Ranger Posted November 25, 2005 Report Share Posted November 25, 2005 That is not an O2 sensor code if that is what you are asking. I think it is telling you that bank 2 (rear bank) is running lean. Maybe a vacuum leak. Perhaps a manifold gasket. Link to comment Share on other sites More sharing options...
Ranger Posted November 25, 2005 Report Share Posted November 25, 2005 Correction, Bank 2 is the left (front) bank. Link to comment Share on other sites More sharing options...
