Typical view of the pin location on the P1 connector for the WIF sensor (30) WIF sensor signalTest Step 1. Inspect Electrical Connectors And Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the connector for the WIF sensor and the P1/J1 ECM connector. Refer to Troubleshooting, "Electrical Connectors - Inspect"
Perform a 30 N (10 lb) pull test on each of the wires that are associated with the WIF sensor.
Check the harness for abrasions, for pinch points, and for corrosion.Expected Result:All connectors, pins, and sockets are correctly connected. The harness is free of corrosion, of abrasion, and of pinch points.Results:
The connectors and wiring appear to be OK - Proceed to Test Step 2.
There is a fault in the connectors and/or wiring. - Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are correctly installed and ensure that the connectors are correctly connected.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position.
Wait for at least 1 minute.
Monitor the active diagnostic code screen on the electronic service tool. Check and record any active diagnostic codes.Results:
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.
A 97-15 diagnostic code is not active at this time. - If the WIF sensor is not operating correctly, proceed to Test Step 5.Test Step 3. Disconnect the WIF Sensor
Turn the keyswitch to the OFF position.
Disconnect the WIF sensor from the harness.
Turn the keyswitch to the ON position. Wait for at least 1 minute.
Use the electronic service tool to check for an active 97-15 diagnostic code.Results:
The code disappears with the sensor disconnected. - The fault is in the sensor.Repair: Replace the WIF sensor. Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.STOP
A 97-15 diagnostic code is still active with the sensor disconnected. - The WIF sensor is OK Reconnect the sensor and proceed to Test Step 4.Test Step 4. Check the Sensor Signal Wire for a Short Circuit
Turn the keyswitch to the OFF position.
Disconnect the WIF sensor connector. Disconnect the P1 connector from the ECM.Thoroughly inspect the P1/J1 connectors for corrosion and/or damaged seals.
Use a suitable multimeter to check the resistance between P1:30 and all other terminals on the P1 connector.Expected Result:Each resistance measurement should be greater than 100 Ohms.Results:
OK - Each resistance measurement is greater than 100 Ohms. The wiring is OK.Repair: Perform the following repair:
Make sure that the latest flash file for the application is installed in the ECM. Refer to Troubleshooting, "Flash Programming".
Contact the Technical Communicator at a Caterpillar dealer.Note: This consultation can greatly reduce the repair time.
If the Technical Communicator recommends the use of a replacement ECM,
