The ABS sensor on my pickup is borked, need ideas / help / a bigger hammer

[nermal]

Been chasing this for a while, 2016 Ram. The truck is showing error code C0037, which means that the signal for the driver's side rear ABS sensor is borked. This is a bit of a known issue for these, as the wire that goes to the sensor rubs against the frame and wears thru after a few years, eventually breaking the wire and causing the sensor to not read. It starts as an intermittent issue before the wire rubs through completely.

I found this out after replacing the sensor twice, and then after doing a scan and still seeing zero signal, replaced the entire wire. There was also a buncha crap stuck to the sensor every time I pulled it out to check it, so I blasted the bloody hell outta the tone ring with brake cleaner to try to clear it off in case that was causing something.

It's now reading, but sporadic. Below is what it's showing. The top is the "bad" sensor, the bottom is the good one on the passenger side. Any ideas what could be causing this? Could this be more dirt on the tone ring, a loose wire still, or a bad sensor, or something else? Looking for ideas on what to do to try to get this fixed. Any help greatly appreciated!

@nermal brake cleaner is pretty aggressive I’d be cautious spraying plastic electronics. I would try electrical contact cleaner.
Does the ring look in good shape? My old Malibu had rust flacking off parts of the ring tripping the sensor error

I suggest taking it to an auto recycler, having the vehicle crushed, get money for it as scrap metal and use that toward a new/newer vehicle.

Then take that new or newer vehicle to a high end car painting place and have it painted Savage Saphire Stratto Blue from House of Kolor:

@nermal Hmm, when comparing the troughs when you slow down it almost makes it seem like it's on the reluctor side. So either a contaminated or cracked ring or some excessive air gap. One would think that if it was wiring related that you wouldn't have that massive dive every time you had a reduction in wheel speed. It would be more random and would not correlate with the other sensor.

Common things I've seen are corrosion or worn hub/bearing debris causing intermittent signal via blocking or wearing a tooth/teeth. Also a cracked ring can cause a long gap and a funky signal.
