Engine diagonstic codes

Does anybody know how to find out what the engine diagnostic codes
mean...

I have a new (5000 mi) 2007 Honda Fit for which the engine check
light came on. When I took it in to the dealer, they said they
reloaded the newest software, but that was all. I was told that
the diagnostic codes were P2A00 and P1172. What do these mean.

It's warranty claim time. Google shows:

P1172: Rotor control fault. P2A00 air-fuel sensor. according to:

Could you elaborate on the "warranty claim time" comment a bit more?

I read the url you referenced. While the same codes came us as in
the article you referenced, there are some differences.

1. I didn't run through a puddle, or have any other reason to
think there is water getting in the engine in any way.

2. In the article it mentions a loss of power. My car seems to
be running fine in all other ways, has no loss of power, and
seems to be getting excellent fuel economy (if you consider 38
average when EPA estimate is 31-40, sounds good to me).

3. The other possibly bad thing I have noticed, but am not sure
is that once when after pulling a long hill, I smelled a faint
smell like you get when you oil gets changed and they spill a
small quantity on the engine. This has happened once so far.

With reference to the P2A00 code, if the "air-fuel sensor " or
commonly called oxygen sensor(s) goes bad, then your 2007 is covered
under the emissions warranty. This should be fixed soon so you don't
risk damaging the catalytic converter. The conditions may be different
from that other owner, but if the OBD-II system tell you there is a
problem with the oxygen sensors, I'd pay attention.

There were earlier Accords with P0420 problems. Honda recommended
replacing the converter. I managed to help one owner fix it by
replacing the (IMO junk) Denso sensors with Bosch planar sensors. Good
thing I recommended that, otherwise that P0420 is going to come back.
But your sensors are probably different.

As far as rotor control goes, I'm really not familiar with this code.
But if you have traction or stability control, where the ECU actively
manages the brake force to the rotors then it too should be looked at.
If there is a fault here, again, it should be covered under warranty
repairs. And for safety reasons, I would pay attention to this too.
It's not like many OBD-II "gas cap loose" type of codes because the
pressure sensors were to sensitive.

I assume you'll have Honda look at the problems, right?
