I will say that I installed and have been driving with this sensor for over a year now with no issues. When my Lancer's check engine light came on, the first shop I went to was all booked up but offered to read the code for me. It was the O2 sensor. I shopped around and was quoted anywhere from $130-$400 to replace it. For $80 on desertcart I was able to buy this, an ODB II reader which I can continue to use for future repairs, and the proper wrench to do the repair myself. I spent 10 minutes watching a tutorial on YouTube and about a half hour performing the repair. The old sensor was burnt and visibly worn, and the part number was different from the OEM part (although still Denso) but it fit perfectly and performs as expected. I'm the farthest thing from a mechanic, but this is one of those easy repairs that will save you a ton of cash. I highly recommend doing so if you're on the fence about it. Review: diagnosis was the upstream O2 sensor was bad. Ordered this - Check engine light was on, diagnosis was the upstream O2 sensor was bad. Ordered this, shipping was super fast and awesome. Old part was out and this one was in in less than 10 minutes. Driving it around for about a day got the check engine light to go out and the car passed inspection! You will want to buy the special socket for replacing O2 sensors. It's basically a deepwell socket with a slot in one side so you can slide it down onto the part with the wire through the slot. I tried to remove the old one from the car using just a wrench but there was not enough room. Mechanics wanted $150 to do this job - don't let them. You can do this. ## Features - Designed to detect the amount of oxygen in the exhaust system - 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 | B000C5SGE0 | | Best Sellers Rank | #1,187,095 in Automotive ( See Top 100 in Automotive ) #6,818 in Automotive Replacement Oxygen Sensors | | Brand | Denso | | Brand Name | Denso | | Customer Reviews | 4.7 out of 5 stars 100 Reviews | | Global Trade Identification Number | 00042511110908 | | Included Components | OXYGEN SENSOR | | Item Type Name | ACCESSORIES | | Manufacturer | Denso | | Material | Zirconium | | Material Type | Zirconium | | Measurement Accuracy | Β±1.5% | | Model | 234-4739 | | Mounting Type | Threaded | | Output Type | Digital | | Part Number | 234-4739 | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Oxygen Sensor | | Style | Modern | | Style Name | Modern | | UPC | 042511110908 | | Unit Count | 1.0 Count | | Warranty Description | Includes manufacturer provided warranty | ## Product Details - **Brand:** Denso - **Material:** Zirconium - **Measurement Accuracy:** Β±1.5% - **Mounting Type:** Threaded - **Style:** Modern ## Images ![Denso 234-4739 Oxygen Sensor - Image 1](https://m.media-amazon.com/images/I/41tvx38bgCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ but this is one of those easy repairs that will save you a ton of cash *by T***A on June 19, 2015* Disclaimer: I'm not a mechanic, so this review turned out to be more about my experience in replacing an O2 sensor for the first time than the product itself.

The cable needed 3 or 4 more inches of length to be able to mount harness connector mount. My original cable was 14” long and this one was not. --- ## 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.ph/products/13893268-denso-234-4739-oxygen-sensor](https://www.desertcart.ph/products/13893268-denso-234-4739-oxygen-sensor) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-13*
