Is your ABS light on in your 2007-2012 Nissan Altima? This pair of front ABS wheel speed sensors might be the solution. They're brand new, unused, and come in their original packaging. This is a complete set for both the left and right front wheels. Fits Altima models from those years including SR, SL, Base, with either the 2.5L or 3.5L engine. The brand is ECCPP, part number ECP818722. Placement is on the front, left and right. They come with a 1-year manufacturer warranty for confidence. Reference part number is 47910-JA000-2, and other part numbers include 5S11191 and \abs sensor front\. Color is black, terminal type is blade. Width is about 5.5cm. The package includes 2 sensors. UPC does not apply. These sensors monitor how fast each wheel is spinning and send data to the ABS computer. If one fails, your ABS and traction control systems may not work properly, and that annoying light stays on. Replacing them in pairs is often recommended, as if one fails, the other isn't far behind. Installation usually involves removing the wheel and unplugging the old sensor. Restore your Altima's safety systems and turn off that dashboard warning. A great DIY repair that can save you a lot compared to a dealer. Drive safely with fully functional ABS!
