If your check engine light is on or you're having engine performance issues, it might be the camshaft position sensor. This aftermarket sensor is designed to replace OEM part numbers like 12577245, 917-720, and several others. It's compatible with a range of GM vehicles from about 2006 to 2017, including models like the Chevrolet Equinox, GMC Terrain, Buick LaCrosse, and more—always double-check your specific year and model before ordering.
The sensor provides real-time data on camshaft rotation and position to the ECU, helping with ignition timing and fuel injection. This is a brand-new part, sold as a single sensor. Installation is straightforward if you're familiar with basic auto repair, but consult a professional if unsure. A reliable, affordable replacement to get your engine running smoothly again.
