Hey guys im wondering where I can find a decent front O2 Sensor for my Maxima .
The only ones I can see are over a 100$ which is too much.

Have you checked www.rockauto.com ? I have bought many from the Rock. I see Rock has up stream NTK/NGKs for $48.79.

Also, if I'm in a hurry I will pickup an NTK/NGK from advanceauto.com and use the TRT30 coupon code and specify store pickup so you don't have to pay shipping.

I just checked www.advanceauto.com and applied the TRT30 code. It brought the price down to $53.89. The NTK/NGK brand is about as good as it gets for our cars.

I usually replace O2 sensors in sets (like both upstreams) to give both banks full benefit -- that is unless you recently replaced one already.

As soon as I buy a used Maxima with say ~150,000 miles, I usually replace the O2 sensors the within the first month. I'll immediately notice better pep and responsiveness with a little better MPG around town.

Yupp I usually grab my parts from there , but the price with the shipping is just about 100 $ since im in Canada

I usually get my parts through Amazon.com. The cheapest choices they have come without the connector ends. You will need to splice your ends onto them. I recall paying abour 40 dollars each. I have no clue what imprt fees would be in Canada. Do Canadians have a company that has internet-based discount parts? It might be worth looking into to see what they might have.

Oreillyauto auto, and autozone have the Bosch o2 sensors which are oem if u need it right away. But online is probably cheaper.

Bosch is NOT OEM. NGK/NTK is. Bosch does not work well in our cars according to many accounts from members here.

The last O2 sensor I replaced had both a Nissan and NTK stamp on it.

Bosch works fine for me.
O2 Bosch I say ok, Bosch plugs no way.

I'm having issues with my max and its calling for the front o2 so I figured I'd just replace both found some one Amazon for about $40 shipped so I sad that's the deal gonna get them, go out to the store and this "Certified Nissan Tech" hears the issue I was having saunters over and tells me (think boomhaure) "Yep souns to me like yew need o2 sensor". We converse for a few and tells me that the o2 from a 97 pathfinder would work and that all I'd have to do is mod the wires.<-wtf um OK all you real Nissan Tech's out there is this true or is what I believe true... 2 DIFFERENT CARS 2 DIFFERENT SENSORS. WFT even my girl was like um babe aren't those two different cars. Score. He says he has two and I can get them for 15 a piece I pull it. Um $30 and I'm good of course I'm on it but not without consulting with the org. Thx


To the op sorry didn't mean to slice your post.

I got one from amazon for $25 about a year ago. The connector fits, and it works fine.

my 99 cali has a code for this o2 ish too, i knom cali maxes have 4 o2's, are 2 upstream and 2 downstream?

Cali spec has 2 upstream and 2 (1 each) after the pre cats. The non Cali spec 4th gens only have one downstream mounted on the main cat.

i wish i had the courage to do that 95 ecu pin swap, such a pity too, consdering that i have a 95 and a 98 ecu lying around, tssk tskk, i hate myself, lol.

I have 2 codes i just checked today which appear to be for the same sensor: P0159 and P0158, Faulty Rear Heated Oxygen Sensor Bank 2, Sensor 2. Where is this located?

Last time I got o2 sensors they were about $30 each on ebay. Had no problems with them.

I just replaced all 3 O2 sensors in my I30 last month. They were the originals and Mother Bears to get out. The plastic plugs crumbled from the engine heat with 133K on them. They were stamped Bosch and that's what I replaced them with. So far no problems. The car is running fabulously. I'm happy. The were about $35 each.

i believe the rear is behind the cat(if i remember correctly)

on ebay i found global automotive selling ntk 02s for under $25.00

I used an NTK O2 sensor from rockauto on my 1996. It was well priced and works great.

just a note on the bosch. when I replaced all 3 several years ago , I bought the bosch from amazon and when I opened the box was a bit surprised to find exact oe NTK parts in the box.
these are the 2 part numbers
Bosch 13242 Oxygen Sensor, OE Type Fitment
for the fronts. currently 46.15 from amazon
Bosch 13783 Oxygen Sensor, OE Type Fitment
