Kia Niro 2017 (DE HEV) Service Manual / Engine Control/Fuel System / Engine Control System / Camshaft Position Sensor (CMPS) Repair procedures

Inspection

Check the signal waveform of the CMPS and CKPS using the KDS/GDS.

Specification: Refer to “Wave Form”

Removal

•	Do NOT remove the camshaft position sensor with engine running or right after engine stops due to the possibility of scalding from hot engine oil flowing out.

[Bank 1 / Intake]

1.	Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.	Remove the air cleaner. (Refer to Engine Mechanical System - "Air Cleaner")

3.	Disconnect the camshaft position sensor connector (A).

Remove the camshaft position sensor after loonsening the mounting bolt (B).
