The scanner (P0410) and troubleshooting told me it was this valve. I removed it and found it to be seized up. A little twisting back & forth, and lots of carb cleaner and it moves freely again. (Verified by applying power to the connector and watching the valve open and close.) I read that it will now take 3 cycles for the check engine light (or whatever it's called) to go off. What exactly is 3 cycles?
