General Description
The idle speed is controlled by the Electrical Throttle Control(ETC) System. ETC system is composed of the throttle
motor to operate the throttle valve and the throttle position sensor to detect the opening angle of the throttle valve, the
accelerator pedal position sensor to detect the accelerator pedal position and the one valve type throttle body. The
ECM controls the throttle motor to provide the proper throttle valve opening angle for the target idle speed.
