of the preceding diagnostic codes are active.Results:
OK - The diagnostic codes are not active. Proceed to Test Step 2.
Not OK - One of the diagnostic codes is active.Repair: Perform the following diagnostic procedure: Troubleshooting, "5 Volt Engine Pressure Sensor Supply Circuit - Test".STOPTest Step 2. Inspect Electrical Connectors And Wiring
Thoroughly inspect the J1/P1 ECM connector, the J2/P2 ECM connector, and any connectors that are associated with the suspect pressure sensor. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the sensor connectors that are associated with the active diagnostic code.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasion and for pinch points from the sensors back to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and the wiring appear to be OK. Proceed to Test Step 3.
Not OK - There is a problem with the connectors and/or the wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.Clear all logged diagnostic codes.STOPTest Step 3. Determine the Condition that is Present
Turn the key switch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Monitor the active diagnostic code screen on Cat ET.
Determine if the problem is related to an open circuit diagnostic code or to a short circuit diagnostic code.Expected Result:Either an open circuit diagnostic code or a short circuit diagnostic code is active.Results:
Short Circuit - A short circuit diagnostic code is active at this time. Proceed to Test Step 4.
Open Circuit - An open circuit diagnostic code is active at this time. Proceed to Test Step 7.Test Step 4. Disconnect the Suspect Sensor
