you've copied the weblink for the thumbnail it seems, rather than the full image. Yes, they are pants lol.

Although yes also the trace looks very erratic too. But a better image would help.

That scope is just noise, the ECU isn't receiving anything useful.

90% of the time it's wiring, but could also be duff sensor.

not really, no.

Although if it's a hall sensor and you pass a ferrous metal object over it, it should switch between 0 and 5v, or something close to that.
