codes not listed in the book

I pulled the codes 2x to make sure I was counting them right. I got 112, 615, and 721. Does anyone know what theny mean?

112 = Air charge temperature (ACT) sensor indicated 254degF. Circuit grounded

615 and 721 don't exist AFAIK. Triple check that you pulled them right. I'll double check my book as well.
