Idle Air Control Valve

The idle air control valve has a linear function.

The valve consists of the following components:

^

Inlet (1)

^

Outlet (2)

^

Rotor (3)

^

Permanent magnet (4)

^

Valve (5).

The idle air control valve rotor (3) is equipped with an opening and a closing coil, and with a permanent magnet (4). The engine control module
transmits pulsed ground signals to both coils. Depending on the character of these control signals the rotor drives a valve (5) which controls the air
low to outlet (2).
