Timing Inspection

With ignition "OFF", set up an oscilloscope as follows :
Channel A (+): terminal 3 of the Crankshaft Position Sensor (CKPS), (-): ground

Channel B (+): terminal 3 of the Camshaft Position Sensor (CMPS), (-): ground
Start the engine and check for signal waveform whether synchronize with camshaft sensor or not.

Fig 1: Signal Waveform Of CMPS Falling Rising Edge Of CKP
Is the signal waveform normal?
YES
- Go to next step as below.
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 crankshaft and camshaft are correctly aligned the matching marks of the pulleys. Repair or readjust as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
