P1800 VIAS CONTROL SOLENOID VALVE 1

Description

INFOID:0000000003388184

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 vac-
uum signal to the power valve actuator 1.

P2101 ELECTRIC THROTTLE CONTROL FUNCTION

Description

INFOID:0000000003388199

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor. The throttle position
sensor provides feedback to the ECM, when opens/closes the throttle valve in response to driving conditions
via the throttle control motor.
