Diagnostic Aids
WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Perform this test when directed by QUICK TEST. This test is only intended to diagnose the following components and circuits:
- WIF Sensor Output To Powertrain Control Module (PCM)
- WIF Sensor Wiring Harness Circuits
- PCM
The Water In Fuel (WIF) sensor is used to detect water in the fuel system and is located in the fuel filter housing. The WIF sensor is monitored by the PCM. If the PCM detects water for more than 5 seconds, it will set a continuous DTC P2269 and turn on the WATER IN FUEL Indicator Lamp (WIFIL). Route a hose from the fuel drain line to a 1-qt clear container. Start engine and open the fuel filter housing drain valve. Close the valve when you have filled the container. Inspect fuel in the container. If no water or contaminants are in the container, you may have a circuit fault.
