Schematic for the accelerator pedal position sensor
Test Step 1. Monitor the Status for the "Accelerator Pedal Position"
Turn the keyswitch to the OFF position.
Connect Cat ET to the service tool connector.
Turn the keyswitch to the ON position.
Access the status for the "Accelerator Pedal Position".
While the status is monitored, depress the accelerator pedal and release the accelerator pedal. The correct status for the "Accelerator Pedal Position" is 100 percent when the accelerator is fully depressed. The correct status for the "Accelerator Pedal Position" is less than 5 percent when the accelerator is fully released.
Turn the keyswitch to the OFF position. Expected Result:The correct status for the "Accelerator Pedal Position" is being reported by Cat ET.Results:
OK - The correct status for the "Accelerator Pedal Position" is being reported by Cat ET.Repair: The accelerator pedal position sensor is operating correctly. There may be an intermittent electrical problem in the circuit for the accelerator pedal position sensor. If an intermittent problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect".Verify that the engine is not in PTO mode. PTO mode may cause the accelerator pedal position sensor to be ignored.Verify that all required parameters are programmed. Certain unprogrammed parameters may cause the engine to be limited to low idle. Refer to Troubleshooting, "System Configuration Parameters".If a diagnostic code that is related to the accelerator pedal position sensor is still active, proceed to Test Step 2.
Not OK - The correct status for the "Accelerator Pedal Position" is not being reported by Cat ET. The accelerator pedal position sensor is not operating correctly. Proceed to Test Step 2.Test Step 2. Monitor the Duty Cycle
Turn the keyswitch to the ON position.
Access the following display screen in order:
"Service"
"Calibrations"
"Monitor Throttle Position Sensor"
While the duty cycle is being monitored, depress the accelerator pedal and release the accelerator pedal. The correct duty cycle is 10 percent to 22 percent when the accelerator pedal is released. The correct duty cycle is 75 percent to 90 percent when the accelerator pedal is depressed.
Turn the keyswitch to the OFF position. Expected Result:Cat ET reports that the duty cycle is correct.Results:
OK - Cat ET is reporting the correct duty cycle for the sensor.Repair: The duty cycle is within the specified range. There may be an intermittent electrical problem in the circuit for the accelerator pedal position sensor. If an intermittent problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect".Verify that the engine is not in PTO mode. PTO mode may cause the accelerator pedal position sensor to be ignored.Verify that all required parameters are programmed. Certain unprogrammed parameters may cause the engine to be limited to low idle. Refer to Troubleshooting, "System Configuration Parameters".STOP
Not OK - Cat ET is not reporting the correct duty cycle for the sensor. The duty cycle is not within the range. Proceed to Test Step 3.Test Step 3. Inspect the Electrical Connectors and the Wiring

Location of the J1/P1 ECM connectors (typical left side engine view)
Thoroughly inspect the J1/P1 ECM connector, the firewall bulkhead connector and the accelerator pedal position sensor connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.

Sensor connector
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the accelerator pedal position sensor.
Check the allen head screw for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and wiring for abrasion and pinch points from the accelerator pedal position sensor to the ECM. Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - The harness and
