Car running rough or giving you check engine lights? Might be your MAP sensor acting up! This X AUTOHAUX replacement MAP sensor is exactly what you need to get your vehicle running smooth again. It directly replaces OEM part number 12681993 and fits a bunch of popular models like Buick Encore (2018-2022), Chevrolet Cruze (2018-2019), Equinox, Malibu, and even those big Silverado and Sierra trucks. The sensor measures intake manifold pressure and helps your engine computer adjust the air-fuel mixture properly - super important for performance and fuel economy. Made from durable ABS plastic with a 4-pin connector, it's built to last and resistant to wear. Installation is pretty straightforward if you're handy, but definitely compare it to your old part first to make sure it matches. Works with both gas and diesel engines depending on the model. Much cheaper than buying from the dealership but does the same job. Keep one in your garage for when that pesky check engine light comes on - your engine (and your wallet) will thank you!
