an actuator control system including a servo - actuator comprising : at least one coil ; a solenoid core within the at least one coil ; a rod within the solenoid core having a first end , a second end , and a length extending between the first end and the second end , the first end coupled to a sensing core pin having a profile ; a moveable member coupled to the second end of the rod ; a moveable armature within the solenoid core surrounding a portion of the length of the rod and biased by a spring ; and a noncontact sensor integral with servo - actuator and aligned with the first end of the rod coupled to the sensing core pin . a selected position of the servo - valve actuator may be set by the ecu by sensing the position of the sensing core pin using the non - contact sensor .
