Camshaft Position Sensor: Description and Operation
The Camshaft Position Sensor
The camshaft position sensor (G signal) consists of a magnet, iron core and pickup coil, and is mounted onto the intake side of the cylinder head.
The timing rotor is integrated with the left bank exhaust camshaft. Each time when the camshaft rotates, the air gap between the camshaft position sensor
and the protrusion integrated onto the camshaft is varied. This causes the magnetic flux passing through the pickup coil to increase and decrease,
generating an electromotive force. Since the voltage is generated when the camshaft protrusion approaches the pickup coil and when it departs, an
alternating electrical current is produced.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34 signals at every engine revolution. The ECM
detects the standard crankshaft angle based on the G signal and the actual crankshaft angle and the engine speed by the NE signal.
