Zusammenfassung:	A control system for a vehicle includes a motor driver module, a correlation triggering module, a target phase angle module, and a correlation control module. The motor driver module controls an electric camshaft phaser of an engine based on a desired phase angle between a position of a crankshaft and a position of a camshaft. The correlation triggering module selectively generates a signal based on the position of the camshaft. The target phase angle module adjusts the desired phase angle to a predetermined phase angle in response to the generation of the signal. The correlation control module, in response to the generation of the signal: determines the position of the crankshaft when the camshaft is in a predetermined position; and selectively outputs a fault indicator based on a comparison of the position of the crankshaft and a predetermined crankshaft position range corresponding to the predetermined position.
