In a VCT system, a method uses a controller to automatically determine a state of a phaser based on an identifier. The identifier identifies a filtered signal of the crank shaft and cam shaft and uses the same to identify the phaser state. A reset signal is generated by the identifier to reset the VCT system, specifically to reset a control law whereby the unnecessary information retained by the VCT system is cleared. Therefore, the controller is able to promptly and accurately determine the phaser position and state.
