P0506
Idle speed control speed less
than the target idle speed
Throttle actuator control motor from is controlled by
engine control module (ECM). DC motor in the throt-
tle body drives the throttle. In order to reduce the
idle speed and change the spark and fuel supply,
engine control module instruct the throttle to close,
thereby reducing the air flow that will access to the
engine, so the idle is reduced. In order to increase
idle speed, the engine control module to insteuct the
throttle to open, so that more air could go through
the throttle.
Engine control module (ECM) conduct the calcula-
tion and control to engine target idling based on
coolant temperature, speed compensation, slow
adjustment, AC compensation, voltage compensa-
tion.
