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.Engine Derate and Active Codes
Certain diagnostic codes and/or event codes may cause poor performance. Refer to the histogram information for engine derates in Cat ET. If derates are indicated in the histogram, and no diagnostic codes are present, then the engine is operating normally. The following list contains conditions that can cause derates:
Elevated altitude
Elevated inlet air temperatureIf a diagnostic code is present, troubleshoot the code and then reset the histogram. Incorrect Parameters
Use Cat ET to verify that the configuration parameters are programmed correctly. Refer to Troubleshooting, "Configuration Parameters" for the proper information.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. If a problem is suspected with the throttle, refer to the appropriate circuit test for information that is related to troubleshooting the throttle signal.Restriction in the Air Inlet and Exhaust System
Observe the check engine lamp. Check for an air filter restriction indicator. Replace any plugged air filters. Refer to the Operation and Maintenance Manual.
Check the air inlet and exhaust system for restrictions and/or leaks. Refer to Systems Operation/Testing and Adjusting, "Air Inlet and Exhaust System" for details. Check the Fuel System
Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
Ensure that the vent in the fuel cap is not filled with debris.
Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
Inspect the fuel system. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
Cold weather adversely affects the characteristics of the fuel. Refer to the engine 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 screen on Cat ET in order to verify that the engine has exited cold mode. Observe the reading for coolant temperature on the Cat ET.
Check fuel quality. Check the fuel tank for debris or foreign objects which may block the fuel supply.
If the fuel pressure is low, replace the fuel filters. Clean the primary filter/water separator of debris. Refer to the Operation and Maintenance Manual for details. Also, check for the proper operation of the fuel transfer pump. Refer to Systems Operation/Testing and Adjusting, "Fuel System" for test information.Valve Lash
Check the valve lash. The valve lash can affect the performance of the engine. Refer to Testing and Adjusting, "Engine Valve Lash - Inspect/Adjust" for the correct procedure.Engine Load
Check for accessories and parasitic loads that are causing excessive loads on the engine.
