P069EFuel Pump Control Module Requested MIL Illumination
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- 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. 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.
- What you may notice
- Check engine light on
- Possibly hard start, stumbling or lack of power from fuel supply problems
- Further codes stored in the fuel pump module
- Likely causes
- LikelyFault in the fuel pump circuit (pump, wiring, ground) stored in the pump module
- PossibleFuel pressure sensor or its wiring or 5 V reference
- PossiblePump module faulty internally or overheated (corrosion, moisture)
- RareInsufficient supply or ground of the pump module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
