07 ram, 5.7 hemi. Changed my plugs over the weekend, truck is now throwing a p0452 code. It was a couple of days later, the code was thrown. The information I was able to get says... "evaporator pressure switch stuck closed". I don't know if the 2 are related, or just a coincidence. My gut tells me it has to do with the vapor canister near the tank. There has been a build up of mud, underside of my truck. The canister is new, however. Any guidance from you pro's would be much appreciated! Thanks!

 

Here is all the info on P0452 from Mitchell OnDemand. I would check all those hoses that go into and from the evap can though.

This link is only good for 7 days
