I have a 98 Nissan Pathfinder.  My charcoal canister let loose and I followed steps to replace canister and valve that sits on the canister. Also blew the entire system out.  Lots of charcoal.  After this I passed inspection and drove a month or more and I the  1447 returned.  I couldn’t figure it out and sadly took to a shop. They said my lines were gummed with charcoal! They thought I did a poor job of cleaning and replaced  the valve in the engine compartment and vacuumed. When I picked it up it threw the 405 code.  I replaced canister and attached valve AGAIN.  I figured I bought one that was bad.   This did nothing except lighten my wallet.  I’ve searched quite a bit and not found much regarding 405  for pathfinders. Google AI stated EGR valve is the culprit.  Before getting into this, I wanted to see if anyone had some thoughts as to the 405 code. Not sure I trust AI enough for this. Thanks for any tips.
