Oxygen Sensor O2 Sensor 234-9036 Upstream Air Fuel Ratio Sensor Replacement for Nissan Altima Maxima 3.5L Rogue 2.5L Pathfinder Frontier Xterra 4.0L Infiniti M35 3.5L G37 3.7L

I live in a state that is draconian in their smog controls. If you do not have everything exactly as they want it you will have to fix whatever issue down to a bolt. This O2 sensor as well as a down sensor have been just what I needed in order to get my car smog ready.The sensor is well made and should last for a long time.This is an upstream sensor so it means it goes before the cat on your car. It is well made and is easy to install. Just undo one end and put the new O2 sensor there. Undo the other end and hook the other end of the sensor there. That is really how easy it is. There might be something in the way but for the most part most O2 sensors I have replaced have been easy to use. The car I put this on is a 2008 350z and had no problems.Once you have your sensors installed whatever code you might have should vanish, that is if the O2 sensor is the issue.If you are looking for a good, solid, well made O2 sensor for you Nissan check this one out. It will erase your code and give you years of use.

I had originally gotten this for my car, but I can confirm it won't fit a 2013 Nissan Altima SV 4-Cyl.I did manage to fit it onto a 2016 Nissan Maxima.It turned off my O2 sensor warning, but the light and warning would come back on and go off for a little bit after the replacement and reset. It eventually stayed off and it works fine. Installation wasn't bad, but it did take a while to fit the slot for it.Nothing too negative or noteworthy to say. It's not terrible and it's currently working. It's been a couple months since installation.

Fit my 2008 Infiniti G35 journey sedan just fine.I haven't noticed an increase in mpg yet but I just recently put it in.Seems to run a little bit smoother though!
