Default code 1416

Little help please,,,i am getting code 1416 ,, dealer said this was emissions related " stuck emissions valve " . the check engine lite comes on now and then . i reset the code and all is fine. . my question is ,,,,, if the code has been reset and the check engine lite is off will i pass emissions. dealer wants 500 to remove intake. cant afford that right now. car runs fine. is it true if there is no check engine lite on it will pass?

Here is a thread with a DIY, won't cost you an arm and a leg to fix and it's simple.

Been there done that. Tried the WD40 trick. Worked for a little while. I ended up replacing the check valve with a new one. It's behind the intake manifold so it takes a little bit of work.
