This is a brand new MAP (Manifold Air Pressure) sensor that fits a range of GM vehicles including Buick, Chevrolet, Oldsmobile, Pontiac, Cadillac, and GMC models. The main OEM part number is 12569240, but it also replaces several others like 17112715, 16137039, and more—check the list in the description to be sure. It’s made by HONGWIN, comes with a 1-year manufacturer warranty, and is built to OE specs. The sensor has a single wire connector, is finished in new condition, and is manufactured in China. It’s a direct plug-and-play replacement, so no reprogramming is needed—just swap it out if your engine is running rough, throwing a code, or has poor fuel economy. Reliable, affordable, and easy to install. Perfect for DIY mechanics or shops looking for a quality aftermarket sensor that won’t break the bank.
