I bought a new gas cap and replaced it, but light still on
SOURCE: Check engine light keeps coming on replaced gas cap already
Your problem is in the evaporative emission system which is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. The light coming on can be caused by one of the following:
1. Defective or loose fuel cap
2. EVAP canister or hose cracked- not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine
Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. You have tried the easy fix, the gas cap. Finding the leak now will require special equipment and testing procedures, might be better left to a professional.
Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

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!
SOURCE: Gas cap warning light is on. Gas cap is tight.
If the cap is tight then you need to replace the fuel cap. the light will go off when cap is replaced

Directions are in the book, but you would put the key in and turn it all the way, just don't start engine. Pump gas pedal all the way to the floor 3 times slowly, but it has to be with 10 seconds. Turn key off and when you start again, oil changed chime and warning should not be on. If it is, try again.
