KOER code help

Ok, so I'm still getting that code 66(my maf was .5v), but here are my KOER codes and if you could help it would be awesome.

55-check ECM pin 5, little or no power. What pin does this go to?
33-EGR did not open/respond during test. I'm guessing this relates to my KOEO codes 85 and 34
94-something about the air system
44-air system inoperable? relates back to code 94?
65- no clue

The fact that you can run a KOER self test = code 66 is not a "hard failure", a KOER could not be run if a failure code 66 is "current". If by accident you started the engine with the MAF disconnected, the code will be logged as a "memory" code, and it'll show in a KOEO. Suggest to clear codes (disconnect battery for 15-min.) .... and rerun the self tests.
