Keep your GM vehicle running smooth with this genuine ACDelco crankshaft position sensor. This is the real deal – an OEM (Original Equipment Manufacturer) part, which means it's exactly what General Motors puts in their cars and trucks at the factory. It's designed to fit perfectly and perform just like the original one you're replacing.
This little sensor is a big deal for your engine. It monitors the crankshaft's position and speed, sending that info to the engine computer (ECM). The ECM uses that data to control fuel injection and ignition timing, which is crucial for power, fuel efficiency, and smooth operation. If yours has failed, you might experience stalling, hard starting, or a check engine light.
Built to the same strict standards and testing as the original, it offers the quality, reliability, and durability you expect. When you need a part that matches GM specs exactly, trust ACDelco. This is the right part to get your engine's timing back on track. Always double-check the part number (12613030) matches your vehicle's requirements.
