What P069E means
P069E is not a component fault but a notice in the engine module: the separate fuel pump control module has detected and stored an emission-related fault of its own and requests the check engine light – over serial data or, on older systems, a request line.
How the engine computer detects it
GM uses it (2014–2019 tables) and lists P069E itself as 'type A, no MIL': the lamp is lit because of the fault in the pump module, not because of P069E. The actual cause must therefore be read from the fuel pump module's own memory – typically pump circuit, fuel pressure sensor, module overheating or supply. On GM diesels (2014) this module also controls the active grille shutters. Clear the code only after repairing the module's fault.
Written from public technical sources and not yet checked by a mechanic. How we write these pages
Symptoms
- Check engine light on
- Possibly hard start, stumbling or lack of power from fuel supply problems
- Further codes stored in the fuel pump module
Common causes
- Fault in the fuel pump circuit (pump, wiring, ground) stored in the pump module Most likely
- Fuel pressure sensor or its wiring or 5 V reference Possible
- Pump module faulty internally or overheated (corrosion, moisture) Possible
- Insufficient supply or ground of the pump module Less likely
How to diagnose P069E
- Read every stored code with an OBD-II scanner. If misfire or fuel trim codes are there too, fix those first: they often cause this one.
- Inspect the parts involved: fuel pump control module, fuel pump, serial data line.
- Work through the causes above from most to least likely, cheapest checks first.
- Clear the code and drive a full drive cycle to confirm the repair held.

Questions drivers ask
Can I drive with code P069E?
Usually yes for a short time, if the car drives normally, the temperature gauge reads normal and the check engine light is steady. If the light flashes, the engine loses power or overheats, or other warning lights come on, pull over and have it checked.
Will my car pass an emissions inspection with P069E?
Probably not in states that test vehicles with an OBD-II scan: an emissions-related code that keeps the check engine light on is usually an automatic fail. Rules differ by state and county, so check yours.
Often reported together
Codes that owners mention in the same NHTSA complaints as P069E. They can point to a shared cause, so it's worth checking them together.
