This code means the evap system is leaking somewhere which can be caused by leaking lines under vehicle near canister, fuel cap, or Canister Closed Valve (CCV), on or by the air filter housing, and verify the hose is connected and not pulled off. I'd recommend replacing fuel cap and doing a good visual inspection of hoses. Beyond that it may be better off for a shop to diagnose, a smoke test is the best test to have done so leaks can easily be found. I'd expect around a $500 repair at shop depending on what problem is. This code is only emission related and will not effect performance, cause you to break down, of lead to more serious problems. Let me know if you have questions, thanks.
