The valve for variable intake controls the vacuum motor for the damper in the variable intake manifold.

The valve consists of an electro-magnetic valve which controls the air flow between the vacuum tank and the vacuum valve for the damper in the variable intake manifold.

The valve is supplied with voltage from the system relay via fuse and ground (control) internally in the engine control module (ECM). Also see: VARIABLE INTAKE SYSTEM 

The valve for variable intake can be diagnosed by the engine control module (ECM).

The valve for variable intake is on the right-hand side of the engine beside the intake manifold.
