O2 sensor in bad location on my 2006

[Lars]

Got a PO137 code the other day. Bank 1 Sensor 2.
I have a 2006 Aveo and I`m looking at an O2 sensor from the bottom of the car near the front passenger tire. Is this the correct sensor I`m looking at? Hope not, looks like it will be a pain in the ass getting a wrench on.
First I`ll need to take a couple bolts off that are holding a plastic shroud in place to make a little more room. There is a metal shield under the senor preventing me from getting an open view to put a wrench on it. I`m not sure how to get any leverage on a wrench once I can get one attached?
Also is there a special wrench I can buy at a hardware store or rent from Autozone or O`Reillys? Like a 3/4 of the way closed socket.
Anyone have any words of wisdom for me?

First a disclaimer that I haven't had to replace it on either of my Aveos. That said, I don't think it would be a problem getting around that stuff. But you don't use a wrench for this job. Autozone (and maybe others) has a loan-a-tool program (buy then return for full refund), and you can loan an O2 sensor SOCKET (set) using this program. Thread the wire through the side of the socket, put an extension and a ratchet (or breaker bar if necessary) on it, and it should turn right out.

You should be able to buy or rent an Oxygen sensor socket pretty cheap, and you'll be able to attack it from the bottom. They look like this:


The sensor will come out easier if you work on it while the exhaust is hot.

OK, I will be visiting Autozone.

This is the correct sensor?

that is sensor 2, if that is what you are asking.
