Recommended Actions
Engine "Derated"
Use Caterpillar Electronic Technician (ET) to check for logged engine derates and/or for active engine derates. A derate status flag will appear on Cat ET if an engine derate is active. The engine may be derated due to one of the following conditions: high altitude, dirty air filters and other factors.Starting Aids
Cold Mode
Use Cat ET to verify that the engine has exited cold mode. Cold mode operation may slow throttle response.Air Inlet Heater (If Equipped)
Ensure that the air inlet heater is programmed to "On". Ensure that the air inlet heater is functioning properly. Refer to Troubleshooting, "Air Inlet Heater Circuit - Test" for additional information.Oil Grade Plugs (If Equipped)
Ensure that the correct oil grade plug is installed. Refer to Operation and Maintenance Manual for additional information.Personality Module (Flash File)
Verify that the correct personality module (flash file) is installed.Throttle Position Sensor
Monitor "Throttle Status" on Cat ET. Verify that the throttle position is stable and that the engine is able to reach high idle rpm. Refer to Troubleshooting, "Throttle Position Sensor Circuit - Test" for the proper troubleshooting procedure.Electrical Connectors
Check for correct installation of the J1/P1 and J2/P2 connectors on the Electronic Control Module (ECM) and on the unit injector connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".Circuit for Electronic Unit Injector
Use Cat ET to determine if there are any active diagnostic codes for the unit injectors.
Table 1
Diagnostic Codes for Injectors    
Cylinder Number     Flash Code     CID-FMI     SPN-FMI    
1     72     1-11     651-11    
2     72     2-11     652-11    
3     73     3-11     653-11    
4     73     4-11     654-11    
5     74     5-11     655-11    
6     74     6-11     656-11    
Perform the injector solenoid test on Cat ET in order to determine if all of the injector solenoids are being energized by the ECM.
Perform the cylinder cutout test on Cat ET in order to identify any injectors that might be misfiring. Refer to Troubleshooting, "Injector Solenoid Circuit - Test" for the proper procedure.Turbocharger Outlet Pressure Sensor (Intake Manifold Air), Rated Fuel Position and/or FRC Fuel Position
When the engine is operating under a full load, monitor "Fuel Position" and "Rated Fuel Limit" on the Cat ET status screen. If "Fuel Position" does not equal "Rated Fuel Limit" then check air inlet manifold pressure.
Verify that there are no active diagnostic codes that are associated with the turbocharger outlet pressure sensor (intake manifold air) or with the atmospheric pressure sensor.
Monitor air inlet manifold pressure and atmospheric pressure for normal operation on the Cat ET status screen.Note: Atmospheric pressure is not a default parameter on a Cat ET status screen. A new parameter screen must be set up in order to monitor the atmospheric pressure sensor.Air Inlet and Exhaust System
Check for an air filter restriction indicator. Clean plugged air filters or replace plugged air filters. Refer to the Operation and Maintenance Manual.
Check the air inlet and exhaust system for restrictions and/or for leaks. Refer to Testing and Adjusting, "Air Inlet and Exhaust System" for more information.Fuel Supply
Check the fuel lines for the following problems: restrictions, collapsed lines and pinched lines. If problems are found with the fuel lines, repair the lines and/or replace the lines.
Check the fuel tank for foreign objects which may block the fuel supply.
Check for air in the low pressure fuel supply system if any of the following procedures have been performed:
Replacement of the fuel filters
Service on the low pressure fuel supply circuit
Replacement of unit injectorsNote: A sight glass in the low pressure supply line is helpful in diagnosing air in the fuel. Refer to Testing and Adjusting, "Fuel System" for more information.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Purge air from the low pressure fuel supply circuit. Refer to Operation and Maintenance Manual, "Fuel System-Prime".
Check fuel quality. In temperatures below 0 °C (32 °F), check for solidified fuel (wax). Refer to Special Instruction, SEBD0717, "Diesel Fuels And Your Engine".
Check the fuel pressure after the fuel filter while the engine is being cranked. Refer to Testing and Adjusting, "Fuel System" for the correct pressure values. If the fuel pressure is low, replace the fuel filters. If the fuel pressure is still low, check the following items: fuel transfer pump, fuel transfer pump coupling and fuel pressure regulating valve. Refer to Testing and Adjusting for more information.
