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).
