I am working on my moms 2001 c70 and its throwing the codes P0442 and P1633. For the P0442 code its looking seeming like from what ive read in other forumns, there is some type of leak in the evap system. Im trying to find the charcoal canister, but i have no idea were it is. Do i have to remove something to get to it, and if so does anybody know exactly where it is? Any help would be greatly appreciated.

 

It's been awhile but I believe 0442 can also be the seal on the GAS CAP.

Our '01 C70 kept triggering the SES light until I learned to put the gas cap on CORRECTLY every time.
