i had the same code right in front of the gas tank theres a couple of hoses i will bet one has a crack in it i paid 7 dollars from the dealer and it took 2 minutes to do the longest part was jacking the D up so my A$$ would fit under it

 

check the FAQ thread under evap leaks and there is a write up in there, the evap canister hoses are notorious for throwing evap leaks of all sizes

 

I'm going to fix this P0455 thing (hopefully) by replacing the hoses down by the gas tank that go into the EVAP canister. Also I'm going to Autozone and I'm going to get a new purge solenoid. A mechanic I know suggested that and I've read about that. So... I knoe its under the fuse box by the battery but I have no clue about how to replace it and want to do it myself. Any suggestions on how to do it??? It doesnt look like the fuse box will come out easy because all the wires.

 

try the hoses first and clear the code, if it comes back then change the solenoid, my .02 so you dont spend money you dont have to

 

Ya true. I read that Napa Auto Parts has the 2 hoses for $5. They arent made really for Dodge but they look the same. I'll check the sizes of them but I bet they're all the same. Thanks

 

I solved the problem! Theres a small hose that goes into a solenoid or something in the front of the engine compartment on the drivers side. It split and fell off. There was enough hose so that I could cut it and reattach it. Cleared the code and passed inspection.
