The WIF or Water in Fuel Sensor is used to determine the presence of water in your diesel fuel or Gasoline. The WIF sensor indicates the presence of water in the fuel. KLM Performance strongly recommends the regular draining of your fuel filter to prevent damage to your engines fuel injection system. The WIF sensor indicates a high presence of water in the fuel filter housing. This indication of water sends a warning signal to the engines ECU or the vehicles Dash Board. The WIF is a standard sensor element used in today's high-pressure common rail engines to prevent Fuel injector damage.
The WIF sensor location is at the bottom of the OEM fuel filter housing. The fuel filter housing is used to contain the captured water from the fuel. When the water level reaches a certain point, the WIF sensor alerts you to the presence of water. The electronic control module provides a reference signal to the water-in-fuel sensor. When the water collected in the fuel filter covers the sensor probes, the water-in-fuel sensor then alerts you of a high water accumulation in the fuel filter
Water is diesel fuel is a very common occurrence and must be addressed to prevent very costly repairs. The water gets into your diesel fuel from environmental conditions, high humidity, storage tanks and naturally occurring condensation. Regular draining of your fuel water separator is the most efficient way to control water in your fuel.
Water In Fuel Sensors are used in most diesel pickup trucks, medium duty, and Class 8 trucks, as well as Heavy Equipment and most diesel, powered engines.
The Water-in-fuel sensor is a fuel filter sensor which provides the illumination for alerting the driver of a water buildup in the fuel filter. This warning sign that must be addressed This warning light indication immediately tells you that there is excess water in your diesel fuel. The fuel filter housing or diesel fuel water separator filter should quickly be drained to remove the water. Removing the water from this fuel filter housing should remove the warning light. By practicing a regular schedule of draining the filter, you prevent expensive repairs, reduced engine performance, and fuel injection system durability problems.
