Is this a good replacement O2 sensor?

[Empty V]

So I'm cleaning my bank 2 position 2 O2 sensor right now but I think I'd rather just replace it with a new one because it's a pain in the @SS! Has anyone used this one? Replacement O2 Sensor

Here's a list of them, which would you choose? O2 Sensor List Is it worth it to spend the extra money on one with the connector or just save the $$$ and splice it in?

when i asked about replacing an 02 sensor everyone on here said not to take any chances and just get one from the dealer.

Interested to see what everyone has to say

Well I went to the nissan dealer yesterday and they were asking about $250 for 1 sensor!

If you can wait they sell genuine sensors on ebay for like $125, Im pretty sure courtesy has them pretty cheap aswell. Id personally stick with oem, these systems are far to finicky. I also like the idea of not having to mess my wiring to try and get a universal one to work.

Have you tried cleaning the old one though? They usually just get plugged up and you can make them last alot longer, Ive washed a few in water for a day, then a gas bath, put them back in and they work great (no code anyways)

Obviously the cheapest option

I replaced one of mine with a Bosch universal. If you go this route make sure you solder it properly. My dad was a MBZ master tech before he retired and used these all the time. He soldered mine.

Another option is to buy a NTK (NGK) replacement. When I was looking for one for myself, I found out that NTK is the oem supplier for Nissan. I think I found the NTK replacement for around $50 with plug.

Ok, I can't access your links... but try this:

Depending on sensor around $100 to $150.

I bought my O2 sensors on ebay and they were direct replacements, no need to cut any wires or solder anything, connectors fit exactly, haven't had any codes or issues since the replacements.

I'll see if I find the listing online and link it to you. I think I spent like 90 for all 2 but don't quote me just yet.

Here you go, this may not work for the 2001 QX4, but when I was buying both sides I had asked the seller if they would work. I had the item numbers and I wanted to confirm that they were the correct items.

You may wanna contact them and ask if they have for the 2001 QX4.

Thanks Mikey, I just sent them a message asking for specifics. After 2 days of soaking and finally breaking down because I hate the way my QX4 sounds I reinstalled my faulty O2. It hasn't thrown a code and is staying in the proper voltage range but I'm sure that will only last for so long.

I bought the same one from dealer but they charged me 150 for the senor and 106 for install + flash. That's CDN

UPDATE: So it's been a week since I put the cleaned 02 sensor back in and it hasn't thrown a code yet. I've also been monitoring it ever other day with my Code reader and it's been operating at the correct voltage. Hopefully this will last for a while.

Just soaked in gas right?

That plus blew it out with an air nozzle which really didn't do anything. Sat in gasoline for 48 hours. 36 would have been better but I couldn't stand the sound any longer and the car had to be driven.

Almost forgot, NGK makes the stock o2 sensor so don't buy from the dealer, unless you can get it cheaper which is doubtful.

It worked for a few days then the code reappeared. Both of the position 2 sensors are after the catalytic converters and I believe are only for smog purposes. It's the before cat sensors(position 1) that help determine fuel mixture. So if either of your position 2 sensors go out you shouldn't see a difference in the performance. If you're going for a smog check and can't fix it in time I recommend the gas method.

Thanks for info Billy. We do have emissions tests here, I was able to get the light to go out before I took the test. It stayed off for a few days. Was grabbing at straws thinking my gas mileage might improve if I replaced it. Wont be replacing the sensor-saves me some money and scraped knuckles. By the way to those looking for replacments, NTK sensors are original as posted - Summit and Amazon seem to have the best prices on them. Thanks again.
