Altima V6-3.5L (VQ35) (2003)
The power valve is installed in intake manifold collector and used to control the suction passage of the variable induction air control system. It is set in
the fully closed or fully opened position by the power valve actuator operated by the vacuum stored in the surge tank. The vacuum in the surge tank is
controlled by the VIAS control solenoid valve.
VIAS Control Solenoid Valve
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When
the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds
the vacuum signal to the power valve actuator.
