AIV Control Solenoid Valve

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