P2265 — Water in Fuel Sensor Circuit Range/Performance
The ECU detects that the water-in-fuel sensor signal is implausible compared to operating conditions. The reading does not change as expected during fuel filter purge or warm-up.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Water in fuel sensor
- Fuel filter housing
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Sensor drift or contamination
- Sensor element aged beyond calibration window
- Sensor mounting loose - signal damping
Diagnostic notes
- The malfunction indicator lamp may illuminate

Check each reference's vehicle and model-year scope. General background links do not establish which fault is most likely on your vehicle.
Diagnostic information is provided for reference only. Confirm the code with a compatible scan tool and follow the vehicle manufacturer's service procedures before replacing components.
