Answer 1It is a sensing device which detects each revolution of the crankshaft, and the rotational position of the crankshaft at any given time, in order to provide that information to the engine computer.

The computer then uses that information as a reference upon which to base ignition timing adjustments.

It reads the position and/or speed of an engine as it is rotating.
