Oscilloscope Patterns and Waveforms

MAJOR SENSOR REFERENCE WAVE-FORMS
The followings are the major sensor reference wave-forms. Below is the data for Rear O(2) Sensor, Front O(2) Sensor when revving quickly up to 4800 rpm under no load after warming up engine sufficiently. Each value is for reference, the exact values may vary.




* FR O(2) SENSOR and RR O(2) SENSOR
FR O(2) and RR O(2) sensor may increase immediately after depressing the accelerator pedal and may decrease after releasing the pedal.
