The oil control valve is commanded by a pulse-with-modulated signal from the engine control unit. A duty cycle of zero
commands the cam phaser to its default position. A duty cycle of 100% commands the cam phaser to its maximum
phased position. When the phaser must be controlled to an intermediate position, the duty ccle is maintained in the
region of the 'hold position'. This is a medium duty cycle, usually between 35% and 65%, depending on temperature
and voltage conditions.
