The code you have is P0440 : GENERAL EVAP SYSTEM FAILURE . To repair this I would Use a hand held vacuum pump to determine if the NVLD is switching correctly. Connect vacuum to the line at the NVLD coming from the evaporative canister. Block the vent on the opposite side of the NVLD Watch the switch state on the DRB menu at roughly 1" hg the switch should close if not replace NVLD if yes find restriction between the NVLD and the purge solenoid.
