Wide Open Throttle (Wot) Switch
The WOT switch is mounted on the side of the throttle body. The switch provides a voltage signal to the ECU under wide open throttle conditions. The ECU responds to this signal by increasing the amount of fuel delivered by the injector.
NOTE:
If WOT switch is closed (throttle wide open) during engine cranking, fuel injector will be deactivated by ECU to clear flooded engine.
