Air Intake Control System: Description

The air intake control system supplies air for all engine needs. The system consists of the air cleaner, air intake pipe, throttle body, Electronic Idle Control Valve (EICV), throttle angle sensor, fast idle mechanism and intake manifold.

On Legend Coupe with 2.7L engine, a by-pass control system is incorporated into the intake system. Two air paths are provided in the intake manifold to allow selection of the intake path length to vary for different engine operations. A long path is used for high torque at low RPM. A shorter path is used for high power at high RPM.
