Question about Cars & Trucks
My car reads "check gas cap" I have changed cap three times still reads the same after reset
Check rubber seal if there is one, then EVAP purge solenoid. Also dealer should have a smoke machine to pump smoke into the line to check for small leaks. Good luck

yes the light is because of the gas cap being gone (sets code in evaporative emissions system), replace the gas cap, disconnect the battery for five minutes and that will turn of/reset the light, make sure u have the radio code before u do this, if u don't u will have no radio after the battery is disconnected..

SOURCE: Check Engine Light won't go off
If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!

PO455 is a large evaporative fuel leak. A bad fuel cap is ONE of the things that COULD be the problem. Fuel system cleaning only lightened your wallet. Reading your post is confusing. Did all this start AFTER the Valvoline Wallet Flushing? If so , they left something loose or disconnected. I would find a qualified repair shop to fix the problem, and if it has anything to do with what Valvoline did, make them pay the bill.
