Idle Speed Control
x Controls the throttle valve opening angle so that it is close to the target idle speed calculated by the PCM.
x The PCM calculates the target throttle opening angle by adding each type of correction to the basic duty value
which is the basis of the throttle valve opening angle, and then sends a duty signal to the throttle valve actuator.
The basic duty value is determined by the target engine speed.
x Each type of correction is as follows.
