Throttle Body Assembly

Throttle body assembly controls airflow to engine through butterfly valve. Throttle position is controlled by either linkage or cable/cam mechanism. Body is one-piece aluminum casting with single bore and air by-pass channel.

Air by-pass channel carries idle airflow which is regulated by air by-pass valve. Air by-pass valve is controlled by ECA to adjust both cold and warm idle speeds. Air by-pass valve uses solenoid valve to vary volume of idle airflow allowed to enter by-pass channel.
