Default KOEO Engine code 31(c) ?!?

I'll be the first to admit I know very little about these codes, but I have the Chilton and Haynes manuals and don't see a KOEO engine code 31 listed.

I followed the procedure on here for retrieving the KOEO codes and this is what happened
1st set of codes 11 (or maybe 111...can't remember)
9 second pause
2nd set continuous (c) codes
122312231
From reading the manual, the first 1 is just a prompt
22 and 31 are the codes (repeated twice)
22 says it is MAP sensor related
but I can't find 31...did I read it wrong? I did this several times to make sure.
