Service Engine Code Help
I got this code while driving normally this morning. Does anyone know if it was just a glitch or is there something I can do to fix this problem? This is what I was able to find out online. Any extra help is appreciated!
P0456 - EVAP Control System Leak Detected (Very Small Leak)
Description --The PCM monitors the complete EVAP control system for the presence of a very small fuel vapor leak.The system failure occurs when a fuel vapor leak from an opening as small as 0.508 mm (0.020 inch) is detected by the EVAP running loss monitor test.
Possible Causes --Very small holes or cuts in fuel vapor hoses/tubes. Loose fuel vapor hose/tube connections to EVAP system components. EVAP system component seals leaking (refer to Possible Causes under DTC P0442).

And yes i clean inside the gas door area.

I reset the light and I took the cap off and put it back on. Everything seemed fine with it. Took the car out for a good 45 minute drive and no more light came back on. Seems fixed for the time being.
