Kia Sportage: Engine Control System / Variable Charge Motion Actuator (VCMA) Components and components location
ECM directly controls the actuator and VCM flap for link-structure intake manifold
is operated when motor rotates. This creates air tumble. Motor and position
sensor are mounted inside the actuator in order to receive the position of flap
and send feedback to ECM. They sense current location of flap and determine
whether there is foreign substance or whether system operates in normal condition.
