Variable Swirl Control actuator
Variable swirl control actuator consists of DC motor and motor position sensor(potentiometer) which detects the position
However, because air flow rate is too high, swirl effect is neglectable thus, swirl valve is opened for efficient intake of air.
To prevent swirl valve and shaft form being stuck by foreign metarial, and to learn max opening and closing position of
Variable swirl control actuator
P2009 is set when open or short to ground in variable swirl actuator driving motor (+) output terminal. The polarity of (+)
