P2268Water in Fuel Sensor A Circuit Intermittent
- Generic OBD-II code · Powertrain
- How the car detects it
- P2268 is reserved for a water-in-fuel sensor A circuit whose signal drops out or jumps for short moments instead of staying at a fault level. No manufacturer documents P2268 publicly. The neighbouring codes show where such faults arise on real trucks: Ford traced P2266 on 6.7L Super Duty models to water entering the sensor connector, and Stellantis linked P2267 on Cummins Ram trucks to residue on the probes after draining. Both effects can come and go with temperature, vibration or fuel sloshing in the filter, which is the typical picture of an intermittent circuit. The sensor itself is a simple pair of electrodes, so the search starts at connector, terminals and harness clips. P2266 and P2267 are the steady low and high faults.
