My issue here is, I just replaced this, about the same time last year, so it is barley a year old. I purchased a genuine Honda OEM sensor, and am not sure why it would go again. The sensor I bought is part number 36531-RME-A01 from www.bkhondaparts.com. I did some research and read that I need to get my software updated? Is this the case, can an O2 sensor fail within 1 year of installation if the software is not updated? Dose anyone konw if Honda will perform the software update for free?

I have a 2008 honda Fit manual transmission with 65K.

Thanks in advance-

in order of finding:

P1172 is A/F sensor 1 out of range high
P0456 is a small leak in the evaporativeemission system
P2A00 is the fuel air sensor range/performance problem

You'll need to visit a dealer; the solution is not backyard correction except for the small leak. first and third are likely same fault with the sensor. And yes the O2 sensor can fail again but perhaps fixable under warranty if its not some contributor (which is why you need to see a competent dealer).
