Crankshaft Position
Sensor (CKPS) detects the crankshaft position and is one of the most
important sensors of the engine control system. If there is no CKPS signal
input, the engine may stop because of CKPS signal missing.
This sensor is
installed in ladder frame and generates alternating current by magnetic
flux field which is made by the sensor and the target wheel when the
engine rotates. The target wheel consists of 58 slots and 2 missing slots
on 360 CA (Crank Angle). In case of ISG, the ISG function get reliable
information about crank shaft position during all modes of operation. The
CKPS in ISG function ensures short restarting time for engine and
efficient combustion.


Two separate
differential channels for speed and direction information
respectively.
Phase separation of
the 2 channels delivers information on rotation direction.
