Timing Inspection
- 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
- Start the engine and check for signal waveform compared with reference waveform
.
There are 60 signals of CKPS (Including missing tooth) during the semi-cycle of CMPS #1.
There are 3~5 signals of CKPS between the switching point of CMPS #1 and the missing tooth of CKPS.
- Is the signal waveform normal?
YES
- Go to next Inspection procedure
NO
- Repair or readjust as necessary, if air gap of the CKPS is exceeds specification[0.3~1.7 mm (0.012~0.067 in)]. If OK, check that the matching marks on the crankshaft and camshaft pulleys are correctly aligned. Repair or readjust as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
