Both of those codes are for the 02 (air/fuel ratio sensor) in the header.

Probably a snagged wirre, or disconnected.

 

car drives fine.. i dont notice any power loss or anything.. it was really cold that morning when i took it out.. was at least mid 30s.. and i didnt warm in up before i left but the car is indoors.. every nite

also did 140mph once on friday.. after that i drove another 10 miles home car drove fine .. didnt drive car till monday.. drove it out for bout 15miles .. again car drove fine.. tuesday morning around 630am very cold mid 30s and didnt warm up car.. drove two blocks and didnt notice it till i stopped at a light.. did no more than 40 mph and didnt rev higher than 4k.. not sure if the cold temp might have set the cold.. i should really clear it too see if it comes back but any info would still help

 

Clearing codes on an 06 is not like previous cars.

Your going to have to get the Honda manual and have a read. Or take it to the dealer.

 

it's under warranty on a stock car. No need not to take it to the dealer. Your 140mph run won't be in the freeze data if it coded on a cold start.

 

On a Honda TSB that covers all 00-03 Honda's (except Passport for some reason) DTC P2A00 = Air Fuel Ratio (A/F) Sensor (Sensor 1) Range/Performance Problem. Can't find DTC P1172. I think a DTC starting in anything other than P0 is manufacturer specific. For example the generic OBDII DTC for a cylinder 1 misfire is P0301. The Honda manufacturer specific DTC for a cylinder 1 misfire is P1301. The only difference between the two is the P1 in the Honda DTC. That being said P0172 System too Rich (Bank 1) is a generic OBDII DTC which may be the same as Honda's P1 DTC. I don't know for sure, good luck.

EDIT: I type too slow.

 

Passports aren't real Honda's. Real junk, but that's another topic.

The generic OBD readers can't define manufacturer specific DTC's as well as the OEM scan tools, other than giving you the DTC #.

I don't have a 06 book here, otherwise I'd look into it.

 

 

P1172 AF sensor out of range, high

To be exact...

 

but that's all I can tell ya about it. Something with the primary 02
