ABSTRACT:
An electronic engine control system has a pressure sensor communicating both to the intake manifold and the ambient air via a valve means selectively introducing either the intake vacuum or the ambient air into the pressure sensor. The control system further includes a valve control means for controlling the operation of the valve means for selectively communicating the pressure sensor to the intake manifold and the ambient air. The valve control means is incorporated in a controller for determining the control value and adapted to produce a control signal to be supplied to the valve means in order to electrically control the valve motion.
