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.
