Stage 1: Car was OFF
Stage 2: Press IGN on to READY directly, with foot on brake, transmission set to D
Stage 3: Brake slightly released
Stage 4: READY, D, Brake fully released but accelerator not pressed (tires were coasting). (Green ECO light was ON)
Thanks for clarification!
Judging by the way the pulse repetition period changes in state 3, it is quite likely that the rotor is already rotating in this state.
Recommendations regarding this case of using an oscilloscope.
a) reduce the sweep time to 5 ms per division;
b) set the sensitivity to 1 V per division for both channels;
c) (optional) since one of the outputs has a constant component (approximately >2 V), then "close" the input so that the oscilloscope displays alternating signals (the icon of this mode is in an orange outline).
My confusion.* I cannot understand why the signals are so different in shape. One of them resembles the output signal of an inductive sensor (pseudo sine wave), and the other is similar to the output of a digital sensor (rectangle).

It's a pity that the oscilloscope is not protected from interference with a frequency of 100 Hz.
What is your AC frequency, 50 Hz or 60 Hz?
* UPD. Apparently this drawing removes almost all questions about the forms of signals of the rotor rotation sensor
Thanks to this post,
https://www.myrav4ev.com/threads/speed-sensor-check-for-fluid.2667/#post-32025 , we may already know the internal structure of this sensor.
