    Hello I wanted to first of all, say thanks in advance to anyone who replies and helps, so my story I purchased a 2006 Toyota Prius I knew it had a bad battery and opted to have Toyota replace it, everything worked great, then I decided to change the transmission fluid myself and after doing so I went to drive and the check engine light came on, I took it upto Autozone and they plugged it in and the error came back as P2195
    they told me I had a bad upstream 02 sensor, but for the life of me I can't find where its at can anyone attach some photos were it's at, I'm planning on replacing it myself

    Nathaniel, I also have a p2195 code. Were you able to replace the Air/fuel o2 sensor yourself? Thanks.
