I borrowed a friends code reader for the day and I read the code and got error code P0440. Has anyone had this and what might the problem be? I cleared my code to see if it will come back or not. Since autozone won't do that in my area now. Any help is greatly appreciated
alright, I already replaced the cap, but never had the code cleared until now. i'm hoping i didn't mess up my evap canister cause it came unhooked. and dragged on the ground some
