can you use this part to replace both O2 sensors, or is this specifically for bank 2 sensor 2?

If I recall right, my highlander used these for bank 2 sensor 1 and bank 2 sensor 2. I'd go on an auto parts store website and double check that the part numbers are same for your car though.

I believe it is the length of the wire only that determines the part # for O2 sensors. I used this sensor on my 2002 Toyota RAV4 for Bank 1, Sensor 2. O2 sensors are used for downstream (Sensor 2) after the cat converter. A/F sensors are used upstream before the cat. OEM link: http://densoautoparts.com/find-my-part/vehicle-selection

In RAV4 both O2 sensors are the same. In case of original Toyota spare parts the lenght of their cables are different, that's why the different part numbers. This Denso is delivered with the longer cable, so it can be used for both positions as postcatalytic (O2) sensor.

No it is just the converter, you cut your old one out and weld or clamp this one in. You dont even touch the o2 sensors

That code is for the upstream sensor, which is sensor 1. Sensor 2 is behind the catalytic converter. Bank 1 is drivers side, bank 2 is passengers side, at least on my Tundra. I can't say if it will fit your Lexus.

They are two different sensors, i recommend going to the Denso website to get the two part numbers. The upstream fails more often and the downstream one is usually cheaper.

Hey James, I just recently(within the past month and a half) replaced my o2 on my 02 Toy Tacoma 4x4 3.4L with an automatic tranny and this exact sensor #234-4189, working great for me. I am told by my mechanic that it is the same one for the manual trans. Hope this helps dunc g

The Denso 234-9021 is an Air/Fuel Ratio Sensor. Used two of these recently to replace both upstream sensors (Bank 2, Sensor 1 and Bank 1, Sensor 1) in my 2001 Toyota Avalon. The trouble codes that were set were P1155 and P1135. Use your OBD II tester to determine which sensor(s) have gone bad. The downstream oxygen sensors do not require the Denso 234-9021 oxygen sensor. By the way, the Denso part was an exact fit replacement and should be money well spent!

It depends on the car and the software you are using with this code reader, but mainly yes. As least if it did not tell you which O2 sensor is bad it will tell you that an O2 sensor is bad somewhere.

Harry, It appears that the Bank 1 sensor is an Air/Fuel sensor. Try looking up the part that you need at densoautoparts.com. The website is easy to use and should give you the P/N that your RAV4 needs. Good luck with your project. The Amazon website has the best prices for Denso sensors. Hope that this helps.

-go to automotive parts & accessories -enter your car info at the top left -do a search of "o2 sensor" -you'll see all compatible O2 sensors and be sure to read description to see if it's upstream or downstream. -also check to see that it's not a Universal sensor. Universal's typically don't have the connector you need.

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.

From what I can determine on the Bosch web site and the local VW dealer, this sensor can be used for the front or back O2 sensor.

Find you manual and make sure if your engine is 1MZFE. BTW, there are 4 sensors in 1MZFE, this one is for the code 1135(bank 1 sensor 1) and 1155(bank 2 sensor 1)

From my personal experience, it looks like there is no distinct difference. When I replaced mine, I wasn't too sure which bank it was so I tried both front and rear with the same sensor. They have the same end connection.

I'm not sure if this is for the downstream o2 sensor. Maybe someone else can chime in on that. It's bank 1 sensor 1 near the firewall and you can also use this on the manifold towards the front bumper. They are the same. Yes. This one comes with the wire and plug. Once you are able to break them loose installation is easy.

The page for this sensor has a compatibility function. Have you tried entering the information into the page and see if it is comparable?Failing that, have you called a car part store and asked what the part number is?

If your existing sensor looks identical to this one it should. I would contact and ask the seller to be positive.

My sensors also didn't look like the replacement. That said I read the description and understood that they were compatible. It's just two wires to the sensors and if you look at your owner's manual, if you have one, it's easy to install. I replaced the brackets with the package I received, it was working in minutes. The research I did advises if you are not comfortable doing the work, get a professional to do it; however, they are pricey. If you "You Tube" the subject it helps a little in understanding the topic.
