    Hey guys, so I am working on fixing this O2 sensor code that I have been having. Can someone tell me the location of 02 sensor Bank 1 Sensor 2?

    Just to make sure Im getting the right one if I replace it.

    Thanks

    Jeff

    On the 2010 or 2006?

    2010 there's a bunch of sensors on dpf and by exhaust valve. FYI, have you tried clearing the code and seeing if it comes back?

    On the dpf the 02 sensor is the one on the top right sticking out at an angle. There's either one immediately after the DPF paired with a temp sensor or one at the exhaust valve. One of those is probably sensor 2. This is just a guess so if you find out please share!

    It's on the 2010. That would make sense as to which one or is. I am trying to get the dealer to do it for me under warranty, but it came on at 36300 miles. So we will see.

    I'll let you know which one it ends up being.

    Hi Jeff, I just got P2271 fault code on my 2009 Jetta SW TDI. It is supposed to be O2 sensor signal biased/stuck rich in bank 1, sensor 2. I guess it is the same as yours. Could you please confirm that it is the one shown on the scheme above between NOx and H2S converters? Is it easily accessible from underneath? Thanks, Stan
