Information:
Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes. Check Caterpillar Electronic Technician (ET) for any associated codes that are listed in Table 1. Troubleshoot any active codes before continuing with this procedure.Probable Causes
Codes
Parameters
Throttle Signal
Air Inlet and Exhaust System
Fuel System
Intake manifold pressure sensor
Flash file
Valve LashRecommended Actions
Note: The procedures have been listed in order of probability. Complete the procedures in order.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.
Table 1
Troubleshooting Test Steps Values Results
1. Engine Derate or Active Codes
A. Certain diagnostic and/or event codes can cause poor performance. Engine Derate or Active Codes
Result:
Active diagnostic codes are present
Troubleshoot the active codes
Result: Active diagnostic codes are NOT present
Proceed to Test Step 2.
2. Incorrect Parameters
A. Use Cat ET to verify that the correct parameters are being used. Refer to Troubleshooting, "Configuration Parameters" for additional information.
Parameters
Result: The parameters are correct.
Proceed to Test Step 3.
Result: The parameters are not correct.
Input the correct parameters. Refer to Troubleshooting, "Configuration Parameters" for additional information.
3. Throttle Signal
A. 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.
Throttle Signal
Result: The throttle signal is stable.
Proceed to Test Step 4.
Result: The throttle signal is not stable.
Make the necessary repairs, Refer to the appropriate circuit test.
4. Check the Fuel System
Refer to Systems Operation/Testing and Adjusting, "Fuel System" for additional information.
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the vent in the fuel cap is not filled with debris.
C. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
D. Inspect the fuel system. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
E. Check for the proper operation of the fuel transfer pump. Refer to Systems Operation/Testing and Adjusting, "Fuel System" for test information.
F. Perform the “Injector Solenoid Test” on Cat ET in order to determine if all of the injector solenoids are being energized by the ECM.
G. Perform the “Cylinder Cutout Test” on Cat ET in order to determine the performance of each cylinder. Refer to Troubleshooting, "Injector Solenoid - Test" for the proper procedure.
Fuel system
Result: The fuel pressure is OK.
Proceed to Test Step 6.
Result: The fuel pressure is not OK.
Replace the fuel filters. Clean the primary filter/water separator of debris. Refer to the Operation and Maintenance Manual for details.
4. Fuel Quality
F. Check fuel quality. Refer to Systems Operation/Testing and Adjusting, "Fuel Quality - Test" for the proper procedure.
Cold weather adversely affects the characteristics of the fuel. Refer to the engines Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation. Cold mode (if applicable) is activated whenever the engine coolant temperature falls below a predetermined value. Monitor the status
