How does the idle speed control actuator work?
In a vacuum operated setting, the actuator opens the throttle slightly to increase air/fuel flow. An idle speed control actuator is controlled by an idle speed control actuator solenoid. This solenoid is controlled by a control module.
How does the throttle kick actuator work on a car?
In order to decrease idle speed, this solenoid is turned on, routing vacuum to the idle speed control actuator, allowing the throttle to fully close. Like most mechanical parts built on vehicles these days, the throttle kick actuator is designed to last the entire lifespan of a vehicle.
When do I switch to idle speed control?
The control mode selection logic switches to idle speed control when the throttle angle reaches its zero (completely closed) position as detected by a switch on the throttle that is closed and engine RPM falls below a minimum value. This condition often occurs when the vehicle is stationary.
How can I tell if my idle control motor is working?
Look for a difference in idle speed. Allow the engine to run for a minute so it settles to a consistent idle, then take note of any difference in the idle RPMs versus the idle you observed earlier. If the idle has not changed at all, it’s likely because your idle control motor has not been functioning.

Who is the inventor of idle speed control?
A highly simplified two-input (idle bypass valve opening and spark advance), two-output (engine speed and intake manifold pressure) idle speed control model for IC engines was developed by Yurkovich and Simpson (1997) and used in this work.
What happens when the idle control valve fails?
When the idle control valve fails it can cause all sorts of issues with the vehicle, and in some cases may even render it undrivable. Usually a bad or failing idle control valve will produce a few symptoms that can alert the driver of a potential issue. 1. Irregular idle speed
