Information:


Illustration 1 g01124872
Map for the fuel pressureSystem Response:The ECM will log the warning. The ECM will transmit a warning to the display in the cab. The ECM will reset the warning when the fuel pressure rises 10 kPa (1.5 psi) above the low pressure trip line for four seconds.
Low powerTest Step 1. Replace the Fuel Filter
Replace the fuel filter. Refer to the Operation and Maintenance Manual for the procedure.
Start the engine and verify that the event is no longer active.Expected Result:Replacing the fuel filter corrected the problem.Results:
OK - Replacing the fuel filter corrected the problem.STOP
Not OK - Replacing the fuel filter did not correct the problem. Proceed to Test Step 2.Test Step 2. Verify Proper Sensor Installation
Check the installation of the fuel pressure sensor.
Check the wiring of the fuel pressure sensor. Refer to the Electrical Schematic for the proper wiring. Ensure that all of the wires and connectors are properly connected.Expected Result:The sensor is properly installed and the wiring is correct.Results:
OK - The sensor is properly installed. Proceed to Test Step 3.
Not OK - The sensor is not installed properly.Repair: Install the fuel pressure sensor properly. Repair the wiring and/or the connectors to the sensor.Verify that the repair eliminates the problem.STOPTest Step 3. Check for Active Diagnostic Codes
Connect the Caterpillar Electronic Technician (Cat ET) to the service tool connector.
Check for active diagnostic codes that are related to the atmospheric pressure sensor and/or to the turbocharger outlet pressure sensor.Expected Result:No diagnostic codes are related to the atmospheric pressure sensor and/or to the turbocharger outlet pressure sensor.Results:
OK - There are no diagnostic codes. Proceed to Test Step 4.
Not OK - There is a diagnostic code that is related to the atmospheric pressure sensor and/or the turbocharger outlet pressure sensor.Repair: Troubleshoot the diagnostic code before continuing with this procedure.STOPTest Step 4. Check the Status Screen
Turn the keyswitch to the ON position. The engine should be off.
Monitor the status for "Boost Pressure" and "Fuel Pressure" on Cat ET.Expected Result:"Boost Pressure" and "Fuel Pressure" are less than 10 kPa (2 psi).Results:
OK - The boost pressure and the fuel pressure are less than 10 kPa (2 psi). Proceed to Test Step 6.
Not OK - Boost Pressure - The boost pressure is greater than 10 kPa (2 psi). Proceed to Test Step 8.
Not OK - Fuel Pressure - The fuel pressure is greater than 10 kPa (2 psi). Proceed to Test Step 9.
Not OK - Both - The boost pressure and fuel pressure are greater than 10 kPa (2 psi). Proceed to Test Step 5.Test Step 5. Check the Supply Voltage to the Pressure Sensors
Disconnect the atmospheric pressure sensor, the fuel pressure sensor, and the turbocharger outlet pressure sensor.
Turn the keyswitch to the ON
