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.
