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.

I have a 2006 4 Door Accord Exl 4CYL SULEV. THIS IS NOT THE CORRECT PART!!! **Q: can this be use as the up stream o2 too?** A: the upstream Oxygen sensor for a 2003 Honda Accord EX/4 door/4 cylinder is Denso part#: 234-9040. the Denso 234-4797 Oxygen Sensor is the downstream sensor. Not interchangeable. **Q: Will fit on honda ccord 2004?** A: it did perfectly for Accord EXL 2006. **Q: How many wires are on this unit. Toyota has 3 on the downstream** A: don't know, it was a perfect fit, just plug it in ## Customer Reviews ### ⭐⭐⭐⭐⭐ For a 2006 Honda Accord - Good deal! *by A***T on April 27, 2015* I recently had my catalytic converter replaced on my 2006 4 cyl.

I bought the special wrench Powerbuilt 648442 1/2" Wrench and 7/8" Drive Oxygen Sensor Sockets and had no trouble removing the old sensor. I did spray Gunk L106 Liquid Wrench Penetrating Oil on the sensor which is located on the right side of the catalytic converter the night before I removed the sensor and the next morning it came out with little struggle. This part is an exact fit - grommet and all. It is connected by a plug which is located under the passenger seat which has to be removed but it is held in place by 4 bolts, 2 in front and 2 behind the seat so the job is easy with a socket wrench. It even comes with anti-seize compound which you sparingly put on the threads of the sensor ONLY. Then you insert the new sensor into the catalytic converter and twist it in by hand allowing the wire to rotate freely so it doesn't twist as you turn the sensor. Then tighten it with the slotted socket taking care to seat it properly over the sensor before tightening. After that you place the wire back into the two wire clips that keep it away from the heat shield and slide the grommet sideways into the hole under the seat where the other grommet was and then pop it into place in the floor, re-install the seat with the 4 bolts and you're almost done. To reset the "check engine" warning light you need to disconnect the negative battery terminal for a few moments but remember that you will need the security code for your radio once you reconnect the battery. When you turn the radio back on, it will say "cOdE" and if you still have the card that came with your card or if the sticker with the code is still in your glove box (usually on the left side of the door)just enter the five digit number and you're set. If you can not find it your Honda service department can provide it but you will need the serial number of your radio which you can locate by pressing the 1 and 6 button on your radio simultaneously and the serial# will appear on the display with the first five numbers (it will say upper)followed by the second five numbers (it will say lower) - write it down. You provide this ten number serial number to the dealer and they can give you the proper code for your radio which you input using the six numbered buttons on the radio for preset stations and cd's. If you did everything correctly, the check engine light should now be off and stay off unless of course there is another code you need to attend to and the radio should work just fine.
