Throttle Position Sensor: Description and Operation

COMPONENT PARTS

VIAS Control Solenoid Valve 1 and 2

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 sends the vacuum signal to the power valve actuator.
