Been getting is code for about 2 years now and I’ve replaced the my o2 sensor multiple times and nothing has happen. Is there anyone that has got this code and know how it fix it ? I have Catless downpipes.

I have checked the wires and they aren't bad, it could be possible that I replaced the wrong one but I have replaced both bank 2 o2 sensors.

It’s not the sensors, it’s because your catless. I had the same thing when I had catless, and all those other related codes. I put the oem back on, and they all disappeared. I had to run cats for inspection.
