Camshaft Position Sensor: Description and Operation

The camshaft position sensor which detects the crankshaft angle signal (G signal), has been installed on the front of right bank cylinder head. The timing rotor has been integrated with the right bank camshaft timing pulley When the camshafts rotate, the protrusion on the timing rotor and the air gap on the pick up coil change, causing fluctuations, in the magnetic field and generating an electromotive force in the pick up coil. The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34 signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft angle and the engine speed by the NE signals.
