are both upstream 02 sensor the same?

They are identical. Make sure you know where those sensors go: one is easy to see, the other one is a little bit more difficult to see or to reach (on the bottom middle side closer to power stearing). The idea is that there are two sensors, one for each 3 cylinders out of six in V6 models. Le tme know if you have any other questions

If you have the V6, both upstream sensor should be the same. Your diagnostic code should tell you if your problem is bank 1 or 2.I only needed to replace the bank 1 sensor and that solved the issue. Check out this web page for more info, (maybe more than you need, or want). http://www.autoshop101.com/forms/h37.pdf

I believe so! Just one in front and one in back! The code it throughs should tell you which one is bad.

yes, this sensor will work for both just fine. well atleast for a 2002 solara

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

Need to know the make and model and engine type of the car to answer this question. Are you asking about bank 1 vs bank 2, or are you asking about upstream vs downstream? Go to the Denso web site to see what sensor you need. http://densoautoparts.com/find-my-part/vehicle-selection

not sure their are two different versions.you have two get the correct one that matches your unit

Don't believe so but I know that this one worked, after I bought a different "cheaper" sensor that computer wouldn't recognize

1135 code is for the Bank 1, sensor 1. 1155 is for Bank 2, sensor 1. Both are upstream sensors and are the same for replacement. The other two sensors are a different type and different part number. When I checked Auto Zone for part before buying from Amazon I was told upstream sensors are both the same.

no this isnt. this is the upstream for the 1mz v6. there are two of the upstreams. i am unsure if your downstream wires in to the cabin like our sienna does

I suppose it depends on the vehicle, but in my 1998 Jeep Wrangler TJ, this is the upstream sensor. The downstream sensor is different, and its part number is Bosch 13138, though if you're buying for a Jeep I would recommend you stay away from from the Bosch and go with NTK/NGK. I've been much happier since I switched.

Same for both. I replaced both sensors on my 2005 Yukon 1500. Worked great.

I believe there is only one style downstream sensor and they are different style plug than the others.

Yup, only difference from the upstream sensor is the length of wire. Denso is the one you want

Same sensor. Just changed out all four using four of these. Went from 9 codes down to 3.

Go to bosch's website, it will tell you. I found for 2000 ford rangers it depends on one figure in the VIN number weather the two upstream sensors are identical or different.

Those threaded sensors were the upstream o2 sensors on my 4.7 tundra v8.. the downstream sensors had a bolt on each side to secure it. At least that was the case for my application.

Just look at the plug connector on the sensor your replacing, there are two types. Get the one that has the same style that needs replacing. Easy peasy!

If this is the part to match the pic, it's the downstream sensor on my '02 Tacoma 2wd SR5
