Intake Manifold Runner Control Valve: Notes
Intake manifold runner control valve is consist of intake manifold runner control valve to open/close the right/left half section installed at each port of intake manifold runner control valve motor to drive open/close the valve.
ECM transmits the open/close signal to intake manifold runner control valve motor according to the driving condition based on the signals of engine speed, coolant temperature etc. ECM stabilizes combustion by causing strong swirl flow (revolving flow) by closing the intake manifold runner control valve.
