Water in Fuel Sensor Circuit High
P2267 indicates the water in fuel sensor circuit is reading a voltage signal that is higher than the expected range. This code sets when the engine control module detects an abnormal signal from the water detection sensor in the fuel tank, which monitors for contamination.
What You Might Notice
- Check engine light illuminated
- Water in fuel warning light on
- Engine stalling or rough idling
- Severe misfiring and poor performance
- Engine difficulty starting
- Reduced fuel economy
Most Common Causes
- 1
Defective water in fuel sensor
The sensor itself may be faulty or failing, sending an out-of-range voltage signal to the ECU. This is the most common cause of this code.
- 2
Corroded or damaged sensor connector
Poor electrical connections at the water in fuel sensor plug can cause intermittent or high voltage readings. Corrosion and oxidation are frequent culprits.
- 3
Faulty or damaged wiring
Broken wires, damaged insulation, or pinched connectors in the sensor circuit harness can disrupt the signal to the ECU.
- 4
Contaminated fuel or water in fuel tank
Actual water or fuel contamination may trigger a legitimate sensor response, but if the signal persists after fuel replacement, the sensor itself is likely faulty.
How to Diagnose It
- 1
Check Defective water in fuel sensor — The sensor itself may be faulty or failing, sending an out-of-range voltage signal to the ECU. This is the most common cause of this code.
- 2
Check Corroded or damaged sensor connector — Poor electrical connections at the water in fuel sensor plug can cause intermittent or high voltage readings. Corrosion and oxidation are frequent culprits.
- 3
Check Faulty or damaged wiring — Broken wires, damaged insulation, or pinched connectors in the sensor circuit harness can disrupt the signal to the ECU.
- 4
Check Contaminated fuel or water in fuel tank — Actual water or fuel contamination may trigger a legitimate sensor response, but if the signal persists after fuel replacement, the sensor itself is likely faulty.
How to Fix It
- 1
Replace water in fuel sensor
Remove the fuel tank or access panel and replace the defective water detection sensor with an OEM or quality replacement. Clear the code after replacement and test drive to confirm resolution.
- 2
Inspect and clean sensor connector
Locate the water in fuel sensor connector, disconnect it, and clean both the male and female terminals with electrical contact cleaner. Reconnect firmly and apply dielectric grease to prevent future corrosion.
- 3
Check and repair wiring harness
Visually inspect the sensor wiring harness for cuts, breaks, or pinched areas. Repair or replace damaged sections using appropriate gauge wire and weatherproof connectors. Test continuity with a multimeter.
- 4
Drain fuel and replace fuel filter
If contaminated fuel is suspected, drain the fuel tank completely and replace the fuel filter. Refill with fresh, quality fuel and monitor for code recurrence.
