2001 4 liter downstream oygen sensor on rear bank, how on earth do you get it out? It has the California emission with the four sensors, this the one at the back, in between the Y. I can get a open end on it, but there isn't enough room to turn, even if I clip the wires I don't think a long barrel socket would work. Surely somebody has a better way.

 

Torch? lol sorry, ive never done an o2 on anything besides a xj

 

 

If you are replacing it cutting the wires and trying a regular socket may help you out. looks like you may be able to do the up and behind thing that way. Getting the new one in may be easier with the old one out of the way. have you thought about a racheting wrench?

 

when it replaced my O2s on my 01 4.0l, a box wrench helped alot to break it loose. Cutting the wires did help also
