Denso234-4092 Oxygen Sensor

I only use genuine Denso sensors in Hondas, as they are original equipment. Other brands do not work reliably, especially Bosch.This did not solve my problem, but due to a lot of oil burning (which is now fixed), the sensor needed to be replaced anyway.

I don't know how long it lasts yet ... .

I bought a cheap sensor first then when it didn't work I bought this one. Works perfectly and my fuel trim has normalized.

Denso makes great products! Saves you ton of worries than putting in third party, off-market, no name brand sensors that breaks after a couple of weeks. So far so good on this one.

This sensor really did good job after I replaced downstream oxygen sensor on my 2005 Honda Civic with 102 K miles. Engine light (code P0141) has gone and did not return back after I cleared this code and I week passed.Before I ordered this sensor I checked my old sensor heater's resistance connecting ohmmeter's terminals to pair of contacts belonging to the same color of wires (you have to disconnect this sensor first for this test). In my case both of them were white.I found this circuit was open and respectively my sensor was dead.That's good incentive to start replacement.New sensor I received has 16 ohm resistance .Using previous suggestions I also re-used small rubber boots from old sensor by cutting them along the old cable and placing them on new one under existing holders.What I can't accept is using PVC insulating tape to secure them with cable.I have already had very negative experience when punched/worn rubber vacuum hoses were "fixed" this way in my previous Ford Focus:PVC tape is melting in engine compartment and turns rubber hose taped into jelly.Moreover I received engine light coded PO171 pointing to potential leaks of vac hoses .You'd better use rubber tape used for splicing of electrical wires.Thanks for reading .

Replacing the downstream o2 sensor on my 2005 Honda Civic took about 1/2 hr using the o2 removal socket. The Check Engine Light went out after approximately 100 miles. I drove over 1,000 miles since then and the Check Engine Light has remained off. My only issue was that unlike the original o2 sensor the Denso product did not have rubber sleeves over the wire used to secure the wire away from the fan. I was able to get by using zip ties instead. The Denso 02 sensor got the job done and was a lot cheaper than if I would have bought the equivalent part from Honda.

It is not for 2003 Honda Civic. The connector is not the same

The plug was "plug amd play" into my wire loom. The length of the wire was identical to the original part. One minor draw back. The original had 2 rubber boots along the wire to cushion the metal braxket from wearing into the loom as it holds the loom away from hot and moving parts. To remedy this I simply cut the boots off and slid them onto the new o2 wire loom and secured them with a few twists of electrical tape. Now when I placed the loom into the metal frame holders (2 of them) there is zero chance of them wearing into the wires. This was not really needed but I am a perfectionist when it comes to working on my car. The metal loom holders were loose enough they would probably not cause damage but I need that peace of mind. Stupid O.C.D. Haha

I installed this O2 sensor yesterday. The sensor cleared the engine error code I was getting, so it did its job. The only complaint I have is that the threading on it is not very well done making installing it far more difficult than it needed to be making a 15-20 minute job take far more than that. If the threads were are well defined as the ones on the sensor I removed I would have given it five stars.

Mauvaise piece dans la boite. Ma couter $$$ pour le mécanicien pour rien, ceci ai la faute d’Amazone, la piece étais sence être inspecter pas Amazone..

It perfectly fits to 2001 Honda Civic for the new cat converter. I love the good price also!

It was the right size, except we had to use ties to hold it in the proper place. Happy with the product.

This worked great on my 2005 Civic. It would have been better if it had the protective grommets for the wire but I'm happy with it.
