Throttle Full Open Switch: Description and Operation
Fig. 2 Engine Compartment Locations
The throttle valve switch is attached to the throttle chamber, and actuates in response to accelerator pedal movement. This switch has two sets of contact
points. One set monitors the idle position and the other set monitors full throttle position. The idle contacts close when the throttle valve is positioned at
idle and open when at any other throttle position. The full throttle contacts close only when the throttle valve is positioned at full throttle or more than 34
degree opening of the throttle valve. The contacts are open when the throttle valve is at any other position. The idle switch compensates for enrichment
during idle and after idle, and sends fuel cut signal. The full throttle switch compensates for enrichment in full throttle.
