Nissan Maxima Service and Repair Manual: P1800 vias control solenoid valve 1

Nissan Maxima Service and Repair Manual / Engine / Engine control system / DTC/circuit diagnosis / P1800 vias control solenoid valve 1

Description

The VIAS control solenoid valve 1 cuts the intake manifold vacuum signal for power valve 1 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 sends the vacuum signal to the power valve actuator 1.
