Review: Perfect fit for accord - Perfect replacement on 2003 accord. No more check engine light. Get slotted socket to remove and replace and spray old sensor with penetrating oil before trying to remove.
Review: For a 2006 Honda Accord - Good deal! - I recently had my catalytic converter replaced on my 2006 4 cyl. Honda Accord and they recommended I fix the o2 sensor that plugs into the converter. I found it here and purchased based on the reviews. Upon receiving, I opened it to find the sensor, anti-seize lube, and directions. After I removed the old o2 sensor, I compared them side-by-side and found them to not be identical. Mainly, the wiring cover is not as thick as the old one. It doesn't snap into the clips that hold it in place. The tip of the sensor on the new one also has more holes (which may be a good thing). With that being said, you can still place the wiring onto the clips, and because they are facing up, it shouldn't be a problem. And since I've only owned this car a few months, I have no way of knowing if the old one was a OEM part or if Denso just makes them differently now. Either way, I feel comfortable installing based on the reviews here. The installation itself went fairly smoothly. Before you begin, make sure to purchase here or rent the o2 sensor socket set at AutoZone because you will need them. The only one in the set that fit in the space was the Powerbuilt 648691 Oxygen Sensor Offset Puller. Also, make sure your wrench is long enough because you will need the leverage to get the old one off. And when you need to get under the passenger seat, just unbolt the seat and tilt it back. It's a lot easier and more accessible than trying to maneuver underneath the seat in a tight space. There was more than enough anti-seize and everything screwed/clicked into place just fine. My check engine light was not on for the sensor, but everything is running good so I can say as of right now that this was a great and affordable buy. If anything changes in the next year or so I'll be sure to update. If you are on the fence on doing it yourself, just look up a couple YouTube videos and follow the tips from the reviews here and you'll be fine. This was my first time and it was a lot easier than I expected.

### ⭐⭐⭐⭐⭐ This sensor worked in 05 Accord, and was able to clear code where other new cheap one failed.
*by C***S on October 29, 2025*

Follow my shrthnd. Had Cat cvtr rust out at the rear flange. So plan was to replace cat, and the O2 as well in case old O2 was stubbrn. Ordrd cheap o2 and got what I payed for - Engine code (P401) that would not clr. Had to order this Denso so 05 Accord wouldn't thro code. Had to roll around underneath on my back again bec I tried to save a buck. This sensor worked in 05 Accord, and was able to clear code where other new cheap one failed. On the positive side I was able to cut the rubber surrounds that go into the clips underneath car from the cheap O2 sens that didn't work and use them on the DENSO because it didn't come w/ them.
