Denso 234-9064 Air Fuel Ratio Sensor with 4-Wire 14” Harness and 0.711” Thread Diameter

The genuine article in the box, assembled in america. Ready to go, easy to install. Connectors fit perfectly (they each have an opposite end so you can't plug in the 2 sensors in the wrong plugs). Functioning perfectly. Comes with threads pre-treated with anti seize compound plus a small tube of extra compound. Do not use more than the smallest amount if you add from the tube. There is enough there to do probably 20 times. There are cheaper units, but this is very high quality and should last a very long time.

Direct fit and works amazing on my 97 Civic

Easy to replace on 2005 honda. The engine light went off

This part went in easily on my 2005 Honda CR-V. Unhooked my battery for the duration of the replacement and after hooking the battery cable back on, my check engine light was off and did not turn back on again. My car is now running great again with previous good gas mileage. I read up on air/fuel (aka oxygen) sensors before I purchased one and read that it is extremely important to buy either an expensive OEM sensor or a Denso brand one. Apparently other manufactured sensors are not wired properly and will not work.

On the pricey side but don’t cheap out and when buying O2 sensors because you will be buying it twice. Worked perfected and check engine light has been off. Passed smog

Easy install.works great. I first tried a cheep one from ebay. Total trash. Engine light came on within 30 seconds of starting car after clearing engine code. Installed this one..have put almost 1000 miles on it, not engine light. Dont waste your time with cheep ones. Get the oem

Installing on my car a few years ago and works just like the original

Great replacement and worked like a charm. Code removed right away and hasn't came back.

Funciona perfectamente, ayudó a mejorar el consumo de combustible y apagó el testigo "check engine".

Around 223,000km on my 2004 Honda Element, I had the check engine light come on due to a faulty primary oxygen sensor (code P0135). You could smell in the car that the oxygen sensor had in fact kicked it. The genuine Honda part was quite expensive and I was looking for an alternative. Some have said that only the genuine Honda sensor would work, but I figured I would give the Denso one a try. Turns out Denso is the company that makes the oxygen sensors for Honda (at least for the Element). It was quite an easy install, having no problems with limited mechanical abilities when it comes to cars. I have a few 1000km on the car with this new sensor, the engine light immediately went away and has stayed off. As well, the unpleasant smell in and around the car has disappeared as well. Great alternative to the genuine Honda sensor and a lot cheaper too!

I liked that it’s easy to install. The check engine light on my dash is gone. It fixed the problem (O2 sensor code-P0161)

P1157 Code ..... aftermarket sensor doesn't work.... got denso check engine light off ....

A bit more pricey, but acceptable.
