The Multiport Fuel Injection System consists of control (IAC) motor according to engine coolant
sensors, actuators and the engine control module temperature, A/C, and other electrical load. Thus,
(ECM) or powertrain control module (PCM) idle speed is kept at an optimum speed. In addition,
. The sensors detect the engine condition. The when the air conditioning switch is turned off and on
module controls the system based on signals from while the engine is idling, the IAC motor adjusts the
these sensors. The actuators work under the control throttle valve bypass air amount. Thus, idle speed is
