Diagnostic Trouble Code for the Water-in-Fuel Sensor
J1939 Code CDL code Code Description
(code descriptions may vary Comments
97-3 3547-3 Water In Fuel Indicator : 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 warning 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, a 97-15 (E232-1) diagnostic code will become active. If the signal remains constant for 1 hour, a 97-16 (E232-2) diagnostic code will become active. These diagnostic codes can also be caused by a short in the WIF sensor circuit.During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect the connector for the WIF sensor and the P1/J1 ECM connector. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a 45 N (10 lb) pull test on each of the wires that are associated with the WIF sensor.
D. Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in).
E. Check the harness for abrasions, for pinch points, and for corrosion.
Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors
