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