If you need a new unit, I would google southern state salvage yards
like Texas, Florida, Nevada. You send them an email or call them.
They will let you know if the part is available, plus shipping to your
address. Here is some info on how it works.
The air induction system is designed to send secondary air to the
exhaust manifold, utilizing a vacuum caused by exhaust pulsation in
the exhaust manifold. The exhaust pressure in the exhaust manifold
usually pulsates in response to the opening and closing of the exhaust
valve and it decreases below atmospheric pressure periodically. If a
secondary air intake pipe is opened to the atmosphere under vacuum
conditions, secondary air can be drawn into the exhaust manifold in
proportion to the vacuum.
On some applications, the Air Induction Valve (AIV) control solenoid
and the Swirl Control Valve (SCV) solenoid cuts the intake manifold
vacuum signal. These solenoids have an electrical connection and
vacuum lines. If equipped in your vehicle, make sure the unit is
properly mounted and all connections are properly installed.
The introduction of fresh air (oxygen) into the exhaust stream allows a
further burning of the exhaust gases even after they have left the
combustion chamber. In this way, the air induction system contributes
to the reduction of CO and HC emissions in the exhaust gasses. The
system usually consists of two air induction valves, filter hoses and
routing cables.
Air Induction Valve Case
The air induction valve case is attached to the air cleaner, and
consists of 2 reed valves, a rubber seal and a filter.
There are 2 types of air induction valve cases. One type is equipped
with 2 hose connectors, and is installed on California models. The
other type is equipped with 1 connector and is installed on non-
California models.
Air Induction Valve
Two reed type check valves are installed in the air cleaner. When the
exhaust pressure is below atmospheric pressure (negative vacuum),
secondary air is sent to the exhaust manifold.
When the exhaust pressure is above atmospheric pressure, the reed
valves prevent secondary air from being sent back to the air cleaner.
Air Induction Valve Filter
The air induction valve filter is installed at the dust side of the air
cleaner. It purifies secondary air to be sent to the exhaust manifold.
Air Induction Pipe
The secondary air fed from the air induction valve goes through the
routing pipe to the exhaust manifold.
Anti-Backfire (AB) Valve
The AB valve provides air from the air cleaner to the intake manifold
to prevent backfiring during deceleration.
