Is your tire pressure warning light on because of a dead sensor? This 4-pack of HUNBILFIN TPMS sensors is here to fix it. They're pre-programmed to be direct replacements for a huge list of General Motors vehicles from the 2000s and 2010s, including many Buick, Cadillac, Chevrolet, GMC, Pontiac, and Saturn models (always double-check the full fitment list for your specific car). They match common OEM part numbers like 13581558 and 13598771. These are brand new sensors that operate on the 315MHz frequency. They use a high-quality Freescale chip and a long-life CR2032 battery that's rated to last up to 10 years and can handle extreme temperatures. They've been rigorously tested for durability. Remember, after installation, a shop will need to use a scan tool to \re-learn\ the new sensors to your car's computer. They come with a 1-year warranty. A cost-effective way to get your TPMS system working properly again.
