable scan tool to open the fuel pump control module and read its codes, which point to the pump circuit, the pressure sensor or the module itself.
Tools: OBD-II scanner
Compare desired and actual fuel pressure
In live data, watch desired and actual fuel pressure plus pump duty cycle at idle and during a snap throttle or road test. Actual pressure should track desired within a few psi; a high duty cycle with low pressure points to a weak pump or restriction.
Tools: OBD-II scanner
Inspect the FPCM and connector
On trucks and SUVs, look at the module on the frame near the spare tire; on cars it's usually behind a trunk or rear trim panel. Unplug it and check for green corrosion, water inside the connector and swollen or burnt pins.
Tools: Flashlight, Screwdriver
Check power and ground under load
Back-probe the FPCM battery feed and ground while the pump runs. The feed should stay within about half a volt of battery voltage and the ground close to zero; a larger drop means a fuse, terminal or frame ground issue.
Tools: Multimeter
Verify with a mechanical gauge
Where there's a test port, connect a fuel pressure gauge to confirm the pressure sensor reading. If the gauge and the sensor disagree, the sensor or its wiring is the problem, not the pump.
Tools: Fuel pressure gauge, Gloves
Replace the faulty part and relearn
Replace the FPCM, pump or sensor depending on the stored code. A new FPCM may need programming with a GM-capable tool; clear codes and road test under load to confirm.
Tools: OBD-II scanner

Emissions / smog test impact
Will fail
P069E turns on the check engine light, so the vehicle fails a US OBD emissions test until the underlying FPCM fault is fixed and the monitors have completed.
Frequently asked questions
Is P069E a bad fuel pump?
Not necessarily. It only tells you the fuel pump control module has a stored fault. The FPCM's own code, and a comparison of desired and actual fuel pressure, decide whether it's the pump, the module, the sensor or wiring.
Where is the fuel pump control module on a Silverado or Tahoe?
On these trucks it's mounted underneath on the frame near the spare tire, exposed to water and salt. That's why corroded connectors and failed modules are common, and why an upgraded or sealed replacement is worth considering.
Why do I have U0109 with P069E?
U0109 means other modules lost communication with the FPCM. Together they suggest the module is dropping out, often due to power, ground or connector corrosion, rather than a pump problem.
Can I replace the FPCM myself?
It's usually a few bolts and a connector, so many owners do it. Depending on the vehicle, the new module may need to be programmed, so check whether you'll need a dealer or a shop with GM software afterward.
