Description
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.

The target wheel consists of 58 slots and 2 missing slots on 360 degrees CA (Crank Angle).
