This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
have all those things checked and come back to us

good chance it's your gas cap. Mine was never super secure, ended up throwing that code after I dried it off with a blower. Even after reseating the cap, the code didn't clear. I replaced the cap with an OEM one and I still had to have the code cleared at the dealer. No worries since.

+1 on gas cap.
you can just go to Autozone and use their OBD scanner tool to clear the code.
I put some motor oil on my finger, lubed the rubber ring on the gas cap, put it back in place, went to Autozone to clear the code... job done. No problem since.
