Trigger Wheel for Crank Position and Engine Speed:
Use a trigger wheel with a good finish quality, preferably the original engine trigger wheel.
Important comments:
Use a trigger wheel with teeth width at least one and a half times the width of the sensor pole, so as the
distance between the teeth, which should be symmetrical. The missing teeth width of the trigger wheel should be at
least one and a half times the size of the tooth, that is, 2.25 times the size of the pole of the sensor. Also note that
the distance between the sensor and the trigger wheel should be between 0.6 mm and 1 mm. In general, most of
sensors require a distance of 0.8 mm for the trigger wheel.
