Information:
The throttle switch uses resistors to modify the voltage signal from the ECM. The resistance of the switch changes dependent on which position the switch is in. The ECM uses the signal voltage to determine which mode has been selected.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Thoroughly inspect the terminal connections on the P1/J1 connector.
B. Thoroughly inspect the connector for the throttle switch.
C. Refer to Troubleshooting, "Electrical Connectors - Inspect".
D. Perform a 30 N (6.7 lb) pull test on each of the wires in the connectors that are associated with the throttle switch.
E. Check the harness for abrasions and for pinch points from the switch back to the ECM.
Damaged wire or connector
Result: A damaged wire or damaged connector was not found.
Proceed to Test Step 2.
Result: A damaged wire or damaged connector was found.
Repair: Repair the damaged wire or the damaged connector.
Use the electronic service tool to clear all logged diagnostic codes. Verify that the repair eliminates the fault.
2. Check for Active or Recently Logged Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position. Do not start the engine.
D. Check for active diagnostic codes with the throttle switch in each position. Wait at least 10 seconds with the switch in each position for activation of the diagnostic codes.
