Oscilloscope Patterns and Waveforms

MAJOR SENSOR REFERENCE WAVE-FORMS
The following are the major sensor reference wave-forms. Below is the data for CMP when rewing quickly up to 4800 rpm under no load after warming up engine sufficiently. Each value is for reference, the exact values may vary.




*CMP AND CKP
Should increase gradually while depressing the accelerator pedal and should decrease gradually after releasing the pedal without any intermittent drop or rise.
