Code P04F0

[SLBronco11]

I am getting a code P04F0. Looks like something to do with the EVAP. Has anyone experienced anything with this code. I brought it to the dealer and they said it was because of my K&N CAI. I got the intake installed last year in November and am just getting the code now. I’m pretty sure the dealer is just saying that.

From what I've seen the K&N intake does cause that code from a couple of YT videos I've watched.

You were right with these video. I took a look at that part and a piece has cracked off just like these guys have experienced. K&N is sending out a replacement part. They said that they might be making a metal piece as this is a known issue.
Thank you again

Should be an easy fix. You may need to reset the code once the new piece is installed.
