I see that the P2A00 is more than likely going to be the front bank o2 sensor, and that getting the OEM Honda part will be my best bet. The roads/parking lots have been icy, and sometimes ruts are formed. Is there any way a wire got pulled out or something? Or are the wires pretty much tucked up out of the way (If I had a garage and not an ice/snow covered parking lot I would stick my head under the car). Also is there a Technical Service Bulletin covering this by chance?

Now I am thinking the Auto Zone employee messed up the P0870 code, but I know there was another one that involved the transmission, I was thinking I saw something about circuit B on the OBD Reader's Screen. I checked the level of the automatic transmission fluid, and it looks spot on. The car seems to not have overdrive (when coasting it is like a manual transmission car, with engine braking or whatever you want to call it). Also for as long as we've had this car, the transmission hasn't been changed (it's at 63k we bought it at 38k)

Now are either or both these codes possible a glitch? Like should I reset them and see if they come back or start moving along.

Thanks for any and all help!

Edit: whoops, forgot to mention. 2007 Fit Sport with Auto Trans.

Edit 2: after some searching, I think the P0870 code should be P0847.

 

Just an update, the CEL/MIL whatever you want to call that light is now off. Driving around town today, nothing seemed out of wack. Will try highway speeds tomorrow.

If the P0847 does come up again, it seems that I should replace the second pressure switch and the part number for that is 28600-RPC-004. Is this correct?

 

Drove just fine on the highway.

But we have been having cold (below 0 F at times) with lots of snow and slush when it wasn't. Don't know if that has anything to do with the hiccups, but I believe the car is better now.
