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. Test the Fuel Injectors
A. Connect Cat ET.
B. Use Cat ET to perform the following fuel injector tests:
- "Injector Solenoid Test"
- "Cylinder Cutout Test"
- "Solenoid Valve -Test (Gas Admission Valve)"
Refer to Troubleshooting, "Cat ET Service Features" for additional information.
Fuel Injectors
Result: The tests were successful.
Proceed to Test Step 3.
Result: The tests were not successful.
Repair: Diagnose the problem. Repair or replace damaged components.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Torque of the In Cylinder Pressure Sensor (ICPS) Sensor
A. Turn the keyswitch to the OFF position.
B. Disconnect the ICPS adapter harness from the pressure sensor.
C. Check the ICPS torque value.
Note: Low sensor tor
