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.

You likely won't notice any drivability problems. P0442 indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. 
The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage.
Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

With a P0442, the most common repair is to Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back. Otherwise, replace the gas cap, or Inspect the EVAP system for cuts/holes in tubes/hoses.

Good luck and hope this helps

PO442 means you have a small leak in your EVAP system. Most common cause is a bad gas cap, replace the gas cap with a factory gas cap,after market fail or does not conform to the OEM EVAP system. Other cause would be small leaks in the EVAP vacuum lines. P0445 is also related to the EVAP system and has detected a large leak in the system. Start with the gas cap as mentioned above. P1685 Is an issue with the ignition not recognizing the ignition keys and the car's ignition immobilizer my activate leaving the car not being able to start. That's going to have to be a Dealer repair. Good luck and hope this helps.
