Diagnostic Trouble Code for the Water-in-Fuel Sensor    
CDL Code     Description     Notes    
3547-3     Water in Fuel System Switch : Voltage Above Normal     The ECM detects the following conditions:
An open circuit in the Water-In-Fuel (WIF) sensor circuit.
The ECM has been powered for less than 5 seconds.
The Engine System Indicator lamp will stay on when the "indicator lamp self check" has been completed. The ECM will disable the function to detect water in fuel while the code is active.    Water-in-Fuel Sensor OperationThe WIF sensor is a normally open sensor. During normal operation, there will be no signal sent from the WIF sensor to the ECM. If water is detected in the fuel, the sensor will send a signal to the ECM. If the signal remains constant for 45 seconds, an E232-1 diagnostic code will become active. This diagnostic code can also be caused by a
