My check engine light turned on, and apparently I need to replace the Bank 1 Sensor 1 oxygen sensor for my 2002 Toyota 4Runner. Is this the correct pa

Yes. This part is a direct fit for the O2 sensor BEFORE the catalytic converter.

Ask the company that sells it! But if you go to the Toyota dealer they give only 90 days parts and 12 months on laber and cost around $300.its a good quality sensor.I replaced 3 on my car 1- on 60K second on 90k and 3 on 120k my car is now 135k.All of them I got from Amazon good price!

If you have a OBD reader that has SRS Info, it will tell you which sensor is bad. I replaced both on my '05 Silverado and the system reset and is working fine. Both of mine went out at the same time. But you need the reader to be sure.

Its not wise to replace a Cat unless the exhaust system is properly checked for temperature differences between CAT and engine, then from CAT out. secondly the P0420 code is usually a oxygen sensor code sensor code in some Toyota's therefore I recommend you stop by a auto zone or advance outo or even Oriely's and have them check and confirm this code for you, its free. For the ECM it depends on wheather you want to buy it new or used, for new you can check Toyota, auto zone, advance auto, oriely's or even amazom. For used you can check a junk yards like pull apart, wrench it, and others for a used ECM. I hope I was of some help to you.

This part fixed my 96 4runner with the 3.4 liter. It had a P133 code and this fixed it. Bank 2 sensor one code wich is the 02 sensor before the catalytic converter. Hope this helps

To know for sure go to bosch.com. Find oxygen sensors and your vehicle/engine. I found in the 2000 model year some rangers with V6 use identical sensors on left and right banks and others with different letter in the VIN number use different sensors. Only bosch can tell you for sure, so don't listen to somebody who says "yeah it worked for me".

What I try doing with all of my home repairs is replace the cheaper to replace items first if you cannot properly identify exactly what is wrong. Codes will point you in the right direction sort of yet vehicles are very integrated with everything affecting everything else for the most part. YOu can very easily test the voltage/resistance (Look it up online) to positively identify if your O2 sensor needs replacing.

I searched my records but could no longer find the codes for my 'check engine' light. I had a review on Amazon which has more details than I can remember. I did have an Accord ULEV and it was fixed by this sensor. However, please check with Amazon. Maybe they would allow a return if it is not right. The first part I ordered from another site did not fit and they allowed me to return.

This is the answer I found on the net for your car: Your vehicle may be equipped with multiple oxygen sensors at various locations - it is suggested that all be replaced, or at least that all be inspected and tested.

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

It has been awhile but I am fairly certain that all 4 sensors are the same so should work just fine. After I installed mine, drove around and the check engine light went out on its own. Joe

As stated earlier Sensor 1 is air/fuel this is not the air/fuel sensor. What is the check engine code number?

For 2002 Tacoma V6, this is the O2 sensor after the Cat converters. It has the extended cable assembly that routes through the floor panel and connects under the passenger seat. This is not the A/F sensor that is located before the Cat's

Sensor 1 is always before the catalytic converter and Sensor 2 is always after the converter. On the RAV, sensor 1 is high on the manifold/catalytic converter (accessible under the heat shield), while sensor two is accessible underneath the vehicle (remove the black plastic piece connected to your bumper). Bank 1 is on the drivers side, and bank 2 is on the passenger side. http://www.toyotaownersclub.com/forums/topic/128709-2000-rav4-1az-fe-o2-lambda-sensor-bank-identification/

I had codes for oxygen seasors and misfires. I replaced them with new O2 sensors and all I have now is a misfire. My code reader tells me it's 3 cylinders that have a misfire.

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.
