Your gas cap is broken or damaged
“Check fuel cap” light may be caused by damage to a gas cap on a Honda Accord. It is a rubber seal which may be broken, and therefore the fuel vapor is at risk of getting outside and disappearing as a result. Check fuel caps then; make sure if gas caps should be replaced.

A leak of the fuel due to problem with pressure
The EVAP system
“Check fuel cap” Honda indicator appears when there is not enough pressure which triggers the fuel leak. It is displayed due to the EVAP – Evaporative Emission Control system in a Honda Accord.
And sometimes the EVAP leak happens.
The fuel tank is a part of it, as well as a purge valve. The EVAP system with a purge valve keeps the needed amount of pressure, and when the pressure is changed, the pressure leak occurs, due to bad gas cap or gas cap problems.
The EVAP system will let you know about the EVAP leak by displaying a P0456 code with “Check fuel cap” message.
The “Check fuel cap” indicator also appears thanks to another system – On-Board Diagnostics (OBD-II scanner) of a Honda Accord – advanced systems with modern technology.

Most drivers prefer to buy the system to prevent more damage.
