when the TPS indicates closed throttle the ICV opens bypassing the butterfly on the throttle to let a small amount of air into the engine to keep it at idle, once the throttle is opened it closes, its a plunger that blocks a bypass of the butterfly in the throttle body, it simply a motor that pushes the plunger forward and backwards opening and closing this air way

how it governed how is it operated,

does it idle by air pressure/suction ??

is it activated by the pressure/suction or is it activated once the engine reaches its running temp

does it act along with the water temp sensor to tell the ecu to determine the idle speed ?

i want to know how this this is operated ??
