DESCRIPTION
The intake air volume at idle is controlled by opening or closing the idle speed control valve provided in the air path that bypasses the throttle valve.
If there is a malfunction of the ISC system, the actual engine speed will not be identical to the target engine speed.
The engine control module checks the difference between the actual engine speed and the target engine speed.
