Component Inspection

Component Inspection

1. Set up an oscilloscope as follows :
Channel A (+) : Signal terminal of the CMPS #1 (back probe), (-) : ground
Channel B (+) : Signal terminal of the CKPS (back probe), (-) : ground
2. Start the engine and check for signal waveform compared with reference waveform as below.




1 There are 60 signals of CKPS (Including missing tooth) during the semi-cycle of CMPS #1.
2 There are 3 - 5 signals of CKPS between the switching point of CMPS #1 and the missing tooth of CKPS.








3. Is the signal waveform normal?
