Troubleshooting Test Steps    Values    Results    
1. Check for Diagnostic Trouble Codes
The engine coolant temperature must be greater than
0° C (32° F) before beginning this procedure.
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Wait at least 30 seconds in order for the diagnostic codes to become active.
Look for an active -13 code or for a logged -13 code.
   
Diagnostic Trouble Codes    
Result: There is an active or there is a logged -13 code.
Proceed to Test Step 2.
   
2. Check for Debris
A. Turn the keyswitch to the OFF position.
B. Check the suspect 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 suspect sensor.
F. Turn the keyswitch to the ON position.
G. Check for -13 codes. Wait at least 30 seconds in order for the diagnostic codes to become active.
The 2458-13 will not activate for several hours if the ambient temperature is below
7° C (45° F) or if an active regeneration has not been performed. If troubleshooting a 2458-13 and ambient temperature is below
7° C (45° F), perform a "Manual DPF regeneration" after completing the repair to verify that the problem has been resolved.
   
Debris    
Result: The sensor measurement port is not blocked by debris.
Proceed to Test Step 3.
Result: A -13 code is not present, return the unit to service.
Result: A -13 code is present, replace the suspect sensor. Verify that the problem is resolved.
Result: If more than one -13 code is present and the codes have a reference sensor, replace the reference sensor. Verify that the problem is resolved.
   
3. Inspect the Suspect Sensor Connector
A. Turn the keyswitch to the OFF position.
Inspect the suspect sensor connector for moisture and/or corrosion.
   
Moisture    
Result: The suspect sensor connector has moisture and/or corrosion.
Proceed to Test Step 4.
Result: The suspect sensor connector does not have moisture and/or corrosion.
Proceed to Test Step 5.
   
4. Remove any moisture and/or corrosion
A. Disconnect the suspect sensor connector.
B. 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", if necessary.
C. If necessary, repair the connector or replace the connector.
D. Reconnect the connector. Verify that the connection is secure.
E. Turn the keyswitch to the ON position.
F. Monitor the diagnostic codes on Cat ET. Check for -13 codes. Wait at least 30 seconds in order for the diagnostic codes to become active.
The 2458-13 will not activate for several hours if the ambient temperature is below
7° C (45° F) or if an active regeneration has not been performed. If troubleshooting a 2458-13 and ambient temperature is below
7° C (45° F), perform a "Manual DPF regeneration" after completing the repair to verify that the problem has been resolved.
   
Moisture    
Result: A -13 code is not present, return the unit to service.
Result: A -13 code is present, replace the suspect sensor. Verify that the problem is resolved.
Result: If only a 289-13 code is present, replace the reference sensor. Verify that the problem is resolved.
Result: If only a 460-13 or 5580 -13 code is present, replace the reference sensor. Verify that the problem is resolved.
Result: If more than one -13 code is present and the codes have a reference sensor, replace the reference sensor. Verify that the problem is resolved.
