Hyundai Ioniq (AE): Engine Control System / Camshaft Position Sensor (CMPS). Troubleshooting

Signal Waveform

This 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.
Generally CKPS signal is used to detect the piston's position and CMPS signal is used to detect the Top Dead Center of each cylinder.

    DescriptionCamshaft 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.
