Number one oxygen sensor on 2001 Oldmobile silhouette

I can see and unhook the number one oxygen sensor on a 2001 Oldmobile Silhouette but cannot get to it with any kind of a wrench. Does anyone know how to get this sensor out or does it take a special kind of tool?

    How do you change the number one oxygen sensor? How do you remove this with a socket when it has wires connected to it? And also it isn't shaped like a nut for a socket to even fit. Please help!

Purchased an oxygen sensor socket from an auto parts store. Went from under the van up to the sensor and was able to take the sensor out and replaces using the socket. Wasn't hard at all took about 1/2 hour total.

My 2002 olds silhouette had a fault code for bank 1 oxygen sensor #2.So I changed the oxygen after the converter and the fault code is still there.I did un-hook the battery to clear the code.

Bank 1 sensors are all the o2 sensors before the converter. Bank 2 sensors are all after the converter.On bank 1 there is 1 for each side of the exhaust manifolds. Bank 1 sensor 1 is on the side ot the engine that #1 cylinder is on. Bank 1 sensor 2 is on the other side. On front wheel drive GM vehicles sensor 1 is in front,2 is in back, but stiil in front of catalytic converter.

Location of oxygen sensor unit on 2002 silhouette

Check the exhaust system first in the engine compartment area where the Manifold connects to the exhaust pipes then check under the vehicle just before the Catylatic converter and after. Some vehicles have 2 and upstream and down stream sensor. It is usually the upstream or the one closest to the engine that goes bad.
