Pretty easy to replace with just metric ratchet set, metric wrench and mallet. Hardest part was getting the old one off. Tried PB Blaster, but not sure that helped. Tried running the engine for awhile to get it nice and hot (be careful under there when it is hot, easy to get a nasty burn). I think the heat may have helped along with a mallet to pound on the wrench handle. Either that or just persistence. Comes with a bit of anti-seize compound. All the attachment clips fit exactly which is great because these are always a bear to get off without breaking. In this case can just cut and grab without having to try and save them. Highly recommended to fix this sensor code. Review: This sensor was exact fit for my 2006 Lexus RX330, its been working perfect for several months months now. Definitely recommend. ## Features - Fit type: Universal Fit - Efficient Fuel Consumption - Constructed from high quality material - Designed to detect the amount of oxygen in the exhaust system ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0018JVJB6 | | Best Sellers Rank | #115,053 in Automotive ( See Top 100 in Automotive ) #412 in Car Exhaust Oxygen Sensors | | Brand | Denso | | Customer Reviews | 4.6 4.6 out of 5 stars (278) | | Date First Available | 1 January 2024 | | Exterior | Machined | | Item Weight | 113 g | | Item model number | 234-4509 | | Manufacturer | DENSO | | Manufacturer Part Number | 234-4509 | | Model | 234-4509 | | Product Dimensions | 14.61 x 9.86 x 5.56 cm; 113.4 g | ## Product Details - **Brand:** Denso - **Item dimensions L x W x H:** 14.6 x 9.9 x 5.6 centimeters - **Item weight:** 113 g - **Material:** Zirconium Stainless Steel - **Style:** Replacement Part ## Images ![Denso 234-4509 Heated 4-Wire Oxygen Sensor with 25.5” Harness for 2004-2016 Lexus/Toyota V6 Right-Bank Downstream - Image 1](https://m.media-amazon.com/images/I/51hKYkf6-rL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by I***R on 30 September 2017* Resolved the computer code and Service Engine Light.

Definitely recommend. ### ⭐⭐⭐⭐⭐ Review *by H***G on 25 December 2021* It came in different Denso Part # on the unit. May be new update from Denso. But it fixed our 2004 Lexus RX330 code P420 Bank 1 (by fire wall side). Don't change the cat converter first, change this first! ## Frequently Bought Together - Denso 234-4509 Heated 4-Wire Oxygen Sensor with 25.5” Harness for 2004-2016 Lexus/Toyota V6 Right-Bank Downstream - Denso 234-4168 Downstream Oxygen Sensor with 4-Wire 13.7” Harness - Denso 234-9042 Air Fuel Ratio Sensor --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/350243371-denso-234-4509-heated-4-wire-oxygen-sensor-with-25](https://www.desertcart.id/products/350243371-denso-234-4509-heated-4-wire-oxygen-sensor-with-25) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-06*
