2.5.2.3. Regulator of idling (IAC)

The regulator of idling of Mazda S (GG) is in essence transferred from the modern MPV (LW) model with the FS engine except for the following:
use of coefficient of MAP at correction on feedback;
target frequency of rotation of the engine differs for the purpose of coordination with characteristics of the vehicle.
