Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front

Do not waste your money I bought this sensor thinking it was an authentic Denso Product and found out by the mechanic shop that it wasn't real denso Products are not this cheap in price.

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.

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.

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.

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

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

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.

Denso products are made for your Toyota. None better for replacement parts.
