Air Intake System

The main components of the air intake system are air cleaner, mass air flow sensor, air cleaner, intake air pipe,
throttle body, intake collector, idle air control valve and intake manifold.
The air (by the amount corresponding to the throttle valve opening and engine speed) is filtered by the air
cleaner, passes through the throttle body, is distributed by the intake manifold and finally drawn into each com-
bustion chamber.
When the idle air control valve is opened according to the signal from ECM (PCM), the air bypasses the throttle
valve through bypass passage and is finally drawn into the intake manifold.
