Abstract
A method for operating a camshaft phaser in an internal combustion engine is provided. The camshaft phaser is used to control the phase relationship between a crankshaft and a camshaft of the internal combustion engine. The method includes determining that the internal combustion engine will be placed in an automatic stop mode. The camshaft phaser is then controlled to establish a predetermined phase relationship between the crankshaft and the camshaft. The internal combustion engine is then placed in automatic stop mode and the predetermined phase relationship is maintained by substantially blocking oil flow between the camshaft phaser and the internal combustion engine.
