2C7B Lambda probe behind catalytic converter 2, signal

[King-ishmael]

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.

Wire issue or you replaced the wrong one

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.

Any updates on this issue. I've had the exact same issue for the past year. Swapped in new sensors and no change whatsoever.

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.
