Abstract
A method and apparatus for detecting an engine crankshaft angular position which provides for fast starting of the engine. A target wheel and sensor combination generate an analog signal which is convened into a 24 bit digital output which repeats every 360.degree. rotation of the crankshaft. Each bit represents a particular angular position of the crankshaft. Any 6 sequential bits in the repeating 24 bit digital output sequence form a unique pattern. By monitoring the first six bits generated (90.degree. of crankshaft rotation) during startup, a crankshaft angular position can be determined, thereby enabling fast starting of the engine.
