Denso Oxygen (O2) Sensor - 234-4797 (Fits 2004-2008 Acura TSX and 2003-2007 Honda Accord Vehicles)

It worked even fixed the check engine light, I thought I had to change the catalyst converter or buy another. It was perfect fit and helped my car efficiency, it even went in perfectly I thought replacement was gonna be a pain but it wasn’t.

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.

I installed this on my 2007 Accord 2.4 49 state (non-CA) car. Works perfectly. Easy to install.Denso makes the OEM Honda sensor but this one is made by Denso's aftermarket division. The sensor is almost the same but it's not identical. The hole pattern in the sensor itself is different but I don't think that will affect its function.The wire is missing the rubber sleeves that clip into the plastic wire brackets on the car. This makes the wire loose and easy to come out. My recommendation is to line up the old wire with the new wire and wrap some extra electrical tape around the locations where the rubber sleeves are located. This will thicken up the wire so that it fits snugly on the wire bracket.

Direct fit, cleared code it has been off now for months

Lowest price on this OEM Honda part. My buddy passed smog in California after I replaced this sensor.Fyi the zone and their green competition sell it for about 80.Make sure you heat the original up real nice otherwise it isn't coming out. Ask me how I know.

I did much research on this.On my 03 accord I was getting "check engine" light. Checked the code with OBD reader it was PO141 which is Secondary Heated Oxygen Sensor (sensor 2).The consensus in different Honda forums is the after market sensors from your local auto parts franchise don't last. So with that said, the price from local Honda dealer was about $115 or online from dealers that sell discounted over the internet was about $80 with shipping.In pricing this part I found that Denso is supplier to Honda for this part. The part I took off my Accord (original part from factory) even has Denso name on it.I figured if I was paying for a Denso part from a Honda dealer I would buy it from Amazon for at the time [...]I can report that it was a perfect fit. It does come with the rubber grommet on the wiring harness for the floor board, just as the Honda OE part.It has been on the car a little over a month and everything is good, no "check engine" light.If the part fails in future I will try to update this review.Hope this helps someone.
