ABSTRACT:
An angular position detector for an internal combustion engine includes a toothed wheel with a missing tooth and a sensor providing a pulse train as the teeth pass the sensor. To provide an accurate datum position signal a micro-computer receives the pulse train and outputs the datum signal when the period between successive pulses is significantly shorter than the preceding period.
