Air Cleaner Housing: Description and Operation

Intake Air Components:

Purpose and Operation
The air induction system supplies clean air to the throttle body. It operates as follows:

^ Outside air enters from an air intake in the engine air tray through an opening in the front fender apron.

^ in the engine air tray, air is filtered by the air cleaner element.

^ From the engine air tray, the filtered air travels through the mass air flow sensor and air cleaner outlet tube to the throttle body.

^ The positive crankcase ventilation (PCV) system is also supplied clean air through a fitting on the air cleaner outlet tube.

^ Air induction noise is effectively tuned by means of the sealed cover with integral resonator, which is part of the mass air flow sensor.

Components
All engines are equipped with:

^ replaceable dry-type air cleaner element (ACL element).

^ engine air tray attached to the RH front fender apron.

^ mass air flow sensor (MAF sensor).
