Abstract
Internal combustion engine camshaft phaser position detection with a single position sensor fixed in position relative to a rotatably driven member rotating in constant phase with the engine camshaft and a rotatably driving member rotating in constant phase with the engine crankshaft. Teeth or slots are provided on the driven and driving members and pass in proximity to the sensor for varying a sensor output signal which is processed to determine the relative time of passage of the driving and driven members to determine relative phase therebetween.
