Which part number is the Bank 2/Down stream O2 sensor? 4011 or 4098?
1247511
I'm sorry. I purchased it for someone else so don't have access to it to be 100% sure. If I recall correctly, it was for a catalytic converter with only a downstream sensor. The 2000 Acura Integra GS it was purchased for only had one oem o2 sensor plug for the cat. I believe the part number was 4011. Hope this helps.

4098 has to be your bank 2 sensor , bank 2 is after your cat, and has a rubber boot on it.

4092 is the one after the cat....u have the one you can see just poping the hood which is 9005 I believe. BTW the are excellent quality for the price....so yes 4092 is downstream after the manifold

Before you buy it, go to the denso website at densoautoparts com. You can check your fitment there to be sure the amazon information is correct. For your car, the correct upstream (before your catalytic converter) sensor is 234-9004. The correct downstream (after your catalytic converter) is 234-4122. The item you are looking at here, the 234-9005 is not the right sensor for your car.

james, go to the denso web site and look up the part number. That is the only way I know to be certain that 234-4189 is the correct part number.

Just because you have an o2 sensor code it does not always mean the sensor is bad. You may have a problem with the wiring or an exhaust leak

Most Toyotas 1996 and newer have at least two O2 sensors - one before the converter and one after it. "Downstream" refers to after the catalytic converter. "Upstream" refers to before the converter.

Depending on the year of the vehicle it may not matter. My truck used the same O2 sensor in all banks.

There 2 places where the oxygen sensor is installed/located. Upstream and downstream. You have to check with your mechanic which one is not functioning. It happens to me also and I found out that it's the downstream which is no longer working. The upstream is just fine as it was the one replaced. Normally, it should be replaced both at the same time.

I am not sure what you mean by down stream. We used the part on a 1997 Toyota 4Runner. It replaced the oxygen sensor on the front side. The removal of the old part and installation of the new part took less than fifteen minutes. The new part works fine and we longer get the check engine code that indicated the original oxygen sensor had failed. We saved $160.00 by purchasing this part from Amazon and installing it ourselves. In fact, my grandson crawled underneath the car and did it for us. As for finding an answer to your question, you might do an Internet search for upstream vs downstream oxygen sensors for your automobile. Autozone or another auto part shop will check the check engine light code for you for free. Toyota wanted $49.00 just to tell us what code had caused the light to come on. My son did a search on the Internet to find the lowest price replacement part. We were delighted with the results. We got the part quickly and it fixed the problem.

This fixed Bank 2 Sensor 2 on a 1999 Lexus GS300. Denso is the same as the original sensor and works perfectly.

That's exactly the sensor I ordered on Amazon and replaced the downstream oxygen sensor located under the body of my 2005 Honda Civic. It comes with connector so you do not need care about rewiring to old one

2134-9028 is a down stream sensor(after the cat converter). 1135 is the code to replace the upstream sensor(before the cat) - fuel mix sensor.

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.

The pictured item (Denso 234-4189) is downstream of the CC. Cable is longer to reach the connector under the passenger seat. I bought and replaced both this one and the upstream sensor (Denso 234-9001 Air Fuel Ratio Sensor) in my 2004 Tacoma.
