Basic error definition

Water In Fuel Sensor B Circuit Low

Cause of DTC

There are two Water-In-Fuel (WIF) sensors attached to the two fuel filters. WIF 1 is attached to the fuel filter mounted on the engine. WIF 2 is attached to a 2nd fuel filter that can now be found mounted to the chassis. The Powertrain Control Module (PCM) provides a 5-Volt reference signal to each WIF sensor. When the water collected in the respective fuel filter covers the sensor probes, the sensor then pulls the 5-Volt reference voltage low indicating high water accumulation in that fuel filter. Starting with the 2016 Model Year, the two WIF sensors will have separate DTCs to distinguish which sensor has faulted.
