Air Flow Meter/Sensor: Description and Operation
AIR INTAKE SYSTEM DESCRIPTION
The primary function of the air intake system is to provide filtered air to the engine. The system uses a cleaner element mounted in a housing. The
cleaner housing is remotely mounted and uses intake ducts to route the incoming air into the throttle body. The secondary function of the air intake
system is to muffle air induction noise. This is achieved through the use of resonators attached to the air intake ducts. the resonators are tuned to the
specific powertrain. The mass air flow (MAF) sensor is attached to the outlet of the air cleaner housing. The air cleaner life indicator is located on an
intake duct between the air cleaner housing and the throttle plate.
