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.

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

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.

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

Exact fit in 2006 Honda CRV. Connector was the same as the original, unlike some generic sensors that need to re-use the old connector. Includes a little tube of anti-seize. Compare to a Honda branded part with an MSRP of $300, discounted to $215. You can probably find a cheaper one, but Denso is the OEM for most of these kind of things on Japanese cars. BE ADVISED - this is the front A/F sensor, sometimes called the primary O2 sensor. This is probably the one that failed (read the codes). I pulled them both out and looked at them. The front and back sensor are NOT the same. Some people have gotten away with generics on the back, but not the front. So this will probably cost you $400 at the dealer ($300 part and $100 labor) or you can buy this and the O2 sensor socket and DIY in about 10 minutes.

After losing my catalytic converter in my Element to thieves, I bought a cheap cat here on Amazon and some cheap sensors. The catalytic converter works pretty well, but the sensors failed after a month, setting off the check engine light, and my fuel economy dropped to 16 mpg. I limped along like that for a while, then sprung for the oficial Denso sensors, and saw an immediate change. Where the old sensors had been reading that the mix was lean (and hence causing more fuel to be injected, resulting in poor mileage), the Denso sensor appears to be spot-on. Mileage is back to the normal lackluster 24-ish mpg the Element is known for. Well worth the extra $$.

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)

This was a direct replacement for the upstream O2 sensor on our 2007 Honda Element that had the engine light on and the code for the heater circuit coming up on the OBD II. Installed and started the engine light was out. great deal!

A bit more pricey, but acceptable.
