Hyundai Santa Cruz: Engine Control System / Crankshaft Position Sensor (CKPS)

- 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. This sensor is installed on 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).

1.Check the signal waveform of the CMPS and CKPS using the diagnostic tool.
