Intake Air System

Intake Air System

Intake Air System Diagram




This system supplies air for engine needs. A resonator in the intake air pipe provides additional silencing as air is drawn into the system.

Intake Air Bypass Control Thermal Valve




When the engine is running, the intake air bypass control thermal valve sends air to the injector.

Intake Manifold Runner Control (IMRC) Valve Position Sensor (K20A3 engine)




The IMRC position sensor is a potentiometer connected to the IMRC valve shaft. As the 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.
