Worked instantly and the check engine light turned off. Changing it out does require a special socket, but you can rent them from AutoZone if you don't want to purchase it. The mechanic quoted me about $350 to change this out, and took me 20 minutes after finding the part here on desertcart. Review: Works like it should... - I tried some off ebay and while the unit worked, the Fuel Air module did not. Tried two from that seller... This was what was actually needed. It is both a Fuel/Air and Oxygen sensor as required by my vehicle - a 2006 Toyota Highlander. With the right tool, change out is quite simple. Without it... what a pain in the ..... Any way, if this is what you need, This is a good buy. ## Features - Improve fuel economy - Lower emissions - Made from durable material - 100% OE based oxygen sensor - Easy installation - Fit type: Vehicle Specific - Designed to determine the oxygen content of the exhaust gas - Improves fuel economy and lowers emission - Facilitate easy installation - Corrosion resistant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C8ZJN8 | | Best Sellers Rank | #2,140,307 in Automotive ( See Top 100 in Automotive ) #12,181 in Automotive Replacement Oxygen Sensors | | Brand Name | Walker Products | | Customer Reviews | 4.2 4.2 out of 5 stars (39) | | Global Trade Identification Number | 00724620043963 | | Included Components | Sensor^Anti-Seize Compound^Instruction Sheet | | Item Dimensions | 5.75 x 1.85 x 2.13 inches | | Item Type Name | Oxygen Sensor, (4-W Air Fuel Ratio) | | Item Weight | 3.63 ounces | | Manufacturer | Walker Products | | Material Type | Stainless Steel | | Measurement Accuracy | 12.5 - 18.0% | | Measuring Range | 12.5 - 18.0 | | Model | 250-54007 | | Mounting Type | Flange Mount | | Output Type | electrical signal | | Specific Uses For Product | Oxygen Sensor | | Style Name | Durable | | UPC | 724620043963 | | Unit Count | 1.0 Count | | Warranty Description | 90 Day Warranty | ## Product Details - **Brand:** Walker Products - **Item Weight:** 3.63 ounces - **Item dimensions L x W x H:** 5.75 x 1.85 x 2.13 inches - **Material:** Stainless Steel - **Style:** Durable ## Images ![Walker Products 250-54007 4-Wire Air/Fuel Ratio Sensor - Image 1](https://m.media-amazon.com/images/I/612PFjzEP0L.jpg) ![Walker Products 250-54007 4-Wire Air/Fuel Ratio Sensor - Image 2](https://m.media-amazon.com/images/I/61hmVFCQ3yL.jpg) ![Walker Products 250-54007 4-Wire Air/Fuel Ratio Sensor - Image 3](https://m.media-amazon.com/images/I/61TjHk7l2lL.jpg) ![Walker Products 250-54007 4-Wire Air/Fuel Ratio Sensor - Image 4](https://m.media-amazon.com/images/I/61obSAchl-L.jpg) ![Walker Products 250-54007 4-Wire Air/Fuel Ratio Sensor - Image 5](https://m.media-amazon.com/images/I/61bpHn2nloL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great, easy fix for much cheaper than dealer *by D***N on July 5, 2013* 06 Scion TC, upper oxygen sensor replacement.
