P2269Water in Fuel Condition - Sensor A
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2269 is not a wiring fault but a statement about the fuel: sensor A has detected water. On diesels it means the separator is full; Ram's 2025-26 Cummins 6.7L trucks set it with the MIL, and Stellantis traced a persistent case to incomplete draining, fixed by draining and swapping the sensor's signal and ground pins (TSB 14-004-26). Ford tied P2269 on 2017-18 Super Duty 6.7L trucks to water in connector C3080 and, in other bulletins, to PCM software. GM uses P2269 on flex-fuel petrol engines: if the flex fuel sensor's frequency exceeds 185 Hz in 50 of 63 samples, the fuel's conductivity points to water; Type B in 2018, Type A in 2025. Drain or replace contaminated fuel promptly; water damages injection pumps.
- What you may notice
- Water-in-fuel lamp or message, on some vehicles also the MIL
- Rough running, power loss or hard starting if water reaches the injection system
- Reduced power on some engines to protect the injection system
- Likely causes
- LikelyWater separator full and not drained at the service interval
- PossibleFuel from the tank or filling station containing water
- PossibleResidual water after draining or a wet sensor connector faking the alarm
- RareEngine control software needing an update
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €0 – €400
