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, “Electri-
cal Connectors - Inspect”.
C. Perform a 30 N (10 lb) pull test on each of the wires that
are associated with the WIF sensor.
D. Check the harness for abrasions, for pinch points, and for
corrosion.
Damaged wire
or connector
Result: A damaged wire or damaged connector was found.
Repair: Repair the damaged wire or the damaged connector.
Use the electronic service tool to clear all logged diagnostic co-
des. Verify that the repair eliminates the fault.
Result: All connectors, pins, and sockets are correctly con-
nected and/or inserted and the harness is free of corrosion, of
abrasion or of pinch points.
Proceed to Test Step 2.
2. Check for Active Diagnostic Codes
A. Connect the electronic service tool to the diagnostic
connector.
B. Turn the keyswitch to the ON position.
C. Wait for at least 1 minute.
D. Monitor the active diagnostic code screen on the electronic
service tool. Check and record any active diagnostic codes.
Diagnostic
codes
Result: A 97-15 diagnostic code is active.
Repair: Ensure that there is no water present in the fuel before
continuing with this procedure. Refer to Troubleshooting, “Fuel
Contains Water”.
Proceed to Test Step 3.
Result: A 97-15 diagnostic code is not active at this time.
If the WIF sensor is not operating correctly, proceed to Test
Step 5.
