Troubleshooting Test Steps Values Results
1. Check for Codes
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 High Intake Manifold Temperature
Note: A 1 degree increase in the intake manifold temperature will increase the exhaust temperature by approximately 3 degrees.
A. Refer to Troubleshooting, "Intake Manifold Air Temperature Is High" for additional information.
Temperature
Result: The intake manifold temperature is OK.
Proceed to Test Step 3.
Result: The intake manifold temperature is NOT OK.
Repair: Determine
