DESCRIPTION
The water in fuel sensor (WIF) is located in the fuel filter housing (4). The WIF sensor (3) detects the presence of water in the fuel. If water is present in
the fuel, a signal is sent to the ECM and the ECM signals the instrument cluster, over the CAN bus, to illuminate the water in fuel warning.
