TRANSFORMER 3619096 - Caterpillar

Probable Causes
Air inlet and exhaust system
Engine speed/timing sensor
Atmospheric pressure sensor
Intake manifold (boost) pressure sensor
"Fuel Position" and/or "FRC Fuel Limit"
Flash file
Fuel quality
Valve adjustmentRecommended Actions
Air Inlet and Exhaust System
Check the air inlet system for restrictions and/or for leaks.
Check for an air filter restriction.
Check for derates and for alarms.
Perform a visual inspection of the system for restrictions and/or for leaks.
Ensure that the turbocharger has not failed.
Check the exhaust system for restrictions.
Repair any leaks that were found. Remove any restrictions that were found. Replace any damaged components that were found.Engine Speed/Timing
Check the calibration of the engine speed/timing sensor. Refer to calibration procedures Troubleshooting, "Engine Speed/Timing Sensor - Calibrate".
Verify that the crankshaft and the camshaft drive gears are set with the proper orientation. Refer to the Disassembly and Assembly manual.Atmospheric Pressure Sensor
Check the atmospheric pressure sensor for dirt and/or for debris. Remove any dirt and/or debris that is present. The correct reading for the atmospheric pressure is between 50 kPa (7.25 psi) and 100 kPa (14.5 psi).Intake Manifold (Boost) Pressure Sensor, "Fuel Position", and/or "FRC Fuel Limit"
Monitor the status of "Fuel Position" and "Rated Fuel Limit" while the engine is operating under full load. If "Fuel Position" equals "Rated Fuel Limit" and "Fuel Position" is less than "FRC Fuel Limit", the electronics are operating correctly. Otherwise, proceed to the next Step.
Verify that there are no active diagnostic codes for the intake manifold (boost) pressure sensor.
Monitor the status of "Intake Manifold (Boost) Pressure" and "Atmospheric Pressure" for normal operation on the Caterpillar Electronic Technician (ET). When the engine is not running, "Intake Manifold (Boost) Pressure" should be 0 kPa (0 psi).Note: A problem with the FRC will only cause black smoke during acceleration. A problem with the FRC will not cause black smoke during steady state operation.Flash File
Verify that the correct flash file is installed. Refer to programming parameters Troubleshooting, "Flash Programming".Fuel Quality
Cold weather adversely affects the characteristics of the fuel. For information on improving the characteristics of the fuel during cold weather operation, refer to the Operation and Maintenance Manual.Valve Adjustment
Check the valve adjustment. Refer to Systems Operation/Testing and Adjusting.
