P0449 Code


What are the common faults for the P0449 code? To date, I have replaced the fuel cap and the Vapor Canister Purge Valve (GM Delco P/N 55573017). I re-set the code and within minutes, it returns.

Where should I concentrate my attention next?

Vehicle skill level: very high

Thanks for your help.
