I've searched and searched and didnt find much pics and info.

I got a code for Bank 2, Sensor 1.

I believe its the one in the front. But I have no idea how or where it is located on the car.. I feel like a retard because I cannot figure this out.

First of all is it easy to change? Secondly is it on the top or bottom of the car?

I know that its not the rear sensor, which I suppose is a good thing, because I think that one is probably more difficult to change.



I found this picture, I guess it helps a little. Does anyone have any other diagrams, pictures for a 95 maxima o2 sensor locations?

 

this preaty much explains everything .. open the hood and look at the radiator fans , across will be about three plugs depends on the year car you have but one of them will be for the front O2 sensor fallow the wire and whola there it is i think is a 22mm but can't remember is not hard unless you strip the threads just make sure you do it when the car is warm not hot .or you can just try when is cold .. hope this helps ..

 

Is there a reason you bumped two old *** threads? Could you not just have asked in the newbie thread?

The rear sensor is easy. Easier than the fronts, actually.

As Abimax95 said, it's the frontmost sensor, in the Y.
