Oscilloscope Patterns and Waveforms

MAJOR SENSOR REFERENCE WAVE-FORMS
The followings are the major sensor reference wave-forms. Below is the data for Rear O2 Sensor, Front O2 Sensor and Injection Pulse 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 O2 SENSOR and RR O2 SENSOR
FR O2 and RR O2 sensor may increase immediately after depressing the accelerator pedal and may decrease after releasing the pedal.
