My truck has 3 oxygen sensors, and one after the CAT went bad causing rough idle and increased fuel consumption. Also, the engine light would come on almost everyday, after I clear the code. All 3 oxygen sensors are the exact same on these trucks, so if you have a 1998-2005 s10 with the 4.3 vortec, or a 1998-2005 Blazer with the 4.3 Vortec, this oxygen sensor will work, and you can buy three of these to change all the oxygen sensors. I decided to go with these Denso oxygen sensors because Denso is reputable, and makes great OEM parts that fit and function just like OEM. I have never had issues with Denso parts, ever. These oxygen sensors also came with graphite anti-seize already applied to the threads, which is nice, but copper would have been a better choice for exhaust components. I just needed one oxygen sensor, but decided to just replace all 3, since the original ones were all 24 years old. Took me 30 minutes to replace. My truck now runs and idles much smoother, and based on the scan tool reading, it seems these o2 sensors work just like it should! ## Features - Designed to detect the amount of oxygen in the exhaust system - Constructed from high quality material.Connector Gender: Male - 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 | B000C5UFJE | | Best Sellers Rank | #65,845 in Automotive ( See Top 100 in Automotive ) #158 in Car Exhaust Oxygen Sensors | | Brand Name | Denso | | Country Of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (881) | | Global Trade Identification Number | 00042511140127 | | Included Components | Oxygen Sensor | | Item Dimensions | 14.6 x 5.6 x 4.8 centimeters | | Item Type Name | Oxygen Sensor | | Item Weight | 113 g | | Manufacturer | Denso | | Material Type | High Quality Material, Stainless Steel | | Maximum Supply Voltage | 4.9 Volts | | Measurement Accuracy | Β±1% | | Model | 234-4012 | | Mounting Type | Threaded | | Output Type | analog | | Specific Uses For Product | Oxygen Sensor | | Style Name | Modern | | UPC | 042511140127 | ## 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:** High Quality Material, Stainless Steel - **Style:** Modern ## Images ![Denso 234-4012 Oxygen Sensor, Original Version - Image 1](https://m.media-amazon.com/images/I/41AuIeCciJL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: will denso 234-4012 replace my 2010 sentra sensor????** A: If the number match they will **Q: Will these go on 2005 gmc yukon 5.3** A: maybe.dont waste your money or your time installing them once I bought were dead within 6 months I don't know if cheap Chinese has a rip off but maybe it's Korean? **Q: Le queda a un Izuzu Rodeo 2003** A: No sirve **Q: Does this o2 sensor come with the plug for direct hook up?** A: Yes, on my 95 LT1 was plug and play. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***G on 4 September 2019* Denso siempre la mejor calidad ### ⭐⭐⭐⭐⭐ Review *by S***Y on 20 April 2025* I needed oxygen sensors for my 2001 Chevy Blazer.
