P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.
A FixYa rating from you regarding my assistance would be greatly appreciated.

There is a VSV (vacuum switching valve) , usually mounted on the back side of engine block, under the intake manifold, as well as the map sensor, that can also cause that code if one or the other is faulty. It takes some pretty detailed troubleshooting to confirm this in some cases, so if that's not in your line of work, you may have to have it properly diagnosed, or take a 50/50 shot at which one first.

I had the same problem, then took my car to an expert repair shop who diagnosed the sensors and
found no problem with the car. They notified the DMV who was unaware of the problem, who then told the repair shop (John's Bascom Automotive) that they will adjust their computer system to allow a "two speed idle test". My bill was $95 and I still have to pay for a smog test after driving around for
a couple of days to clear the computer monitors, a fair amount and I gladly paid it.
John advised me that I'd get no satisfaction with Toyota or the DMV. I went to the dealership where I
bought the car and they said that the smog stations don't know what they're doing. They charge
about $100 and work around the P0500 code but it takes them about two hours to do this. I told
them that I should have been notified about the dyno none-compatability by Toyota and that Toyota
should have notified the DMV beforehand. I wonder how many speed sensors are being replaced by
unknowing smog shops around the state. I got Toyota's main customer support phone number and
will call them Monday. I'm going to get my pound of flesh ($95 worth) from the DMV next week also.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.
more help, I suggest you to refer the help links provided below. These will let
you know more about which areas to look, check, when there is engine light
coming up on dash panel.
