Abstract
An engine control system in a vehicle including a variable displacement internal combustion engine, an intake manifold coupled to the variable displacement internal combustion engine, a controller for controlling the displacement of the variable displacement internal combustion engine, a pressure sensor sensing manifold pressure, the pressure sensor electronically coupled to the controller, and where the controller receives pressure information from the pressure sensor and changes the displacement of the variable displacement internal combustion engine in response to the pressure information.
