Description and Operation

Description

The Variable Intake Solenoid (VIS) valve is installed on the intake manifold. The VIS valve controls the vacuum modulator, which actuates the valve in the intake manifold. The ECM opens or closes this valve depending on engine conditions (refer to the table below).

Engine Status VIS Valve Operation
Average Speed Closed Improves engine performance at low engine speeds by reducing intake interference between cylinders.
Low/High Speed Open Minimizes intake resistance by shortening the intake manifold length and increasing the air inlet area.
