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. Establish communication between Cat® Electronic Technician (Cat ET) Service Tool and the Electronic Control Module (ECM).
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.
Note: Look for an active -13 code or for a logged -13 code.
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 OFF.
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 ON.
G. Check for -13 codes. Wait at least 30 seconds in order for the diagnostic codes to become active.
Note: The 3251-13 will not activate if the ambient temperature is below 7° C (45° F) or an active regen has not been performed. If troubleshooting a 3251-13 and the ambient temperature is below 7° C (45° F), perform a "Manual DPF regeneration". Completing the "Manual DPF regeneration" will 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
