Take off the hose and spray WD-40 in it, then use compressed air to blow it all the way in. This method usually works as a temporary repair if you don't drive your car much. If you drive it a lot, then you may not need to replace the valve after using the WD-40 at all. There have been repair posts on the forum about this for a long time.

i would think its just a one way valve whats the big deal i tryed the blowing techniqe with my mouth it seemed not to be stuck air flows fine. if you suck nothing its closed thats the way it should be hmmmm

I had the 1416 code and found that I had a loose exhaust clamp on the x-pipe that was installed a couple years ago. I believe this allowed some outside air to affect the O2 sensor until the exhaust pipe warmed up enough to expand the pipe and seal the leak.
After tightening the clamp a few weeks ago I have not had this code.
