Intake Air System

Intake Air System

Refer to the System Diagram to see the functional layout of the system.




Intake Air Bypass Control Thermal Valve
When the engine is running during warm up, the intake air bypass control thermal valve sends air to the injector.




Intake Manifold Tuning (IMT) (Intake Manifold Runner Control (IMRC)) Valve Position Sensor (K20A3 engine)
The IMT (IMRC) position sensor is a potentiometer connected to the IMT (IMRC) valve shaft. As the IMT (IMRC) valve position changes, the sensor varies the signal voltage to the ECM/PCM.




Throttle Body
The throttle body is a single-barrel side draft type. The lower portion of the IAC valve is heated by engine coolant from the cylinder head.
