The rotary solenoid type IAC valve is located in front of the intake air chamber and intake air bypassing the throttle valve is directed to the IAC valve through a passage. In this way, the intake air volume bypassing the throttle valve is regulated, controlling the engine speed. The ECM operates only the IAC valve to perform idle–up and provide feedback for the target idling speed.

The lambda control and the idle speed emissions level must not be tested when the engine is very hot, e.g. immediately after driving sharply or after measuring engine output on the dynamometer.
Testing, adjusting
1 Complete measurement sheet.
2 Switch off air conditioning or automatic climate control. Move selector lever into position "P".
3 Read out DTC memory. Note: Not available on model year 1984-1986.
