Troubleshooting Test Steps Values Results
1. Check for Engine Derate or Codes
A. Certain codes may cause poor performance. Refer to the histogram information for engine derates in Cat ET. 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 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 Codes
Result: A code is not present.
Proceed to Test Step 2.
Result: A code is present.
Repair: Troubleshoot the code and then reset the histogram.
2. Check for 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.
Repair: Input the correct parameters. Refer to Troubleshooting, "Configuration Parameters" for additional information.
3. Monitor the 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.
Repair: Make the necessary repairs. Refer to the appropriate procedure.
4. Inspect for Restrictions in the Air Inlet and Exhaust System
A. Check for an air filter restriction indicator. Replace any plugged air filters. Refer to the Operation and Maintenance Manual.
B. 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 5.
Result: There are restrictions in the air inlet or exhaust system.
Repair: Make the necessary repairs, Refer
