DensoOxygen (O2) Sensor - 234-4261 (Fits Select Years of Toyota: 4Runner/Camry/FJ Cruiser/RAV4/Solara/Tacoma and Lexus: ES300/ES330/GX470 Vehicles)

Perfect length. Good quality and cheap enough that if it stops working you can just buy another. Easy to put on if you have an older car use spray to be able to break the rusted bolts if not it is plug and play. Works well quality is good. Denso makes great stuff. Removed the codes I was getting. No issue with sensors. Well made. No more codes.

I used this to replace the factory original sensor in my 2001 4Runner with over 260,000 miles. This sensor fit perfectly in the exhaust pipe with no modification needed at all. The OBD-II status is showing an "OK" once it has been installed and it has been working perfectly for over 5,000 miles. I hope this lasts another 1/4 million miles!For those who are replacing themselves, please be prepared for a bit of effort to remove the old sensor. I soaked mine in PB Blaster numerous times over several days but still it wouldn't budge with a quality crowfoot and breaker bar. I finally used a dremel to cut the collar of the old sensor off, then placed a deep-set impact socket on the sensor. I used an impact u-joint and an extension to get my impact wrench in there to try to loosen the hold. This still didn't take it off. I let the sensor soak overnight in PB blaster again, then tried the same socket with an extra long breaker bar (I think the spring of the u-joint may be taking too much of the impact). Voila! got the beast loose! I drive my rig on the beach and in mud and snow so I wasn't shocked that it didn't want to come loose. All I can say is be prepared to be *very* persistent with the old sensor!

Great O2 Sensor. I had a P0430 code. I have a 2003 4runner V8. I had to change the passenger side downstream O2 sensor. And this sensor worked perfectly the way it is intended to work. CEL has not come on after installing this O2 sensor. Passed the emission test with flying colors.

hi, from Cambodia.the products is best fit to my gx470 2003! plug and play.it's my 3rd order of Oxygen Sensors through amazon.

THIE IS BULL ***** the sensor doesn't fit the toyota camry 2002. i just install it today April 14 can i return it?

After reading all the reviews and comments, this was the easiest fix on my vehicle ever! The check engine and traction control lights came on and I had already replaced the fuel cap a few years ago so it couldn't be the cap. I took my car to my local auto parts and the check engine code showed a bad O2 sensor. The clerk told me they had in stock and it was going to be $180.00. However after a few minute he told me nope this was a special order, and it was going to take 2 days. They have done this to me in the past so I went home and found the part on Amazon for $96.00 (I think they order online and resell at a 100% mark up). They also told me the wrong part, the part for $180.00 was for an fuel/air sensor, which is totally different from O2 sensor. Physical differences: O2 sensor attach directly to exhaust pipe with built in threads, fuel/air sensor has 2 flanges for 2 bolts.Installation only took me 5 min, and here are the steps I used:1. Parked my car so that the middle of the vehicle is where your drive way and the street meet. Usually there's a dip there like at my house, this gave me an extra 3-4" to crawl underneath the vehicle.2. Remove the gray plug using a flat screwdriver. Insert the flat head at the top of the plug and pull, it should come off easy.3. Spray some WD40 or liquid wrench on the nut part of the sensor, and let sit a few min.4. Remove sensor using a crescent wrench5. Install new part and tighten with wrench, replug the plug and you are done!I started the engine and no check engine light or traction control lights! A few reviews said it takes a while for the lights to go off so I might have gotten luck. I hope this helps someone.

Not the right part to fix code p0037. You will want a downstream RIGHT sensor for that.

Installed easier than expected. And fixed engine error light. I highly recommend investment in a $150 level scan tool for your vehicle. This was a relatively easy DIY fix since I knew what the problem was. Note also you might want to buy a special O2 sensor socket that has an opening for the sensor wire. Also you might need a breaker bar and Liquid Wrench or WD-40. I also had a portable torch ready for adding heat but it turned out all I needed was the Liquid Wrench and breaker bar to remove the old sensor. The hardest part actually was getting the wire connectors apart. I used a vise grips to make an edge on one side and then used a flathead screwdriver to pry the thing apart. Be patient and you will get it.
