P0406 code help!
 

Hello, about 3-4 weeks ago my jeep gave a check engine light and code p0404. After research I replaced the egr valve. Now, after driving for three or so weeks i have a new check engine light code p0406 which is related to the egr valve again that I just replaced. Looking for thoughts or ideas on what to do next. Thanks!

I would read some older posts on the forum. There is a lot of good history here. There are many threads that start out the same way as yours with many recommendations. Good luck.
