I've been getting these CEL codes lately, and usually they go away (either over a few miles, or by a reset via ODBC). I make sure that the gas cap (original on a 2001) is secured after each gas fill up.

I inspected the hoses connecting to the evap canister, and they appear to be sound. But like all things aged, they probably need to be replaced. I likely cannot see the minuscule crack in the hose that is causing the condition.

With that in mind, does anyone have the part numbers for the hoses?

Or, should i just take it to a shop for a smoke leak test?

Does the pressure sensor that is on the top of the fuel tank really become defective?

Thanks for your help!
