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




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 idle air control (IAC) valve is heated by engine coolant from the cylinder head.
