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 109-13, 2802-13, or 5708-13 is active or logged.
Proceed to Test Step 3.
Result: Any other 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
Note: Some applications may be equipped with a breather element on the atmospheric pressure sensor. Inspect the breather element for plugging, along with the sensor port.
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
