The Camshaft and Crankshaft Position Sensors provide data to the PCM which controls the spark timing and ignition … A category of position sensors, rotary position sensors can measure rotational angles from output voltages. The optical position sensors are an essential component in self-driving cars. Since there is no contact between the sensors and sensed object and lack of mechanical parts, these sensors have long functional life and high reliability. One common device is a resistive position sensor … Also, when the sensor’s power fails, some retain the measured position data, and other types lose the information. Position sensors are concerned with the determination of the position of some object with rereference to some reference point Proximity sensors are a form of position sensors.
