Kia Cadenza YG 2016-2021 Service Manual / Engine Control / Fuel System / Engine Control System / Crankshaft Position Sensor (CKPS) Description and Operation
| 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 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).
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the ECTS connector. 3. Remove the ECTS (Refer to "Removal"). 4. After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 3 and 4.
