Two days ago my SES light came on, 2000 SE , after I read the code it came to P0138 & P0138 I have read every single post about the problem and understand that it is the O2 sensor AFTER the cat on the Fed. emission, no problem changed many O2 sensor in many cars.
My question: Which brand is the best for the our cars? Bosch? NGK?
Is the "universal" type really a good replacement?
Are the wires really going inside the car and should I have to pull up the carpet?

Thanks!

 

Hmm...I'm not sure what experience people have had with Bosch. I replaced all my O2 sensors to NGK a while back, about 5 or 6 years ago. I have yet to see an issue with them.

You shouldn't have to pull up the carpet. I didn't replace my O2 sensors, left it for a shop to do, but in working on my car on other items I see the wires being run around the unibody frame and engine.

 

Same idea here I had nothing else but bad luck with Bosch O2 sensor before, I always use NGK... Do they make the "universal" type or only plug-n-play? Which one does Nissan uses OEM ???
Thanks!

 

I don't think there is a universal type as each O2 sensor is specific to the car model (the sensor itself). Not sure about Nissan OEM, but it may be NGK. The Nissan OEM spark plug is NGK. Just call your local Nissan dealer and ask them, they will probably tell you.

 

will probably call the dealer in the morning
when I said universal I mean the one where you have to cut the wire harness from the original and connect the wires to the new o2 sensor.

 

Nope...the NGK come with the full harness. Just plug and play.

 

Stay away from the universal types. Not worth the hassle of splicing them in. Plug and play are about the same price.

 

So the NGK/NTK is the the best one the car??? I found a few on amazon for about $72 shipped seems really reasonable price for a plug-n-play!

 

Old thread, but I just replaced the rear heated O2 sensor on a federal-spec (non-California) 2000 maxima with a Bosch 13969 that I got at a local auto parts store for about $72.

The worst part of the job was getting the old sensor off - even with lots of penetrating spray applied over several hours it took a bit of leverage. A shop with a proper lift and a 22mm wrench with a slightly different angle would have a huge advantage, but I think it's still a clear DIY.

The replacement is exact and has everything, including the two plastic snaps, round through-floor gasket, and connector. There is no need to remove the carpet or access the interior of the vehicle at all - the job is done entirely from underneath, as the connectors are just stowed up in the hole under the carpet for the ride.
