Air Induction (Intake) System

The air induction system supplies filtered air to the engine to mix with the fuel. It consists of an air cleaner assembly, vane air flow meter, throttle body, intake plenum and an air bypass valve. The vane air flow meter is located in the air filter housing and measures the amount of air flow and ambient air temperature, then sends a corresponding signal to the ECA. The throttle body controls intake air quantities and consists of an aluminum housing, throttle valve, throttle position sensor and a dash pot. An idle air bypass system supplies small quantities of metered air during engine idle. The throttle position sensor is mounted on the left side of the throttle body.
