CHECK ENGINE LIGHT ON

2003 Dodge Neon

Computer problem
2003 Dodge Neon 4 cyl Front Wheel Drive Automatic 27772 miles

My check engine light is on. I found the code P0456
What can I do to fix the problem. I put vaseline around the gas cap and the light is still on. What next?

1st step would be a new gas cap
and reset codes
if light come back on a smoke test is needed to check for leak in the
EVAP system
