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)
