Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged on the In Cylinder Pressure Sensor (ICPS) Electronic Control Module (ECM).
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 the Torque of the 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 torque may allow leakage and lower than expected cylinder pressures.
Torque
Result: The sensor was torqued to 11.5 1 N m (102 9 lb in).
Proceed to Test Step 3.
Result: The sensor was not torqued to 11.5 1 N m (102 9 lb in).
Repair: Torque the sensor to 11.5 1 N m (102 9 lb in).
