Best price I have found on Denso O2 sensors..

I do quite a bit of my own work and have owned both Toyota and Lexus products for years. When it comes to the O2 sensors, I insist on Denso as have had failures with other brands. This is by far the best price I have found on a Denso and the shipping was very fast; well packaged too,

Perfect fit and works good so far.  It already has anti-seize applied on the thread so it's ready for installation.  You'll save a ton of money doing this easy task yourself.  For this price, buy both of them (bank 1 and 2) and you won't have to worry about these sensors again.  Also buy an offset open end socket and you won't have a problem getting the sensor off and tightening the new one on.

Tried several sources, finally went to Denso site. And using old removed Sensor prod# got new product replacement.

Saved a boat load of money, spent me sweat equity to install sensor myself.

Never had a problem with the Denso O2 Sensors on our Japanese Vehicles.  They make quality parts and may cost a bit more, but my motto is buy the best and only cry once.

Had P1135 and P1155 codes on my 2001 Toyota highlander. Figured these sensors would make it go away. However, my vehicle requires Air/Flow sensor not O2 sensors. I know this price look more appealing than the ridiculous OEM price from Toyota; however, double check that your buying the right sensor.
Prime Auto Choice is good in terms fulfilling orders, they also have nice customer service, reachable by phone.

I believe Honda had original Denso sensor on the car in the first place. It failed a little prematurely with only 55,000 miles on the car. See how long this one lasts. Regardless, Amazon's offer beats my local parts store by far. Check engine light went off immediately after I replaced the sensor......Henry418sc

it works and is a perfect fit,save money, price for this at my local auto part was doble, no need to be doing modification this o2 sensor is ready to put it in just unplug and remove the old one install and plug in this one. I just install it two days ago thats the only reason i gave it 4 star need to see how it perform in the long run,so far its great.

Great replacement sensors for my 2003 Sequoia.  I'm always a bit leery about ordering electronic parts for my vehicles and finding out they are not actually compatible.  All research told me these would work well for my upstream O2 replacements.  Bosch has been in the automobile parts business for an extremely long time, and I trust them.  One note for the home mechanics, make sure when you pull the old sensors off that the old gasket comes completely off.  If any little pieces are left on the exhaust you will get a reoccurring code fault.  You might be wise to inspect the exhaust mount area for any debris and clean any rust away with a small wire brush.  Any debris may allow external oxygen into the exhaust at the sensor and you will get a exhaust related fault.

My original sensor lasted for around 10 years, mounted outside in all kinds of weather.  I'm hoping this one does the same.  Works great and I paid a good price on Amazon.

Well worth the price!!! A pair for 1/2 the price for one sensor at the other stores. Identical part replacement.

Got this for my 97 4Runner and it was half the price from any other auto-parts store. Denso brand and it works perfectly. Check engine light stays off now.

My daughter's 2002 Honda Accord EX Sedan with a 2.3L SULEV Engine (F23A4) with California Emissions had a glowing "Check Engine" light and was idling very rough and was getting poor gas mileage.  It was showing P1166 and P1167 codes from a scan by the local auto parts store.  I researched the codes and determined that they were likely caused by a malfunctioning upstream Air/Fuel Sensor.  Researched this item extensively to determine that it would likely be a direct replacement for Honda Part 36531-PAA-306.  Bought and installed this Denso 234-9014 sensor (and special socket for sensor removal/replacement), reset the check engine light by pulling and reinserting the "Clock" fuse and the idle smoothed after a couple of miles, gas mileage has improved, no more "Check Engine" light and it has been working flawlessly for over a month.  The best part is that I saved at least $350 versus taking it to the dealer... no kidding!

I got a P0135 on my 96 V6 Camry and went ahead and replaced both the upstream oxygen sensors. Note that the P0135 relates to the upstream sensor on the cylinder bank closest to the firewall. Entire replacement took about five minutes, anyone can do this. Make sure you use the included anti seize. Do yourself a favor and choose a denso oxygen sensor. The piece of mind is well worth it.

I needed some new oxygen sensors for my 2001 prius, and I went on a few websites to compare prices. These were the best priced, and the actual ones my manufacturer used, so it kept the car OEM. My little car was going through some engine light issues, and these seemed to help with that issue. Definitely recommend this to people who need to change these little guys, which usually last around 120K miles. These come with the liquid copper so you don't have rusting in your oxygen sensor area, which results in easy removal whenever you get around to changing them again. I bought both the upper and lower to replace and these worked really well. Made in USA too, which adds to the value. As a longtime Amazon customer, I rely on reviews from the Amazon community when making buying decisions. That being said, I only believe in giving honest and unbiased reviews.[...]
Thanks for reading!

These sensors are great.  I use them with an arduino and a 443mhz receiver to log the data to emoncms.  You cant do better for the price.
