I'm getting check engine codes P0171 and P2A00 on my Honda Fit 2008. These both appear to be Air/Fuel injector readings. The weather has been terribly cold. I fueled up on Sunday, and the error showed up on Monday. I tried tightening the gas cap, but that didn't clear up the error. Firestone says they can't read code P2A00 (dealer specific) and Honda refuses to tell me what it means without running a $107 diagnostic.
A friend recommended disconnecting and reconnecting the battery. I'm going to try that tonight. My question is, is it true the battery could be causing these errors? My battery is from 2008 and I've been expecting it to die for several years now, but it's still running with healthy read outs for it's age. Is the battery causing these errors?
