Signal Waveform & Data
This example shows a typical Crankshaft Position Sensor (CKPS) and Camshaft Position Sensor (CMPS) waveform at idle (Fig 1). When the 17th signal of the CKPS after missing tooth of the target wheel is aligned with the high signal of the CMPS at idle, PCM recognizes that synchronization between CKPS and CMPS is completed.
