Crank Position Sensor

The Chevrolet Performance Crank Position Sensor (MPN 12560228) is a crucial component for both high-performance and stock Chevrolet engines, providing the necessary ignition timing reference for optimal fuel injection and spark delivery. This sensor is essential for troubleshooting engine issues, rebuilding classic small-blocks, or enhancing the reliability of LS platforms.

This crankshaft position sensor detects the crankshaft's rotation and sends timing signals to the engine control module (ECM), enabling precise calculations for ignition advance and fuel injection timing. Its compact design (2.3 x 1.55 x 4.1 inches) and lightweight construction (0.08 lbs) allow for easy installation in tight engine bays, while its sealing against oil and coolant ingress ensures durability.

Mechanics and enthusiasts can benefit from this sensor when diagnosing engine performance issues, as it plays a vital role in maintaining synchronization between the crankshaft and ECM. It is compatible with Chevrolet LS and small-block engines, making it a reliable choice for both owner-mechanics and professional shops.
