Individual Operation

Crankshaft position sensor 2 consists of a permanent magnet and Hall IC. When the engine is running, the gap between ring gear and crankshaft position sensor 2 is changed by the gear teeth. The changing gap causes the magnetic field near the sensor to change. Due to the changing magnetic field, the voltage from the sensor changes. Detailed piston position can be detected by reading this because the ring gear includes more teeth than the signal plate detected by crank shaft position sensor 1.
