Opel

Production Description:

An IAC (idle air control) motor designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or ECM (electronic control module ) receives information from various sensors and will output signals to adjust the IAC motor in or out to adjust engine idle speed by controlling engine idle air. An IAC motor can fail one of two ways, Either the motor short circuits and stops working or the motor will develop high resistance and cause the IAC control motor to react slowly, Either failure can cause the engine to stall at idle.
