Information:
the electrical power from the ECM.
Disconnect the harness connectors for the following sensors:
Injection actuation pressure sensor
Intake manifold (boost) pressure sensor
Atmospheric pressure sensor
Fuel pressure sensor
Engine oil pressure sensor
Turbo inlet air pressure sensor
Restore the electrical power to the ECM.
Measure the voltage between terminals A (+5 VDC) and B (Return) at each sensor connector on the engine harness.
Remove the electrical power from the ECM.
Connect all of the sensors. Expected Result:Each voltage measurement is 5.0 0.2 VDC.Results:
OK - Each voltage measurement is 5.0 0.2 VDC. Proceed to Test Step 3.
Not OK - At least one voltage measurement is not 5.0 0.20 VDC.Repair: Refer to the diagnostic functional test Troubleshooting, "5 Volt Engine Pressure Sensor Supply Circuit - Test".STOPTest Step 3. Check for Active Diagnostic Codes
Connect the Caterpillar Electronic Technician (ET) to the service tool connector. Refer to electronic troubleshooting Troubleshooting, "Electronic Service Tools".
Restore the electrical power to the ECM.
Observe the "Active Diagnostic" screen on Cat ET. Wait at least 30 seconds so that any codes may become active. Look for an active diagnostic code for an engine pressure sensor.
Determine if the problem is related to a 03 diagnostic, a 04 code, or a 10 diagnostic code. Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active for the engine pressure sensors.Repair: If any of the above codes are logged and the engine is not running properly, refer to troubleshooting without a diagnostic code Troubleshooting.If the engine is running properly at this time, there may be an intermittent problem in a harness that is causing the codes to be logged. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".STOP
Active 04 code - An
