motor, which is located under the battery tray and
a control cable, which extends from the idle
speed control motor and connects to the idle
lever on the fuel injection pump.
Engine idle speed is controlled by the powertrain
control module, which alters the position of the
motor, and therefore, the position of the idle
lever. To prevent excess slack in the control
cable, the idle speed control motor is fitted with
an idle tracking switch, which prevents further
movement of the motor once the tension on the
control cable is released.
In addition to giving an increased engine idle
speed when the engine is cold, the idle speed
control motor system provides accurate idle
speed control when the engine is warm,
increased idle speed when air conditioning is on
and/or a low battery voltage condition exists and
dashpot engine speed deceleration control.
