IDLE SPEED CONTROL VALVE

Function

The idle control valve is located in a tube bypassing the throttle. The control unit controls this
device to ensure stable idling in all operating conditions.

Specifications

resistance coil(s):

± 20 ohms

supply voltage:

12 Volts

A rotary slide valve attached to the armature is turned to open the air bypass until the
desired idle speed is obtained. The position of the armature is controlled by the force of
an internal spring opposing the force of a solenoid (types with to terminals) or controlled
by two solenoids energised alternately which exerts opposing forces on the armature
(types with three terminals).

Electrical control

Types with two terminals

As a current flows through the coil the armature
is turned against the spring force. As the current
increases the airflow and the idle speed increases.
If the current through the coil is switched off due
to a mall functioning system, the valve is forced
into a position which results in a (too) high idle
speed.

The idle control valve has a connector with two
terminals. On one of those terminals is connected
to the battery voltage. This supply-voltage is
often switched with a relay. The other terminal
leads directly to the control unit. The current
through the coil is switched on during the time the
control unit connects this terminal to ground. The
voltage on this terminal is during this time 0
Volts. During the time the current through the coil
is switched off, the voltage on this terminal is 12
Volts.
