My manual, for a 2002, doesn't list that code. Codes close to 455 indicate a fuel-tank pressure problem. Check to make sure your gas cap is on tight - at least 3 clicks!

Things That Can Go Wrong With a Carbon Canister
Vapor system-related codes to know:
P0440 Evap Emission (EVAP) System
P0442 Small leak detected
P0446 System performance
P0455 Large leak detected
P0496 Flow during non-purge
P1441 Flow during non-purge
TIP: Some code numbers have changed recently. P0440 became P0455. And P1441 became P0496.
Carbon canister loose in brackets – The canister bouncing around breaks up the carbon and turns it into dust that can at times be found in the purge solenoid. This may not set a code unless enough carbon dust restricts the flow in the Evap system, or prevents the purge solenoid from operating properly.
Damage incurred by foreign objects striking the canister and breaking the canister body – This will cause major leakage during evap testing, possibly causing a P0442 or P0455 and of course venting vapors to the atmosphere.
