Now on to the code P0455

Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel). Can be anywhere in the EVAP system from gas tank to the charcoal canister.

If you search but can't find a leak, many shops can perform a "smoke test" where smoke is introduced into the EVAP system and where it escapes is where the leak is.
 
On my 01 the rubber hose split right by the cannister. The cannister is on the driver just before the rear axle on the floor pan. Visually I couldn't see the split but running my hands over the rubber hoses i felt the split. The doesn't sell the rubber separate, it's the entire rubber and plastic running to the engine compartment. I just got some rubber fuel line and modified it to work.
