Hey everyone! I wanted to get some advice from the forum on my code that refuses to go away. I have a p0440 code that after replacing my gas cap, purge valve (Which is what the code refers to, the "canister purge valve"), the j hose.I also checked all the lines going from the gas tank to the purge valve all seem to be good. Anyone have any more ideas? I replaced the purge valve around 6 months ago. Unless there is another purge valve I'm missing or its referring to the charcoal canister I'm out of ideas. Thanks y'all, always helping me out!

You have to get a smoker out to find the leak - the J tube on the canister is a typical leak spot, but its really hard to inspect these without smoke.

Thanks for the reply! I already replaced the j hose as I mentioned but I'm looking for other areas that typically leak.
