DESCRIPTION AND OPERATION

Intake Air System

NOTE: All engines are equipped with a replaceable

dry-type air cleaner element (ACL element)(960 1 ).
The air induction system performs the following

functions:

•

Supplies clean air to the throttle body (9E926).

•

Allows outside air to enter from an engine intake air

resonator (9F763)-3.8L engine, or engine intake

air tube-4.6L (2V) engine, through an opening in

the front fender apron ( 16054) to the engine air

cleaner (ACL)(9600).

•

Filters air in the engine air cleaner by means of the

air cleaner element.

Air Cleaner Element

The air cleaner element (ACL elementX960 1) is:

•

a dry-type filtering element.

•

chemically-treated, pleated paper air filtering

element which permits air flow through the air

induction system, filtering out unwanted dust, dirt

and debris.

DIAGNOSIS AND TESTING

Intake Air System

Refer to the Powertrain Control

•

From the engine air cleaner, the filtered air travels

through the mass air flow sensor (MAF

sensor)( 1 28579) and air cleaner outlet tube

(98659) to the throttle body.

•

Supplies clean air to the positive crankcase

ventilation

(PCV)

system through a fitting on the air

cleaner outlet tube.

•

On 3.8L engines, eliminates air induction noise by

means of the sealed and tuned engine intake air

resonator.
