A very newBie question :

How do i clean the Air clontrol Valve for Nissan Sentra GXE ' 95
I am not sure as to where it is located !!

Can anyone share pictures or pointers !

I want to try the clean it and see whether it helps before replacing it as suggested by the mechanic. (The check engine light is on and the error code given to to replace IACV)
