A control module may include a cam phaser control module, a cam phaser oil pressure determination module, and a system oil pressure prediction module. The cam phaser control module may control an oil control valve (OCV) to control an oil flow to a cam phaser. The cam phaser oil pressure determination module may be in communication with the cam phaser control module and may determine a first engine oil pressure at a location between the OCV and the cam phaser when the OCV is in a open position. The system oil pressure prediction module may determine a second engine oil pressure at a location between the OCV and an oil pump outlet based on the first engine oil pressure.
