  1. CONSTRUCTION


    1. A Hall IC type crankshaft position sensor is used.

    2. The multi-pole sensor wheel has 58 magnetic pole pairs and a reference point. The reference point is a magnetic pole pair that is two times longer than the other magnetic pole pairs. TDC is detected using this reference point.

    3. The transition from a high to a low phase is signaled by a change in the magnetic field. The difference between 2 changes of the magnetic field is 6° crankshaft angle.
