Kia Sedona: Variable Intake Solenoid (VIS) Valve Description and Operation
Third generation YP (2014-2025) / Kia Sedona YP Service Manual / Engine Control / Fuel System / Engine Control System / Variable Intake Solenoid (VIS) Valve Description and Operation
| Description |
Variable Intake manifold 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 that activate valves in the
intake manifold and the surge tank. These valves are opened or closed
by ECM according to engine condition (Refer to below table).
| Engine condition | VIS valve 1 | VIS valve 2 | Operation |
| Intake Manifold | Surge Tank | ||
| Low speed | Closed | Closed | Increasing engine performance in low engine speed by reducing intake interference among cylinders |
| Medium speed | Open or Closed | Open | Increasing intake efficiency |
| High speed | Open | Open | Minimizing intake resistance by shortening intake manifold length and increasing area of air entrance |
