Crank Shaft Position Sensor and Camshaft Position Sensor signal are measured simultaneously.
Cam Shaft Position Sensor signal is outputted once when Crank Shaft Position sensor signal is outputtedtwice.
LOW and HIGH output of Cam Shaft Position sensor reference point is detected at Crankshaft Position sensor reference point.
Injection sequence is determined based on LOW and HIGH signal of Cam Shaft Position Sensor reference point as detecting cylinder position.
