Troubleshooting Test Steps Values Results
1. Check for Codes
Note: The engine coolant temperature must be greater than 0° C (32° F) before beginning this procedure.
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check for Debris
A. Turn the keyswitch to the OFF position.
B. Check the sensor for debris.
C. If applicable, check the reference sensor for debris.
D. Check the sensor measurement port for blockage by debris.
E. If debris is found, clear the debris from the measurement port and replace the sensor.
F. Connect Cat ET.
G. Use Cat ET to monitor the following:
- Codes
Debris
Result: The sensor measurement port is not blocked by debris.
Proceed to Test Step 3.
Result: A -13 code is not active.
Return to service.
Result: A -13 code is active.
Repair: Replace the sensor. If more than one -13 code is active and the codes have a reference sensor, replace the reference sensor.
If the problem is not resolved, proceed to Test Step 3.
3. Inspect the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Inspect the sensor connector for moisture and corrosion.
Moisture
Result: The sensor connector does not have moisture or corrosion.
Proceed to Test Step 5.
Result: The sensor connector has moisture and/or corrosion.
Proceed to Test Step 4.
4. Remove any moisture and/or corrosion
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor connector.
C. Remove any moisture and/or corrosion from the outside of the connector. Check for moisture and corrosion inside the connector. Verify that the seals for the wires are sealing correctly. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information.
D. If necessary, repair or replace the connector.
E. Reconnect the connector. Verify that the connection is secure.
F. Connect Cat ET.
G. Use Cat ET to monitor the following:
- Codes
Moisture
Result: A -13 code is not active.
Return the service.
Result: A -13 code is active.
Repair: Replace the sensor. If more than one -13 code is active and the codes have a reference sensor, replace the reference sensor.
If the problem is not resolved, proceed to Test Step 5.
5. Check for Moisture and/or Corrosion in the Circuit
A. Turn the keyswitch to the OFF position.
B. Check all the connectors in the circuit for moisture and/or corrosion.
C. Check for corrosion inside the connector. Verify that the seals for the wires are sealing correctly. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information.
D. If necessary, repair or replace the connector.
E. Reconnect the connector. Verify that the connection is secure.
F. Connect Cat ET.
G. Use Cat ET to monitor the following:
- Codes
Moisture
Result: A -13 code is not active.
Return the service.
Result: A -13 code is active.
Repair: Replace the sensor. If more than one -13 code is active and the codes have a reference sensor, replace the reference sensor.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
