Yeah, I ended up taking by the dealer. They replaced the connector and fixed the wires. They tested the vavle, and it was working fine. So far no codes have come back.

 

might be your purge 90910-12276 solenoid i think that's what is going on with mine i checked it and it seams to be malfunctioning. seams like it fails off which backs up the canister and throws leaking codes and prevents the car from runing properly and also causes a misfire in my cylinder #1; i bypased the 90910-12276 solenoid with a hose and it runs grate just runs lean acording to the code reader program i use

 

oh never mind lol see you got it working lol

 

Hey I have the same error codes, and mechanic told me to change the gas cap and the filler neck. They quoted $299 for it. Is filler neck something I can change myself? Is this a common problem for these codes (p0441, -0442-p0446)?
