Bank one is driver side. Bank 2 is passenger side. Sensor one is front, sensor 2 is rear. So your code is for the driver rear sensor. Do you have headers and high flow cats? If the answer is yes, the only way to keep this from coming back once cleared is to have it tuned out or use O2 sims. If you don't have headers/cats, it is likely you have a bad cat. I believe this is the cat efficiency code. Good luck and cheers.
