Looks like P0113 is setting off your CEL. I would clear everything and see what comes back. I would assume that one code will and not the others.

Not at home with my FSM but will be able to help later.

check your ground next to the alt on drivers side rail.....
also double check your maf connection as your iat is also included in the maf sensor..
wheel spin sounds like it would be a vehicle speed sensor???

H means it happend in history meaning it isn't going on right now...
only concern yourself with "HC"

that means "history & current"

C1225 is for left front Excessive Wheel Speed Variation. Some of the references have is listed incorrectly.
