(P1-68) Input #8 (remote accelerator position sensor) Test Step 1. Inspect the Electrical Connectors and the Wiring
Connect Cat ET to the data link connector. Turn the ignition key switch to the ON position. Verify that the parameter for the PTO configuration is programmed to the "Remote Throttle".
Turn the ignition key switch to the OFF position.
Thoroughly inspect ECM vehicle harness connector J1/P1, the firewall bulkhead connector and the connector for the remote accelerator position sensor. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the remote accelerator position sensor.
Check the allen head screw on each ECM connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and wiring for abrasion and pinch points from the remote accelerator 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 - Proceed to Test Step 2.
Not OK - Repair: Perform the following diagnostic procedure:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
Ensure that Cat ET is connected to the data link connector.
Turn the ignition key switch to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check and record active diagnostic codes. Note: When the ECM automatically calibrates new duty cycle values for the low idle throttle position and the high idle throttle position, the ECM assumes 22 percent duty cycle at low idle and 75 percent duty cycle at high idle. As a result, you may notice that the status of the throttle position reaches 100 percent well before the remote accelerator position sensor is fully actuated. This is normal. After cycling the accelerator pedal to the high idle position, the ECM will adjust the calibration automatically. The ECM will adjust the calibration automatically provided that the high idle stop position is within the 75 to 90 percent duty cycle range, and the low idle is in the 10 to 22 percent duty cycle range. During normal operation, you may notice that more movement of the remote accelerator position sensor is required for the status of the throttle position to increase above three percent. You may also observe that the status reaches the 100 percent value prior to the limit of the high idle position. This is done in order to ensure that the accelerator reaches these two critical points for engine operation.Expected Result:Result 1 30-08 or 30-13 are active.Result 2 There are no active diagnostic codes that are related to the remote accelerator position sensor at this time, but a problem is suspected.Results:
Result 1 - 30-08 or 30-13 are active. Proceed to Test Step 3.
Result 2 - There are no active diagnostic codes at this time. Proceed to Test Step 3.Test Step 3. Check the Supply Voltage for the Remote Accelerator Position Sensor
Verify that the ignition key switch is in the ON position.
Measure the voltage between terminal "A" (+12 V) and terminal "B" (sensor common) at J406 remote accelerator position sensorconnector. Expected Result:The measured voltage is between 11.0 VDC and 13.5 VDC.Results:
OK - The voltage is OK. Proceed to Test Step 4.
Not OK - The vehicle wiring or the battery is causing the problem. Repair the wiring or the battery. Replace the wiring or the battery. Perform the repair that is necessary. Verify that the repair has fixed the problem.STOPTest Step 4. Check the Duty Cycle of the Remote Accelerator Pedal Position Sensor
Verify that the ignition key switch is in the ON position.
Monitor the duty cycle of the PTO throttle sensor on Cat ET. Access the following display screen in order:
"Service"
"Calibrations"
"Monitor Throttle Position Sensor"Expected Result:The duty cycle is between 10 and 22 percent with the accelerator pedal assembly in the low idle position, and the duty cycle is between 75 and 90 percent with the accelerator pedal assembly in the high idle position.Results:
OK - The remote accelerator position sensor is operating correctly. Proceed to Test Step 5.
Not OK - The remote accelerator position sensor is not operating correctly. Proceed to Test Step 6.Test Step 5. Check the Status of the Power Train Data Link on Cat ET
Start the engine. While the status of the "PTO Throttle Position" is being monitored on Cat ET, actuate the remote throttle. The throttle position status and the engine should respond to the change in the throttle position.
Go to the "System Troubleshooting Settings" section of Cat ET and turn off the power train data link.
While the status of the "PTO Throttle Position" is being monitored on Cat ET, actuate the remote throttle. Also, actuate the remote throttle while the engine response is being monitored. Expected Result:The status of the "PTO Throttle Position" and the engine should respond to the change in the position of the remote throttle position sensor.Resul
