Water in Fuel Sensor
Principle
The Water In Fuel sensor (WIF Sensor) is used
to detect water in the fuel filter.
Water sensor fixed on the bottom side of the
filter bowl. The water molecules present in the
fuel is collected in the bottom of the filter
bowl. When the water level reaches a pre
defined level, the resistivity changes. This
change of resistivity is sensed by ECU and ECU
generates an alarm and sends appropriate
signals to other circuitry.
