The check gas cap is displayed when there is a leak in the evaporate system for the fuel tank. The check gas cap message is displayed because it is considered the most common fault by the factory. if you check codes there will be a evap leak code set, some common things are the canister close valve, leaking carbon canisters or leaking tube between the canisters, or leaking purge valve by the throttle. to check properly the canister close valve has to be commanded shut by a scanner or ids

I had the codes checked and they read:
P0455 : EVAP EMISSION CONTROL SYSTEM LEAK (large)
P1000 : MANF CNTRL FUEL&AIR METERING, AUXILIARY EMISSION CONTROLS
I erased the codes, and the engine warning picture. I was driving again and the
"Check Gas Cap" alert popped up. I turned of the car and removed the gas cap, I tapped the gas cap against a wall and re-installed it. I have not had a problem yet.
I guess I need a new gas cap?

P1000 : System checks not completed since last memory clear
P0455 : Evap (system) leak detected - large
The first P1000 is normal and will appear every time the codes are cleared until you've driven sufficent miles (or deliberately done 'drive cycles') to complete on-board monitoring tests. At this point it changes to P1111
P0455 possible causes range from the simple Fuel Cap off or Fuel Cap Seal defective through EVAP component physical damage or harness faults. The wall treatment points to the simplest - it's looking like the Cap.

the evap system is one of those systems that just needs maintenance as the car ages, the canister close valve will stick open/close due to rust falling into it from the vent tube which is metal...its gonna happen. Gas cap is cheap to see if it fixes it, but if I were a wagering enthusiast, i'd put a chip or two on the CCV - vent tube combo. let us know how it goes please!
