Code P2404. I changed the purge valve. I looked around for any cracked hoses, and I found out that my vaccum hose had to be replaced, but that had nothing to do with the P2404, it was for bank 1 running lean.
Now, it might be my Leak Detection pump, but I have no idea where to spot that. I follow the line that's supposed to go from the canister that the purge valve goes into, but it seems to lead back the same way as the hose that comes into the purge valve. I noticed that whatever this is, multiple hoses go through it, and I can see that it is cracked, and I can see some wires inside it. Also, where the purge valve goes into the canister, there's nothing really holding it in place other than a grommet, and there's a little piece of plastic sticking out the side of where the purge valve goes in the canister's grommet, like it's not meant to be there, and like it could cause a leak.
So, I guess this all leads to one question: how, specifically, do I get to the Leak detection pump? I know it's on the passenger side fender line, but I need more specific directions or pictures.
