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.

Troubleshooting Test Steps Values Results
1. Engine Derate or Active Codes
A. Certain diagnostic codes and/or event codes may cause poor performance. Refer to the histogram information for engine derates in the electronic service tool. Check for the following histograms:
1. High Exhaust Temperature Prevention Derate Time Histogram
2. High Turbo Speed Prevention Derate Time Histogram
B. If the histograms contain derates and no diagnostic codes are present, then the engine is operating normally. The following list contains conditions that can cause derates:
1. Elevated altitude
2. Elevated inlet air temperature
3. Elevated ambient temperature
Engine Derate or Active Codes
Result: A diagnostic code is present.
Repair: Troubleshoot the code and then reset the histogram.
Result: A diagnostic code is not present.
Proceed to Test Step 2.
2. Incorrect Parameters
A. Use the electronic service tool 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.
Repair: Input the correct parameters. Refer to Troubleshooting, "Configuration Parameters" for additional information.
3. Oil Pressure
Note: When the engine is started, the turbocharger protection strategy will lock the engine speed at low idle until the oil pressure builds or the engine has been running for 60 seconds.
A. Ensure that the engine oil pressure is sufficient. Refer to Troubleshooting, Oil Pressure Is Low.
Oil pressure
Result: The oil pressure is not OK.
Repair: Make any necessary repairs. Refer to Troubleshooting, Oil Pressure Is Low.
Result: The oil pressure is OK.
Proceed to Test Step 4.
4. Throttle Signal
A. Monitor the status for "Throttle Position" on the electronic service tool. 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 5.
Result: The throttle signal is not stable.
Repair: Make the necessary repairs, Refer to the appropriate circuit test.
5. Restriction in the Air Inlet and Exhaust System
A. Observe the check engine lamp.
B. Check for an air filter restriction indicator, if equipped.
C. Check for ECM codes for inlet air restriction:
107-15: Engine Air Filter 1 Differential Pressure high - least severe (1)
107-16: Engine Air Filter 1 Differential Pressure high - moderate severity (2)
D. Replace any plugged air filters. Refer to the Operation and Maintenance Manual.
E. Check the air inlet and exhaust system for restrictions and/or leaks.
Restrictions
Result: There are no restrictions in the air inlet or exhaust system.
Proceed to Test Step 6.
Result: There are restrictions in the air inlet or exhaust system.
Repair: Make the necessary repairs, Refer to Systems Operation, Testing and Adjusting, "Air Inlet and Exhaust System - Inspect" for additional information.
6. Check the Intake Throttle Valve
A. Use the electronic service tool to perform the "Air System Motor Valve Verification Test".
Intake Throttle Valve
Result: The "Air System Motor Valve Verification Test" failed.
Repair: Troubleshoot any diagnostic codes that were generated. Refer to Troubleshooting, Diagnostic Trouble Codes.
Result: The turbocharger is OK. The "Air System Motor Valve Verification Test" passed.
Proceed to Test Step 7.
7. Turbocharger
Note: The turbocharger that is installed on the engine is a nonserviceable item. If any mechanical fault exists, then the faulty turbocharger must be replaced.
A. Ensure that the mounting bolts for the turbocharger are tight.
B. Check that the compressor blades rotate freely in the turbocharger.
C. Check that the oil drain for the turbocharger is not blocked or restricted.
D. Check that the compressor housing for the turbocharger is free of dirt and debris. Make sure that the housing is not damaged.
E. Check that the turbine housing for the turbocharger is free of dirt and debris. Make sure that the housing is not damaged.
F. Inspect the wastegate for damage and ensure that it is operating correctly. Refer to Systems Operation Testing and Adjusting, Turbocharger - Inspect.
Turbocharger
Note: Some oil residue/pooling may be seen, but this is not an indication that the turbo has failed. If the compressor and turbine blades are undamaged and rotate freely, it is likely the turbocharger is fault free.
Result: There is a fault on the turbocharger.
Repair: Replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
Result: There are no faults on the turbocharger.
Proceed to Test Step 8.
8. 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. 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 screen on the electronic service tool to verify that the engine has exited cold mode. Observe the reading for coolant temperature on the electronic service tool.
Refer to "Cold Mode Operation" within Systems Operation, Testing and Adjusting, "General Information".
F. Check the fuel quality. Refer to Systems Operation, Testing and Adjusting, "Fuel Quality - Test" for the proper procedure. Check the fuel tank for debris or foreign objects which may block the fuel supply.
G. Check for the proper operation of the fuel transfer pump. Refer to Systems Operation/Testing and Adjusting, "Fuel System" for test information.
Fuel system
Result: The fuel pressure is OK.
Proceed to Test Step 9.
Result: The fuel pressure is not OK.
Repair: Replace the
