AIV Control Solenoid Valve
The AIV control solenoid valve cuts intake manifold vacuum signal for AIV control. The solenoid valve actuates in response to the ON/OFF signal from the ECCS control unit. When the solenoid is off, the vacuum signal from the intake manifold is cut. As the control unit outputs an ON signal, the coil pulls the plunger downward, and feeds the vacuum signal to the AIV control valve.
