The water-in-fuel sensor (WIF) is utilized to calculate the amount of water in diesel fuel or gasoline. The WIF sensor detects if there is any water in the fuel.
Water-in-fuel sensor significanceThe WIF sensor is placed under the fuel filter housing which is utilized to contain the captured water from the fuel. When water has reached a certain limit, the WIF sensor lets you know the presence of water. Water contamination can be found in diesel fuel and it is important that it is detected with the help of the WIF sensor and removed as soon as possible to conserve the fuel injection system. It is important to maintain the sensor in good condition to alert you when there is water in the fuel.
