Kia Cee'd: Engine Control System / Crankshaft Position Sensor (CKPS) Description and operation

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.
