Review: Retrofitted to a 2002 tundra - Toyota and their dumb 2-bolt sensors. I had this on a 2002 tundra where the old sensor needed replaced and the nuts/studs were rusted in place. Thinking outside the box, I bought this one with the same plug and a band clamp with o2 bung and installed all this beside the old downstream sensor through a hole I drilled in the pipe. Now it has both the old and new sensors next to each other but no more check engine light. Looks weird but it worked well. Ecm reads this one like a new original. Review: 2003 V8 4Runner - I needed this Denso sensor (Toyota uses Denso for OEM) for an engine light that was due to P0430 (Cat efficiency below threshold). This downstream o2 sensor helped fix the issue. It should be noted that on the V6 4Runner this 02 goes on the driver side. On the V8 4Runner the 02 sensor goes on the passenger side (this 02 sensor is for the passenger side because it has a longer wire). After fixing the issue with the engine light if you still have the VSC Trac/Trac OFF lights perform the "zero point calibration". Would recommend to anyone! ## Features - Designed to detect the amount of oxygen in the exhaust system , thread diameter - 18 mm - Constructed from high quality material - Features double protection layer, aluminum oxide trap layer, PTFE filter and stainless steel housing - Manufactured with precision to meet OE standards - Easy installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0016NBBQW | | Best Sellers Rank | #40,173 in Automotive ( See Top 100 in Automotive ) #123 in Car Exhaust Oxygen Sensors | | Brand | Denso | | Brand Name | Denso | | Customer Reviews | 4.5 out of 5 stars 859 Reviews | | Global Trade Identification Number | 00042511112513 | | Included Components | OXYGEN SENSOR | | Item Dimensions | 14.6 x 5.6 x 4.8 centimeters | | Item Type Name | ACCESSORIES | | Item Weight | 0.25 Pounds | | Item dimensions L x W x H | 14.6 x 5.6 x 4.8 centimeters | | Item weight | 0.25 Pounds | | Manufacturer | Denso | | Material | Stainless Steel , Aluminum Oxide | | Material Type | Stainless Steel, Aluminum Oxide | | Measurement Accuracy | ±1.5% | | Measurement accuracy | ±1.5% | | Model | 234-4261 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Output Type | Push-Pull | | Part Number | 234-4261 | | Specific Uses For Product | Oxygen Sensor | | Style | Modern | | Style Name | Modern | | UPC | 042511112513 | | Unit Count | 1 Count | | Upper Temperature Rating | 800 Degrees Celsius | | Warranty Description | LIMITED WARRANTY | ## 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:** Stainless Steel, Aluminum Oxide - **Style:** Modern ## Images ![Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front - Image 1](https://m.media-amazon.com/images/I/513Jm2+RO8L.jpg) ![Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front - Image 2](https://m.media-amazon.com/images/I/51dHLPGL9hL.jpg) ![Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front - Image 3](https://m.media-amazon.com/images/I/41X9oUNBIUL.jpg) ![Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front - Image 4](https://m.media-amazon.com/images/I/31ql7VQnD-L.jpg) ![Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front - Image 5](https://m.media-amazon.com/images/I/5114T2opbSL.jpg) ## Questions & Answers **Q: Is this item work for 2007 Toyota solora 6 cylinders?** A: The Toyota Solara has 2 downstream o2 sensors (and 2 upstream Air Fuel Ratio Sensors). This part ( 234-4261) will fit the front downstream application. The rear downstream sensor is part# 234-4064. You first have to make sure which sensor is bad. Then, If you go to Denso auto parts.com, you can see all the applications for your vehicle before purchasing **Q: Is this the right sensor for Bank 2 Sensor 1 Installation? I think that is front driver side? Thank You** A: This part is for either Bank 1 Sensor 2 or Bank 2 Sensor 2 (the sensor after the catalytic converter). Sensor 1 is the sensor that adjusts the air/fuel mix. It is before the catalytic converter and will likely be a different sensor type. Best to double check first. **Q: Will this fit my toyota tacoma'06 pre runner 4l. engine?** A: I installed on a 2002 4runner. Not sure if it will fit your vehicle. **Q: I own a 2002 4Runner with a sensor that needs the flange; it cannot be separated. Does this come with the flange?** A: I have a 2002 4-runner,it has two oxygen sensors,the one here and also Denso #234-9002 shows it fits this vehicle and it has the flange. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Retrofitted to a 2002 tundra *by O***O on 14 July 2026* Toyota and their dumb 2-bolt sensors.
