P0455 code
A little background: I had the EVAPORATE canister vent solenoid replaced one year ago after getting a CEL. This summer light went back on showing P0455. Replaced the cap and all was fine for a while. Now it is on again. When I clear the code it stays off for week or so and returns. It once went off by itself right after fueling. I am aware of the fuel tank problem, but never smell gasoline. Any suggestions or ideas?
Thanks in advance, Jim

Might be time to do a smoke test.
Diagnostic Aids
• A fuel fill cap that is left OFF after a fuel fill will cause this DTC to set.
• A loose, missing, or damaged fuel fill cap can cause this DTC to set.
• A blockage or restriction in the EVAP purge solenoid, purge pipe EVAP canister, or vapor pipe, can cause this DTC to set.
• A temporary blockage in the EVAP purge solenoid, purge pipe, or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system.
• To help locate intermittent leaks, use the J 41413-200 to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT .
• To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT .
• Observe the Freeze Frame/Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition occurs that caused the DTC to set . This may assist in diagnosing the condition.

Just had both my fuel tanks dropped and new sending units, fuel feed line, crossover pipe and sending unit fuel lines replaced. Noticed a smell of gas after fill up. Bring it back to the mechanic that did the repair tomorrow and bringing a purge solenoid with me but he suspects a loose hose connection.
