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...
