The issue is that the system randomly checks the loop of the fuel system to confirm that it has no leaks. A missing cap is the easy one to correct. It might also be a slpit in the rubber hose that connects the fuel fill tube (on the chassis) to the one on the tank, or any other hose in the the entire fuel delivery/ fume recovery sysrtem. The solenoid that allows the engine's vacuum to be used to conduct this test can also be sticking so that after the test cycle, it doesn't reclose. Good luck

cheapest thing is get new gas cap, next make sure no vacuum leaks anywhere, the you may need to replace evap purge valve. these systems are junk on all cars and will make you spend lots of money.

Tips for a great answer:
Evaporative Emission Control System Incorrect Purge Flow
What does that mean?
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.
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
A code P0441 could mean one or more of the following has happened:
