Throttle Switch
A contact type throttle switch is installed on the throttle chamber of all models. It converts throttle position into electrical signals to inform ECU of throttle position. Signals are sent to ECU when throttle is fully open or at idle. See Fig 1 . The potentiometer prevents loss of power during sudden acceleration/deceleration by signaling the ECU of necessary fuel enrichment requirements.
NOTE:
Models with automatic transmissions are also equipped with a dashpot to prevent abrupt closing of throttle valve.
