When one's foot is off accelerator throttle cuts off intake air to engine. IAC valve bypasses throttle and provides sufficient air to maintain idle. Valve receives varying signal from PCM, to try and maintain spec idle rpms, depending on various engine sensor inputs.



Thanks for the thorough explaination. I appreciate your pointing out the terminology section. I have been in the FAQ's many times and blatantly looked over it. There is just so much information available it can be overwhelming.

I once belonged to a Paid club for my Lincoln LS and got very out of my membership and am amazed at how much can be found here for free. You folks are without a doubt the most helpful I have had the pleasure of conversing with.
