Water In Fuel Indicator: Description and Operation

Water-in-Fuel Indicator






The water-in-fuel indicator is controlled by the instrument cluster. The cluster receives electronic information from the PCM through the standard corporate protocol (SCP) communication network (Excursion) or the controller area network (CAN) (F-Super Duty or E-Series). If the water-in-fuel sensor indicates that there is water in the fuel separator/housing (located within the fuel condition module), the PCM sends a message to illuminate the water-in-fuel indicator.
