Abstract: A vehicle system includes a vehicle engine, a plurality of intake and exhaust valves coupled to the vehicle engine configured to adjust performance of the vehicle engine, and a camshaft coupled to the plurality of intake and exhaust valves and configured to control timing of the intake and exhaust valves. The vehicle system also includes a camshaft phaser configured to adjust the position of an engine's camshaft. Moreover, the vehicle system includes a vehicle processor. The vehicle processor is configured to store data including vehicle data, and apply increased oil pressure to the camshaft phaser based on vehicle data such that oil pressure is increased at a predetermined vehicle data range of camshaft phaser instability to prevent future camshaft position instability.
