Diagnostic Trouble Code for the Water-in-Fuel Sensor
J1939 Code Code Description Comments
97-3 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 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.
Note: The keyswitch must have been in the "OFF" position for at least 15 seconds to enable the 97-3 diagnostic check. The 97-3 diagnostic check only occurs once in a keycycle, immediately after the keyswitch is turned to the "ON" position.
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 5 seconds, a 97-15 diagnostic code will become active. If the signal remains constant for 30 minutes, a 97-16 diagnostic will become active. These diagnostic codes can also be caused by a short in the WIF sensor circuit.

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 any interface connectors between the WIF sensor and the ECM connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a 30 N (6.7 lb) pull test on each of the wires in the WIF sensor connector and any interface connectors that are associated with the WIF sensor.
D. Check the harness for abrasions, for pinch points, and for corrosion.
Note: Do not disconnect the ECM connector at this stage. The ECM can only be disconnected and reconnected 10 times before damage to the harness connector may occur.
Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all the seals are properly in place and ensure that the connectors are correctly coupled.
