What these codes mean
P2264–P2268 concern the water-in-fuel sensing circuit: general circuit, range/performance, low, high and intermittent respectively. P2269 is the water-in-fuel condition report. Preserve this distinction while matching the full code, controller and installed fuel system. A condition report is not an independent laboratory analysis, and a circuit category does not prove the fuel is clean.
A water-in-fuel warning requires the actual vehicle’s response instructions. The Ford 2014 Super Duty diesel supplement, for example, says to stop and shut off when its warning appears while the engine is running and warns of injection-system damage. Normal running does not establish suitable fuel or a harmless remaining journey. That owner example does not prescribe a separator design or draining method for another diesel.
Assess fuel condition and the sensing system as related but separate tasks. GM’s October 2024 bulletin 24-NA-225 includes P2264 among reported diesel-contamination codes and calls for the prescribed fuel-sample assessment before further diagnosis. A connector or electrical finding does not automatically settle whether contaminated fuel also needs attention.
Electrical and service examples also need their stated limits. Ford 18-2133 concerns some 2017–2018 Super Duty 6.7L vehicles built on or before 15 March 2018, P2266/P2269 and moisture at a specified connector. Stellantis STAR S2508000081, September 2025, describes P2267/P2269 and a warning remaining after filter-module draining. Neither is a universal sensor-replacement, connector-location or no-parts-repair rule.
Range/performance does not certify intact wiring, low does not select one failed part, high does not prove dry fuel or a two-wire open, and intermittent does not specify fault duration or recovery. An unplugged display or cleared warning cannot establish the fuel condition or the health of the complete circuit. Use the matched diagnostic state and signal interpretation.
Save the complete scan, warning behavior, recent refueling and filter-service details. Have qualified personnel use the prescribed fuel-handling precautions, contamination assessment and protected electrical/component tests. Do not open unidentified fuel plumbing, drain or prime a system by a generic recipe, energize a sensor or recreate an intermittent fault with connected probes on the road.
Correct the demonstrated cause and verify the sensing system and warning as specified. Filter, separator, sensor, conductor and contamination repairs require different findings. Request a vehicle-specific estimate covering the confirmed work and its verification. The code alone cannot establish a harmless water quantity, a fixed safe travel distance or which part should be ordered.
Identify the circuit on your vehicle
Match the full DTC, reporting module, and any failure-type suffix to the service information for your exact year, make, model, engine, and equipment. An identifier alone does not establish installed hardware count, location, connector pinout, or a universal measurement.
Where the manufacturer publishes its own meaning for this code, that is the one to work from — it describes the actual component on your vehicle, which the generic definition cannot. Keep the generic description for what it is good for: it tells you which subject area the standard assigned the code to, which is useful context when the two appear to disagree. If they do disagree, follow the manufacturer.
