P2269
Water in Fuel Condition - Sensor A
Fuel system (diesel)
Generic OBD-II
High
What it means
P2269 means the water-in-fuel (WIF) sensor — usually mounted in the fuel filter or water separator on a diesel — has detected water in the fuel above the allowed level. Water doesn't lubricate like diesel and can corrode and damage the high-pressure injection pump and injectors, so it matters. The dash usually shows a "water in fuel" warning alongside the code.
High
Can I keep driving? Limited — drain the water separator promptly. Running with water in the fuel can cause rough running, hard starting, and expensive damage to the injection pump and injectors.

Most likely first

- Wiring or connector fault at the WIF sensorLess often
- Failed PCM/ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Drain the fuel/water separator using its drain valve, then recheck.
- If water keeps returning, suspect contaminated fuel and drain or replace the fuel filter.
- Test the water-in-fuel sensor and its wiring/connector for shorts or opens.
- Replace the WIF sensor if it reports water when the separator is dry.
- Clear the code and confirm it stays off over a few drive cycles.
FAQ
Quick answers
Is it safe to drive with P2269?+
Not for long. Drain the water separator as soon as possible — water in diesel fuel can damage the injection pump and injectors and cause running problems.
Can I just clear P2269?+
Clearing it without removing the water won't help; it returns as soon as the sensor sees water again. Drain the water first.
