A system and method for controlling first and second phase shiftable camshafts in a variable cam timing engine is provided. The method includes determining when the first camshaft is moving toward a first scheduled phase angle with respect to the crankshaft at a faster rate than the second camshaft is moving toward the first scheduled phase angle. Finally, the method includes slowing down the first camshaft so that the rate of movement of the first camshaft approaches a rate or movement of the second camshaft toward the first scheduled phase angle.
