Hyundai Santa Fe (TM): 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 on the cylinder block or the transaxle housing and generates alternating
current by magnetic flux field which is made by the sensor and the target wheel
when engine runs.
The target wheel consists of 58 slots and 2 missing slots on 360 degrees CA
(Crank Angle).
