Throttle Full Open Switch: Testing and Inspection

1. Disconnect switch electrical connector.
2. Using a suitable digital volt-ohmmeter, measure resistance while rotating switch from closed to wide open throttle position.
3. Resistance should be infinite at closed throttle, while low resistance should be obtained at wide open throttle. If operation is not as specified, replace switch.
