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.

Result: A 2880-4 diagnostic code is active with the jumper installed.
Repair: Replace the throttle switch.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Result: A 2880-3 diagnostic code is still active with the jumper installed.
Reconnect the throttle switch and proceed to Test Step 7.
5. Check the Voltage at the Switch Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the throttle switch.
C. Turn the keyswitch to the ON position.
D. Use a suitable multimeter to measure the voltage between the signal terminal and the ground terminal at the switch connector.
E. Turn the keyswitch to the OFF position.
4.9 V to 5.1 V
Result: The voltage is within the expected range.
Repair: Replace the throttle switch.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Result: The voltage is not within the expected range.
Proceed to Test Step 6.
6. Check the Wiring for High Resistance
A. Turn the keyswitch to the OFF position.
B. Disconnect the throttle switch. Disconnect the P1 connector.
C. Use a suitable multimeter to measure the resistance between the following points:
P1:55 to the signal terminal at the switch connector
P1:77 to the ground terminal at the switch connector
Less than 5 Ohms
Result: At least one of the resistance measurements is greater than 5 Ohms.
The fault is in the wiring between the switch connector and the P1 connector.
Repair: Check all wiring between the throttle switch and the ECM. Refer to the Electrical Schematic for the application.
Replace the faulty wiring.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Result: Both resistance measurements are less than 5 Ohms.
Proceed to Test Step 7.
7. Check the Wiring for a Short Circuit
A. Turn the keyswitch to the OFF position.
B. Disconnect the P1 connector from the ECM.
C. Disconnect the throttle switch.
D. Use a suitable multimeter to measure the resistance between the following points:
P1:55 and all other terminals on the P1 connector
