Error code 2751

Car is driving fine but carly shows error code 2751 and check engine light is on. Any insights from the group?

Some say its the O2 sensor or TA failing. Just changed TA about a month ago. Original BMW TA.

Bank 2, O2 sensor.
You can exchange the left and right, then clear the codes. If they come out next time. Just pay attention to whether it has changed to back 1. If not, it may be bank2 O2 sensor cable issue.
