Hi all,
first of, I bought the o2 sensor from autozone cause it was like 75 bucks...
so I was underneath my car and spotted the o2 sensor behind the cat conv... so I pull out the little black cap that was covering the wires and pull it out, I was pulling the wires our and noticed that the plugs do not match????
has anyone had this problem or tried installing the rear o2 sensor themselves?? do i have the right one and does anyone have a pic or illustration of where exactly the rear o2 sensor should be?? how hard was it to install??

thanks a million..

 

I think you've found the right O2 sensor on the car and have the wrong replacement part. I ran into the same problem when I changed mine as I was given the wrong replacement part the first time and found the exact same thing you're describing. You probably have one of the front O2 sensors. I'd take it back and try again.

 

hey DkGrn95SE

thanks a lot for the help.. i couldnt wait so I ordered the o2 sensor from courtesynissan for about 100 bucks... oh well, i looked at it the minute I got it and it plug looked just like the one that I was about to take out so I am sure that is it...

thanks for the input and now I am really sure that the people at autozone dont know ****.!!!

 

That's exactly what has happened because when I ordered mine it was a direct plug up to the previous. You just got the wrong part. If you also got a 0304 code, go ahead and change the KS and it will make a big difference in your car. I changed the exact same two parts about a month ago and my car is running great now.

 

if you have installed the rear o2 sensor on a 95 GLE, can you tell me where you got the socket from and how you took it out? I went to autozone and [pepboys wnd they couldnt help me, the socket they gave me was about an inch in width,,, the o2 sensor that I got fr0m nissan is about half an inch in widhtll ????


any ideas please??

 

let's see...hmmm...i think that size is a...ADJUSTABLE WRENCH!!

 

I am confused,,, I went to Autozone again and asked them for the loaner tool to remove the rear o2 Sensor, sure enough they give me a socket that is about 1 inch in width, and the o2 sensor that I have is about half an inch.. do I have the wrong sensor or what? Am I looking in the right place underneath the car?? I am confused now.. please help... what tool should I be asking for??
thanks

 

I just use a Crescent wrench...
