DJ - Water In Fuel (WIF) Sensor

Input Function
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 P1140 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.
