I have a 98" Civic EX and I have the error code P0138 coming up. I am fairly certain that the oxygen sensor is gone (it has almost 82,000 miles on the original sensor). I did not change anything else on the car and have not for several months when this came on. I purchased a replacement oxygen sensor for it that will bolt right on.
I put the car on ramps and looked under the car and see that the second O2 sensor is on top of the exhaust behind the cat with very little space to get it off. I can not get my normal oxygen sensor drive socket on because there is no room and also have trouble getting a flare nut wrench on it because of the position.
My question is how do you get this sensor off the car and how have other people done it???
It looks like I could undo the cat from the exhaust on one side to give me more room or fully take it off but it is rusted a good amount and would rather not risk have to replace all of those parts.
Any help would be greatly appreciated.
