These three codes have been persistent. I had a secondary air code but replaced the pump and now its ok. I have cleaned the MAF sensor. When I view live streaming data. Two of three O2 sensors have generally the same range and one is different. What should the range be? Should they all be the same? Are all o2 sensors the same?
1127 Long term rich Bank 1
1129 Long term rich Bank 2
1141 Load calculation crosscheck Range/Performance


Also, Can anyone tell me about the learning process? What it is and how to execute it?

I realize this post is over 3 years old. I'm having the same issue right now. What did you find out about your car? Are you still around? Thanks in advance.
