vacuum pump assembly drive circuit for cancellation
of vehicle speed.

DESCRIPTION OF OPERATION
The throttle position sensor (with built-in closed
throttle position switch) is used for engine control as
well as cruise control.
The throttle position sensor sends data to the
control unit, regarding the opening of the accelera-
tor. The closed throttle position switch inputs the
data to the control unit on whether or not the
accelerator pedal is operated.
