2004 hyndai Santa fe with code Po441

that is an evap emissions code. basically it is fuel tank isn't holding pressure. not a big deal at all your gas cap might have been loose or may be leaking replace your gas cap and drive it for a little while to reset your "drive cycle". if it doesn't go away on its own then have it diagnosed for possible fuel fill line cracks or tank leaks.

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code

Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

I have a 1997 caravan and i got a po441 code what

You will have to test the purge solenoid that vents fuel vapor to the charcoal canister ( or back into the engine ) with a multimeter, check for ohms resistance per values set by dodge, the values are in the haynes repair manual.

2003 toyota highlander OBD code's po442/po446/po441

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal
