Stand-alone, contactless, active sensor providing the position and rotation direction of the crankshaft by reading a ferromagnetic or magnetic encoder wheel mounted on the engine crankshaft.
Output signal used by the Engine Management System (EMS) to determine the absolute engine position required by engine control functions (injection, ignition,…).
Required for stop/start function and misfiring detection, allowing compliance to the emission standards.
