Abstract
A control system for an engine includes a position determination module and a position control module. The position determination module determines a first cam phaser position for starting the engine prior to engine shut down, and determines a second cam phaser position for starting the engine while the engine is shut down. The position control module adjusts a cam phaser to the first cam phaser position at engine shut down. The position control module adjusts the cam phaser from the first cam phaser position to the second cam phaser at engine start up when a difference between the first cam phaser position and the second cam phaser position is greater than a predetermined difference. A method for controlling an engine is also provided.
