Throttle Opener Control
When the A/C switch or instrument panel light and power steering switch are ON, the engine
idle speed is increased by the changing of throttle blade opening. The ECU de-energizes the solenoid valve which supplies manifold vacuum to the throttle opener at or above a predetermined engine speed and throttle opener operation is suspended.
