You are going to most likely have to replace the Vent Shut Valve These are a known issue. The originals don't handle wet weather well. In the North they fail quite quickly because of road salt. I just replaced mine after 18 months of CEL. For the 98-99 4cyl it's the following: Search for Honda Service Bulletin 01-011 June 26,2001.
EVAP Control Canister Vent Shut Valve:
P/N 17310-S0X-A02, H/C 6197370.
It's not all that hard to replace. But there is one issue The bulletin has pics to show where the part is. Disconnect hoses, drop the whole canister to access the 2 phillips screws holding the valve in place. THE ISSUE... You'll want to grab hold of the plastic canister posts with vice grips to keep the threaded metal insert from spinning when removing the almost guaranteed rusted screws. Don't squeeze too tight or you'll break the posts. Too loose and you'll let the insert spin. If the insert spins, you'll have to replace the whole canister because the inserts will fall out.
