Just welded exhaust tail pipe back on to flange and codes still there

Answer 1

So you had an exhaust leak? did you reset the code? the code does not go away by itself. disconnect the battery for 30min or so if the light still comes back and there is no issues like exhaust leaks or issue with the engine replace the bank 1 sensor 1 oxygen sensor
