A intake manifold tuning solenoid is installed on the intake
manifold plenum. The intake manifold tuning solenoid is an ON/
OFF control type solenoid valve. When current is not passing
through the coil, nipple A is kept air-tight and air passes through
nipple B and the filter. When current is passed through the coil,
air is unable to pass through the filter and it passes through
nipple A and nipple B. ECM changes the ON/OFF of solenoid
valve according to the engine's operating conditions to change
between negative pressure in vacuum tank and atmospheric
pressure and performs the Open/Close of the vacuum actuator.

An engine oil control valve is installed on the cylinder head. The
engine oil control valve is a duty control type solenoid valve and
is used in oil pressure control for cam change. When no current
is passing through the engine oil control valve's coil (duty: 0 %),
port B gets closed and the oil pressure path between port A and
port C connects. Oil that had been acting on the cam change
control piston is expelled from port C via port A. Thus, the low-
speed cam drives the inlet valve. When current is passed
through the coil (duty: 100 %) and the spool moves, port A gets
closed and port B and port C get connected. At this time the oil
pressure-fed from the oil pump passes from port B via port C and
acts on the cam change control piston. Thus, high-speed cam
drives the inlet valve. The ECM changes the duty ratio and
switches the cam in accordance with the engine operation.
