Abstract
An apparatus for sensing engine speed and engine angular position. A tone wheel with a plurality of reference indicators and a position indicator is mounted to a camshaft gear. The reference and position indicators rotate past a Hall effect sensor which generates a sensor signal suitable for use by a controller for determination of engine speed and engine angular position.
