Crankshaft Position Sensor: Description and Operation

CRANKSHAFT POSITION SENSOR DESCRIPTION AND OPERATION

NE SIGNAL

The crankshaft position sensor (NE signal) consists of a signal plate and a pick up coil. The NE signal plate has 24 teeth and is built into the distributor.
When the camshaft rotates, the protrusion on the signal plate 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 sensor generates 24 signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G1, G2 signals, detects the actual crankshaft angle and the engine speed by the NE signals, and detects misfire by NE2 signals.

NE2 SIGNAL

The crankshaft position sensor (NE2 signal) consists of a signal plate and a pick up coil.
The NE2 signal plate has 34 teeth and is mounted on the crankshaft. When the crankshaft rotates, the protrusion on the signal plate 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 NE2 signal sensor generates 34 signals for every engine revolution. The ECM detects the standard crankshaft angle based on G1, G2 signals, detects the actual crankshaft angle and the engine speed by NE signals, and detects misfire by NE2 signals.
