Information:
Probable Causes
Note: An erratic signal from the torque converter speed sensor can cause low power or the engine to cut out.
Active engine derate
Diagnostic codes
Event codes
Programmable parameters
Cold mode
Electrical connectors
Throttle signal
Circuit for electronic unit injectors
Injection actuation pressure
Fuel supply
Intake manifold (boost) pressure sensor
Air inlet and exhaust systemRecommended Actions
Note: If the problem only occurs under certain conditions, test the engine under those conditions. Examples of certain conditions are high engine speed, full load and engine operating temperature. Troubleshooting the symptoms under other conditions can give misleading results.Diagnostic Codes and Event Codes
Certain diagnostic codes and/or event codes may cause poor performance. Connect the Caterpillar Electronic Technician (ET) and check for active codes and/or logged codes. Wait at least 30 seconds in order for any codes to become active. Troubleshoot any codes that are present before continuing with this procedure.Note: Although a sensor's signal may be in the operational range of the sensor, certain failure modes of a sensor may produce an output signal that does not represent an accurate measurement. Use Cat ET to check that the pressures and the temperatures are fluctuating normally. Also check that the values are reasonable for the conditions that are present.Programmable Parameters
If the Electronic Control Module (ECM) has been replaced, compare the values on the engine information plate to the following parameters from Cat ET:
FRC offset
Full Load Setting (FLS)
Full Torque Setting (FTS)Determine the type of throttle that is used in the application. Program any parameters that may be associated with the throttle. Program any parameters that may be associated with this troubleshooting procedure.Note: If the parameters are not programmed correctly, then the engine will have poor performance.Cold Mode
Verify that the engine has exited cold mode. If the engine is operating in cold mode, an indicator will be displayed on the top of any of the status screens on the electronic service tool. Cold mode operation may slow throttle response.Electrical Connectors
Check the associated wiring for damage, for abrasion, for corrosion or for incorrect attachment on the following connectors: Electronic Control Module (ECM) connectors and customer connector. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".Throttle Signal
Monitor the status for "Throttle Position" on Cat ET. Verify that the status for "Throttle Position" is stable and that the engine is able to reach high idle speed. Refer to the appropriate diagnostic functional test for your application:
Troubleshooting, "Throttle Position Sensor Circuit - Test"
Troubleshooting, "Throttle Switch Circuit - Test"
Troubleshooting, "Speed Control - Test"Unit Injectors
Use Cat ET to perform the injector solenoid test 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 check the performance of each cylinder. Refer to the diagnostic functional test Troubleshooting, "Injector Solenoids Circuit - Test".Injection Actuation Pressure
Check the engine oil level. Engine oil supplies the injection actuation pressure circuit. The engine oil must be kept at the proper level for fuel injection.
If service has recently been performed on the engine, air may be present in the injection actuation
