P2267
Water in Fuel Sensor A Circuit High
Fuel & air metering (diesel)
Generic OBD-II
Low
What it means
P2267 means the diesel water-in-fuel (WIF) sensor circuit is reading a higher voltage than expected. This sensor warns you when water collects in the fuel/water separator. The code is usually a wiring, connector, or sensor fault rather than an engine problem — the engine keeps running normally, but the water warning may not work until it's fixed.
Low
Can I keep driving? Usually fine to drive — the engine runs normally, but the water-in-fuel warning may not work, so check the fuel/water separator soon.
Common symptoms
What you'll notice
- Check-engine light on
- Water-in-fuel warning lamp stuck on, or not working at all
- No obvious change in how the engine runs
Common causes
Most likely first
- Corroded or loose connector at the water-in-fuel (WIF) sensor on the fuel filter/separatorLikely
- Wiring short to voltage or open in the sensor circuitCommon
- Failed water-in-fuel sensorCommon
- Water actually present in the fuel/separator affecting the signalLess often
- Failed PCM/ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Inspect the WIF sensor connector on the fuel filter housing for corrosion, water intrusion, or a loose pin.
- Drain the fuel/water separator and check for water contamination.
- Backprobe the sensor signal wire and compare voltage against spec; check the circuit for a short to voltage or an open.
- Test the sensor's resistance; replace the sensor if out of range.
- If wiring and sensor are good, suspect the ECM. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2267?+
Generally yes — the engine itself runs normally. But the fault means the water-in-fuel alarm may be disabled, so check the water separator and get the circuit fixed to stay protected.
Can I just clear P2267?+
You can, but it returns until the sensor, connector, or wiring is repaired. Clear it after fixing to confirm the repair held.
