My car keeps having P0446. Dealer has found the lectrical connector for the rear canister to be corroded, and tried to repair by soldering in a new pin. Worked until I got a hour away from the shop. Called back and they said can't by just the part, must get the entire harness which was really expensive.

Anybody ever have to replace one of these connectors, where did you get the parts.

Have you tried a scrap yard? I pulled some perfectly good connecters from a junk yard...

I am having trouble with the same error code, and it driving me nuts... So I had the the same problem dealers says oh it is a corroded connection... so I test everything out just like the shop manual says from the ECU back to the evap drain valve and other little one that is up above... all the wiring is fine, and yet the car still throws the code.. so I replaced both the evap drain valve and the pressure release valve... nothing still throws the code... I did a scan with my OBDII scanner and noticed
