LINING GP- 8Y6307 - Caterpillar

not running properly, refer to Troubleshooting, "Troubleshooting without a Diagnostic Code". If the engine is running properly at this time, an intermittent condition may be causing the logged codes. Refer to Troubleshooting, "Electrical Connectors - Inspect". STOPTest Step 2. Inspect Electrical Connectors and Wiring
Thoroughly inspect the J1/P1 ECM connector, the J2/P2 ECM connector, the suspect sensor connector, and any other connectors in the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the sensor connector and in the ECM connector that are associated with the active diagnostic code.
Verify that the latch tab of the connector is properly latched.
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 abrasions and for pinch points from the sensor to the ECM.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and the 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.STOPTest Step 3. Verify that the Diagnostic Code is Still Active
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Access the "Active Diagnostic Codes" screen on Cat ET and check for active diagnostic codes.
Determine if the problem is related to an open circuit diagnostic code or to a short circuit diagnostic code.Expected Result:A short circuit diagnostic code or an open 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 6.
No Active Diagnostic Codes - There may be an intermittent problem in the connectors and/or in the wiring.Repair: Carefully reinspect the connectors and wiring. The diagnostic code will probably reoccur. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information.STOPTest Step 4. Disconnect the Sensor in Order to Create an Open Circuit
Turn the keyswitch to the OFF/RESET position.
Disconnect the connector to the sensor with the short circuit diagnostic code.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Access the "Active Diagnostic Codes" screen on Cat ET and check for an active open circuit diagnostic code for the suspect sensor.Expected Result:An open circuit diagnostic code is now active for the disconnected sensor.Results:
OK - A short circuit diagnostic code was active before disconnecting the sensor. An open circuit diagnostic code became active after disconnecting the sensor. Proceed to Test Step 5.
Not OK - There is a short circuit between the sensor harness connector and
