Set up an oscilloscope as follows :
Channel A (+): Signal terminal of the CMPS #2(back probe), (-): ground
Channel B (+): Signal terminal of the CKPS(back probe), (-): ground
Start the engine and check for signal waveform compared with reference waveform as below.
A : CMPS and CKPS waveform of exhaust shaft at idle
B : CMPS and CKPS waveform of exhaust cam shaft at acceleration
(Tooth number is changed by CVVT operation)
