Trouble code P0422 means: Main Catalyst Efficiency Below Threshold (Bank 1)
Trouble code P0422 means: Main Catalyst Efficiency Below Threshold (Bank 1)
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.
Trouble code P0750 means:Shift solenoid A malfunction

In UK it is code LS smartsilver
I believe it is a input speed sensor. Hyundai calls them pulse generators on the 99 elantra.
its a 10 gallon usually
