Yes. I believe it is the Bank 2 rich codes that is triggering the CEL.

While it says "Rich" i am guessing what is happening is that you have a vacuum leak adding too much air ad the DME is adding too much fuel to compensate, triggering rich code and CEL.

I would start with a visual inspection of the rubber intake boot(s) and see if there are any cracks in it, particularly in the accordion section...If not obvious vacuum leaks, then have a smoke test done.
