I would not worry about it unless you have drivability issues. Sounds like something electronic and not mechanical with all those codes. If the light went off and you dont notice any difference then maybe it was a fluke or a ghost code that got tripped. I was getting the 2262 code and ignored it after the dealer said they cleared it and it popped back up. After a month the truck stopped throwing a fit. This trucks are more picky than a woman on the rag.

Key thing:
Put the key in the ignition. Turn the key on and off three times and leave the key on the final cycle it scans and reports codes in the odometer read out.
