PO441---EVAP System Incorrect Purge Flow
PO440---EAVP Control System Malfunction
PO446---EAVP Vent Control Circuit Malfunction

I think a repair shop is your best bet to smoke test
system & resolve

you see code po441 the purge solenoid could be faulty or disconnected. if you have problem with evap switch to vent solenoid you would smell gas fumes in vechicle.check make sure gas cap on tight not leaking because it will set off code po441.

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

what kind of problem and how can be solved
sam

p0446 is an evap code for incorrect purge flow, check the rear vacume switching valve. its above the rear sub frame

P0420 is catalyst system efficiency below threshold (bank 1)

P0440 is evaporative emission control system malfunction

P0441 is evaporative emission control system incorrect purge flow

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
