Abstract
An apparatus () and method for controlling an angular position of a camshaft () in an internal combustion engine having a camshaft phaser () for controllably varying the phase relationship between a crankshaft of the internal combustion engine and the camshaft (). The camshaft phaser () can be actuated by an electric motor () having an actuator shaft () operating through a gear reduction drive train () having a stationary adjusting member () which rotates when a phase change adjustment is desired. A sensor () can generate a signal corresponding to an angular position of the stationary adjusting member () of the gear reduction drive train (). An engine control unit () can adjust a position of the camshaft () through operation of the electric motor () for rotating the stationary adjusting member () based on the generated signal corresponding to the angular position of the stationary adjusting member ().
