Hyundai Palisade (LX2): 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. Lack of CKPS signal
may cause the engine to stop. Installed on the cylinder block or the transaxle
housing, it generates alternating current by magnetic flux field made from the
sensor and the target wheel during engine runnig.
The target wheel consists of 58 slots and 2 missing slots on 360 degrees CA
(Crank Angle).

be sure to wear gloves.
Description and operation
Description
The auto defogging sensor is installed on the front window glass. The sensor
judges and sends signal if moisture occurs to blow out wind for defogging. The
air conditioner control module receives a signal from the sensor and restrains
moisture and eliminates defog by the intake actuato
