It's amazing how one code can fix all the codes.

bro… this did not tell me anything on how to fix it and you didn’t really describe in detail on what’s going on and how you could fix it.

Read the description at the bottom of the video. I described what I did first. It had a P0155 code. I basically only checked the air/fuel ratio sensor and it was not working. I changed it. And that code also fixed the p0440, p0441 and p0446 code. The First code I had was p0155 code. That is the only code I researched to fine the problem. It was only the 02 sensor that was bad. I did not go more deep into finding other causes because that was the problem and it fixed it.
