The check engine light is on. the scan reads 441 and 445

1st. Make sure your fuel filler cap is tight, clean, and sealed well.
These are codes set when there is a fuel vapor leak.

P0441 EVAP Control System Improper Purge Flow.
P0446 EVAP Control System Vent Control.

This indicated a problem with the evap emission control system. This is the part of the emission controls that captures gas vapors in the tank, stores them temporarily in a charcoal canister, and then burns them by "purging" the charcoal canister into the intake.

Could be something as simple as a loose or faulty gas cap. Can also be vacuum lines for the purge valve and canister or a bad purge valve itself.

This code is infamous code, its a bit complicated if not mechanical incline, I would recommend finding an of duty Toyota mechanic to do a side job. There are plenty of those guys will do side work and will save you big bucks, however you will have to asked around when you get the next oil change. any repair manual will have proper instructions. same time, purge valve is either bad or clogged. i'd, also, clean EGR valve.

the cannister is mounted in the rear underside of car above the rear crossmember,you either have to remove the exhaust or lower the rear crossmember to gain access to the charcoal cannister.. there is also a vsv valve that mounts on the air cleaner housing.
these would be the 2 common items that can set these codes although there can be other issues that can set the codes you have
most of the testing is done with a scan tool . and vacuum pump there are a few test to do with a voltmeter.
