Hello, im new in this area, and im trying to learn how to remove o2 sensor, becouse my car got problems with it. so i started to search info on google..
For now i readed car ecu with mpps v21, removed lambda with ADS Lambda remover (it said succed), and written back that file, no errors loaded, looking perfect, but i turn on my diagnostic tool, and on live data its shows that both lambda zonds are working before catalyc : 30%, after catalyc 100%, and its shows error : lambda probe after catalyc. So that means lambda is not decoded? or everything is ok? or also i need unplug o2 sensors mechanical way?

THANKS FOR RESPONSE ♥

P.S. SORRY FOR FOR MY TRAGIC GRAMMAR :'(
