The large leak could be a loose tank cap
code p 0441 refers to evaporative emission (EVAP) system--incorrect flow detected === causes ---hose /connection/s,-- intake leak--EVAP canister purge valve
probably need to replace the valve but test first for the large leak or cap loose fault as it may fix both
Very try I put a 99 accent cap on it cuz the cap I had in there before threw a code for the small leak then went away now it says all that new stuff and the evap i/m stays incomplete and I only can have 1 code and no i/m
Not gas cap same code on
replace the purge valve
Well replaced purge valve and canister valve same code p0441 large leak went away ...

P0441 : Evap. Emission System Incorrect Purge Flow
General Description
The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The ECM controls the Purge Control Solenoid Valve (PCSV) to purge any collected vapors from the canister back to the engine for combustlon. This valve is actuated by the purge control signal from the PCM and controls fuel vapor from the canister to the intake manifold.
Possible Cause :
● Leakage on hose to PCSV
● Defective PCSV

Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications.
Damaged, missing or improperly installed fuel filler cap.
Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
EVAP canister purge valve stuck closed.
Canister vent (CV) solenoid stuck open.
Fuel tank pressure (FTP) sensor malfunction.
EVAP canister leaking.
Fuel vapor control valve tube assembly blocked.
Fuel vapor vent valve assembly blocked.
Obviously the gas cap would be the easiest and cheapest thing to fix. Just make sure it is put on correctly and tight. If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material. Hopefully it is the gas cap and you can take care of it yourself. Good luck.
SOURCE: Check Engine light - Code P0441 (Evap Emission
There is an evap purge valve located in the back of the driver side of the engine. This valve needs to be replaced. Had the same code a couple weeks ago. Replaced that valve and the problem was fixed. Hope this helps.
SOURCE: I got a Error Code
P1442 usually gas cap. P1449 usually vent solenoid. P1441 usually always a faulty FTP sensor. Very problematic to Malibu, Grand Am Cavaliers and Aleros. That would be my first area to check. They are also known for poor wiring connections at the Left rear passthru connector to the fuel tank and vent solenoid, but not necessarily for that code.
