Typical example of the pin locations on connector P1 (33) Sensor return (43) Sensor supply (+8 Volts DC) (53) Sensor inputTest Step 1. Inspect Electrical Connectors and Wiring
Inspect the P1/J1 connector, OEM harness and the connectors on the harness. Thoroughly inspect the digital throttle position sensor connector. 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 digital throttle position sensor:
P1:33
P1:43
P1:53
Check the screw for the ECM connector for the correct torque of 5.0 N m (44 lb in).
Check the harness for abrasion and pinch points from the digital throttle position sensor to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness is free of corrosion, of abrasion or of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following repair:Repair the connectors or the harness and/or replace the connectors or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are completely coupled.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position.
Monitor the active diagnostic code screen on the electronic service tool. 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
