Review: Worked great and cheap oem - Worked great for my 2006 toyota matrix xr fwd downstream only it means is the one after the catalytic converter,the one before the catalytic is not the same so don't get confused ,you do have to crimp the wires because it doesn't come with the connector to the car but it's pretty easy I made a video on the youtbe if you need help, it comes with the crimp connectors for the wire so you don't have to buy any ,make sure to connect the matching color wires, after I installed the sensor and driving for about 5 miles 3 codes came up but I just erased them with the cheap scanner and they never came back so that means it worked great after 50 miles of installation Review: A Perfect Fit, but Watch the Solder Connections - After a long search this part turned out to be a perfect fit for my Japanese domestic model 2001 Toyota Estima (called the Previa in the USA). Five days after my engine warranty expired my engine check light turned on (go figure). As I'd just bought the car used, and since my salary is low and I'm trying to pay my Japanese bills in yen during the worst dollar/yen exchange rate in history, I decided to search online for a DIY cure. Since the car has an OSDII connector my first thought was to purchase a good middle-quality OSD reader from a USA vendor (they don't sell them here) so I could read the engine code. Such readers are standardized and supposed to work in ALL CARS MADE SINCE 1996, or so said the advertising. When it arrived I tested it, and although the connector is IDENTICAL, the reader kept giving me a "cannot connect" error. After much online searching I found that Japanese domestic cars do not use an OSDII connector, they use a PHYSICALLY IDENTICAL but ELECTRICALLY INCOMPATIBLE DLC3 CONNECTOR (the capitol letters are there to show my annoyance with the car manufacturers for creating "standards" that are anything but). Fortunately the vendor I bought the reader from gave me a refund for all but the return shipping. A kind car mechanic had the correct reader, tested the car for me for free, and gave me the code, P0155. An online search found that it referred to the Bank 2 Sensor 1 O2 sensor heating element. Now came the search for a replacement part, which was an almost as difficult task because there are many available and their prices vary widely depending on whether it comes with an original connector or not. It's very easy to get the wrong one. However, the Denso 234-4209 sensor in this review was a perfect fit for my 2.4L Toyota engine, and the locations for both sensors are just under the hood behind the radiator so getting to them was easy. I bought two at $36 each plus a split socket and a thread-chaser. The Lisle 12100 split-socket is a must, the Lisle 20200 thread-chaser is not, unless you're sloppy with the insertion. Both tools are well made and inexpensive. Two tips: 1) remove the old sensor while the engine is hot (be careful), as it is much easier that way. 2) don't use the crappy crimp-on thingies that come with the sensor, solder the wires instead, but use lots of flux as rosin-core solder alone won't bond to the sensor's very stiff wires. I found that bending the bare wires back into the shape of a fishhook and squeezing them tight with pliers stabilizes the joint long enough to apply the solder. Use the small-diameter heatshrinkable tubing that came in the kit on each joint PLUS a six inch piece of 1/2" heatshrinkable tubing to cover all four bonded and covered wires together. The latter is not absolutely necessary but it makes a tighter cover and it's better than using black tape. Also use the anti-seize compound that comes with the kit - there's enough for at least two sensors in each tube. Total cost for two sensors, tools, and shipping was less than $100, much less than the $300 fee most dealers would have charged to change just one sensor. ## Features - Manufactured to the highest O.E. quality, guaranteed to fit right - Does NOT include the connectors - Aluminum oxide trap, this extra layer helps to protect from silicone and lead poisoning - Stainless steel housing and porous Teflon filter all contribute to make a long life - Improved engine performance and greater fuel efficiency - Prevents premature sensor failure ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C5WCUE | | Best Sellers Rank | #212,313 in Automotive ( See Top 100 in Automotive ) #761 in Automotive Replacement Oxygen Sensors | | Brand | Denso | | Brand Name | Denso | | Customer Reviews | 4.2 out of 5 stars 1,238 Reviews | | Global Trade Identification Number | 00042511142091 | | Included Components | Oxygen (O2) Sensor | | Item Dimensions | 5.75 x 2.19 x 1.88 inches | | Item Type Name | Oxygen Sensor | | Item Weight | 0.25 Pounds | | Item dimensions L x W x H | 5.75 x 2.19 x 1.88 inches | | Manufacturer | Denso | | Material | Stainless Steel, Zirconium | | Material Type | Stainless Steel, Zirconium | | Maximum Supply Voltage | 12 Volts | | Model | 234-4209 | | Mounting Type | Thread-In | | Output Type | electrical signal | | Part Number | 234-4209 | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Replacement Oxygen (O2) Sensor | | Style | Replacement Part | | Style Name | Replacement Part | | UPC | 042511142091 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 800 Degrees Celsius | | Warranty Description | Includes manufacturer provided warranty | ## Product Details - **Brand:** Denso - **Item Weight:** 0.25 Pounds - **Item dimensions L x W x H:** 5.75 x 2.19 x 1.88 inches - **Material:** Stainless Steel, Zirconium - **Style:** Replacement Part ## Images ![Denso Oxygen (O2) Sensor - 234-4209 (Universal Sensor Without Connector) - Image 1](https://m.media-amazon.com/images/I/5167siIg+nL.jpg) ![Denso Oxygen (O2) Sensor - 234-4209 (Universal Sensor Without Connector) - Image 2](https://m.media-amazon.com/images/I/41PQwi1RY3L.jpg) ![Denso Oxygen (O2) Sensor - 234-4209 (Universal Sensor Without Connector) - Image 3](https://m.media-amazon.com/images/I/41qO6vDC5dL.jpg) ![Denso Oxygen (O2) Sensor - 234-4209 (Universal Sensor Without Connector) - Image 4](https://m.media-amazon.com/images/I/31wN8DPS8+L.jpg) ![Denso Oxygen (O2) Sensor - 234-4209 (Universal Sensor Without Connector) - Image 5](https://m.media-amazon.com/images/I/51Ki7AjPsEL.jpg) ## Questions & Answers **Q: will Denso 234-4209 Oxygen Sensor work for Toyota sienna** A: Amazon allows for a car's make, model, year, etc. to be entered at its site to find out if a particular part will fit that car or not. Please do so to find out if Denso 234-4209 oxygen sensor will fit your car. **Q: It does come with a connecter? So I'm buying what exactly?** A: You have to cut the connector off the old part & splice the wires to the new O2 sensor. Part comes with wire crimp fittings. **Q: Is this for upstream or downstream?** A: To answer your question correctly I would have to know the vehicle year, make, model to complete your request. Most O2 sensors are for the front or back with the wiring connector being different, so if you do not find a match by running your vehicle off the Amazon site call Auto-Zone or look on their site to confirm the correct number for the sensor. I will warn you that using any aftermarket sensor is not the same as OEM which means the milliamp output is not the same by the aftermarket part and may not clear the code in your vehicle. **Q: What is the heating coil resistance? I installed on the car and got check engine code. Measure the heater resistance 29Ohms, that seems too high.** A: It is a bad reading on your part, or the sensor is bad ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great and cheap oem *by L***. on March 11, 2024* Worked great for my 2006 toyota matrix xr fwd downstream only it means is the one after the catalytic converter,the one before the catalytic is not the same so don't get confused ,you do have to crimp the wires because it doesn't come with the connector to the car but it's pretty easy I made a video on the youtbe if you need help, it comes with the crimp connectors for the wire so you don't have to buy any ,make sure to connect the matching color wires, after I installed the sensor and driving for about 5 miles 3 codes came up but I just erased them with the cheap scanner and they never came back so that means it worked great after 50 miles of installation ### ⭐⭐⭐⭐⭐ A Perfect Fit, but Watch the Solder Connections *by N***T on September 22, 2012* After a long search this part turned out to be a perfect fit for my Japanese domestic model 2001 Toyota Estima (called the Previa in the USA).

I've concluded it's worth the extra money to purchase OEM Denso sensors, and this one hasn't disappointed - working well. That said, I was surprised to discover that the four wire colors of this replacement unit were totally different than the original factory wiring. Which is the signal wire? Which the ground? are the two black wires the same as the two white ones?? and so on.... The instructions are silent about this. So... Fortunately, after some serious searching the Toyota forums, I found a post listing the colors. So I’ll include it here, in case you have the same experience: Denso ------------------- OEM wiring Blue ------------------- Black Signal + White ------------------- Gray Signal - Black ------------------ White heater Black ------------------ White heater You are supplied with crimp connectors, waterproofing shrink wrap sleeves, and anti-sieze compound. Cut the old wires off at the sensor, strip 1/4" off each wire end, slip the respective wires into connectors and crimp (need a crimping tool), slide the heat sensitive shrink wrap sleeves over each connection and heat until they shrink and seal the connection. I gave four stars instead of five because of the wiring color differences. ## Frequently Bought Together - Denso 234-4209 Universal Oxygen Sensor with 11.5” 4-Wire Harness (connectors not included) - 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 - Denso 234-4011 Oxygen Sensor --- ## 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.tw/products/1911515-denso-oxygen-o2-sensor-234-4209-universal-sensor-without-connector](https://www.desertcart.tw/products/1911515-denso-oxygen-o2-sensor-234-4209-universal-sensor-without-connector) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-20*
