WASHER-THRUST 2663987 - Caterpillar

Probable Causes
The probable root causes are listed in order below:
Poor electrical connections
"Engine Monitoring"
Battery power or ground to the ECM
Air inlet system (boost)
Accelerator pedal position sensor
Fuel supply
Vehicle speed circuit
Powertrain control
Torque limit switchRecommended Actions
Perform the following diagnostic procedures in order:
Check the vehicle harness and the connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
Check the parameters for "Engine Monitoring".
Connect an electronic service tool.
Check for diagnostic codes that are capable of derating 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)
100-11 Very Low Oil Pressure (46)
Check the 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 (J5/P5)
Engine speed/timing sensor (J9/P9)
Use an electronic service tool to check for a 168-02 ECM Battery Power Intermittent. 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".
Check for an electronic system problem.
Connect an electronic service tool.
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. Go to Step 6.
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:
Connect an electronic service tool.
When the engine is OFF, turn the Ignition Key Switch to the ON position. Check the boost pressure on an electronic service tool status screen.When the engine is OFF, the boost pressure should be 0 kPa (0 psi).
Monitor the status of the accelerator pedal position sensor. Operate the engine at high idle with the vehicle in neutral.If the engine can not reach the programmed "Top Engine Limit", check the Accelerator Pedal Position Duty Cycle in order to ensure that the Accelerator Pedal Position Duty Cycle is within calibration (75 to 90 Percent at high idle).If the accelerator pedal position is unstable, check the Accelerator Pedal Position Duty Cycle. Check the Accelerator Pedal Position Duty Cycle by slowly operating the accelerator pedal in order to 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".Note: If the engine exceeds the top engine limit, the "Top Engine Limit with Droop" is programmed
