This is a 2500 4X4 6.7L diesel. It has NOx absorber efficiency below threshold Bank 1 code. What is a NOx absorber, where is it, what does it do, can something else bring in this code? Which side is called bank 1?

Remove and replace both Oxygen Sensors with p/n 05149263AA. If your vehicle is still under warranty this may be covered. Also, you can try taking them out and blowing them off then replacing them, sometimes this works.
