Hyundai Ioniq (AE) 2017-2022 Service & Repair Manual / Engine Control/Fuel System / Engine Control System / Camshaft Position Sensor (CMPS). Description and operation

Description
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element.
It is related with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which the CKPS can't detect.
The CMPS is installed on engine head cover and uses a target wheel installed on the camshaft. The Cam Position sensor is a hall-effect type sensor. As the target wheel passes the Hall sensor, the magnetic field changes in the sensor. The sensor then switches a signal which creates a square wave.

    Inspection1.Check signal waveform of CKPS and CMPS using a GDS. Specification : Refer to "Waveform"Removal1.Turn ignition switch OFF and disconnect the negative (-) battery cable.

    Signal WaveformThis example shows a typical Crankshaft Position Sensor (CKPS) and Camshaft Position Sensor (CMPS) waveform at idle. The PCM controls the injection and ignition timing by using these signals.
