Code P0422 indicates that the catalytic converter's efficiency is below the threshold in your 2001 Hyundai Elantra. To fix this, first, inspect the exhaust system for leaks, as leaks can affect sensor readings. Next, check the oxygen sensors for proper operation, as faulty sensors may falsely trigger the code. If the catalytic converter is determined to be failing, it may need to be replaced. Always clear the code and test drive the vehicle to ensure the issue is resolved.
PO443 is an indication of a problem with an indicator lamp illumination. There are no drivability issues with this code, but safety could be an problem at night.
