Subaru Air Control Valve

[research_stuff]

I am trying to find where the Air Control Value is located on a 1991
Legacy.

I have not been able to find a picture or an explaination where the Air
Control valve is located so I can troubleshoot the valve.

Does anyone know where it is?




Thanks in Advance

Not sure myself but on a 91 XT6 it is bolted to the intake manifold just to
the left of the throttle body. Look at the air cleaner housing and the air
intake tube. Looking for a hose about 1" in diameter. This hose will lead
you to the air control valve. This valve picks up air somewhere between
the air filter and throttle body. Air then enters the intake manifold
somewhere downstream of the throttle body.
