Description

Variable Intake Solenoid (VIS) valves are installed on the intake manifold (VIS valve 1) and the surge tank (VIS valve 2). VIS valves 1 and 2 control vacuum modulators, which actuate the valves in the intake manifold and surge tank. These valves are opened or closed by the ECM depending on engine conditions (see the table below).
