Information:

Probable Causes
The probable root causes are listed in order below:
Electrical connections
Engine Monitoring
Battery power or ground to the ECM
Electronic system
Accelerator pedal position sensor
Vehicle speed signal
Power train data link
Fuel supply
Torque limit switch
Low injection actuation pressureRecommended Actions
Perform the following diagnostic procedures in order:Electrical Connectors
Check the vehicle harness and the connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".Engine Monitoring
Check the parameters for "Engine Monitoring".
Connect the electronic service tool to the cab data link connector.
Check for diagnostic codes that can derate the engine when "Engine Monitoring" is programmed to "Derate" or "Shutdown".
110-00 High Coolant Temperature Warning (61)
110-11 Very High Coolant Temperature (61)
111-11 Very Low Coolant Level (62)Battery Power or Ground to the ECM
Ensure that the following connectors have been installed correctly:
ECM connectors (J1/P1 and J2/P2)
Injector connector (J300/P300)
Camshaft position sensor connector (J401/P401 and J402/P402)
Use the electronic service tool to check for a diagnostic code 168-02 (Intermittent Battery Power to the ECM). Check the power connections for the ECM and the ground connections for the ECM. If a problem is suspected, wire a bypass. Refer to Troubleshooting, "Ignition Key Switch Circuit and Battery Supply Circuit - Test"(51).Electronic System
Connect the electronic service tool to the cab data link connector.
Monitor the fuel position, the rated fuel limit, and the FRC fuel limit.While the vehicle is operating under full load, the parameters should meet the following conditions:
The fuel position is equal to the rated fuel limit.
The fuel position is less than the FRC fuel limit.If the fuel position is equal to the rated fuel limit and the fuel position is less than the FRC fuel limit, the electronics are operating correctly. Proceed to "Vehicle Speed Signal".
If the fuel position is not equal to the rated fuel limit and/or the fuel position is not less than the FRC fuel limit, perform the following tests in order:
When the engine is off, turn the ignition key switch to the ON position. Check the boost pressure on the electronic service tool status screen.When the engine is off, the boost pressure should be 0 kPa (0 psi).Accelerator Pedal Position Sensor
Monitor the status of the accelerator pedal position sensor. Operate the engine at high idle with the vehicle in neutral.If the engine cannot reach the programmed Top Engine Limit, check the duty cycle of the accelerator pedal position sensor in order to ensure that the duty cycle is within calibration (75 to 90 Percent at high idle).If the accelerator pedal position is unstable, check the duty cycle of the accelerator pedal position sensor. Check the duty cycle of the accelerator pedal position sensor by slowly operating the accelerator pedal. Verify that the accelerator pedal position sensor is within calibration. The accelerator pedal position sensor is within calibration when both of the following conditions are met:
10 to 22 percent at low idle
75 to 90 percent at high idleAlso, ensure that the duty cycle changes as the pedal position changes. If a problem with the accelerator pedal position sensor is suspected, refer to Troubleshooting, "Accelerator Pedal (Throttle) Position Sensor Circuit - Test".Vehicle Speed Signal
Monitor the vehicle
