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. Review: Worked OK in my Honda Accord 2005. ## Features - Efficient Fuel Consumption - Easy installation - Constructed from high quality material - Manufactured with precision to meet OE standards - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00122EEK2 | | Best Sellers Rank | #100,402 in Automotive ( See Top 100 in Automotive ) #318 in Car Exhaust Oxygen Sensors | | Brand Name | Denso | | Customer Reviews | 4.6 4.6 out of 5 stars (942) | | Global Trade Identification Number | 00042511112438 | | Included Components | Oxygen (O2) Sensor | | Item Dimensions | 14.6 x 5.6 x 4.8 centimeters | | Item Type Name | Oxygen Sensor | | Item Weight | 0.25 Pounds | | Manufacturer | Denso | | Material Type | Zirconium Stainless Steel | | Measurement Accuracy | High | | Measuring Range | 0-20% O2 | | Model | 234-4797 | | Mounting Type | Flange Mount | | Output Type | Push-Pull | | Specific Uses For Product | Replacement Oxygen (O2) Sensor | | Style Name | Replacement Part | | UPC | 042511112438 | ## Product Details - **Brand:** Denso - **Item dimensions L x W x H:** 14.6 x 5.6 x 4.8 centimeters - **Item weight:** 113 g - **Material:** Zirconium Stainless Steel - **Style:** Replacement Part ## Images ![234-4797 oxygen sensor - Image 1](https://m.media-amazon.com/images/I/61xnvaj9kfL.jpg) ## Questions & Answers **Q: Will it work on Honda Accord 2007?** A: I purchased this last month and it is no longer working also it is different from the Original, the Original OS had a hole in the middle tip.

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 ### ⭐⭐⭐⭐⭐ Review *by A***T on 27 April 2015* I recently had my catalytic converter replaced on my 2006 4 cyl.

My Accord threw the engine code and this Denso brand O2 sensor has been working fine. Fuel economy has returned to normal and no engine light. You will have to reset your ECU. If you don't know how to do that, I can talk you through it. ## Frequently Bought Together - Denso 234-4797 Oxygen Sensor - Denso 234-9040 Air Fuel Ratio Sensor - Offset Oxygen Sensor Socket, 3/8-Inch Drive, 7/8-Inch (22mm), Wire Gate Accesses Sensor from Side, Preventing Damage to Wires, Universal for Most Cars --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/299396745-234-4797-oxygen-sensor](https://www.desertcart.be/products/299396745-234-4797-oxygen-sensor) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-05*
