Function 

The front edge of a tooth on the clutch plate generates a positive voltage pulse and the rear edge generates a negative one.

The distance from the positive to the negative voltage peak corresponds to the length of a tooth.

The gap produced by 2 missing teeth results in no voltage being generated in the crankshaft position sensor. This gap is used for detecting the TDC position of cylinder 1.

The distance between the crankshaft position sensor and the teeth of the drive plate is specified by the installation position.
