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).
