Yes they are a passive device consisting of a coil of very fine wire, so there is potential for wire breakage.
Have you measured the resistance of a failed sensor? It would be interesting to take a failed one apart.
Yes, I have measures resistance which, generally, but not always confirms failed sensor so I only change that one. Doesn't always work though. Sometimes I have had to replace a sensor which appears good to clear the fault.
Tomcat59alan Reluctir rings checked, all teeth there and clean, but that wouldn't explain why new sensors work.... for a while

Datatek. I have a box full of "failed" sensors so I can certainly have a look inside a few. Any tips on dismantling?

My car currently has a broken reluctor ring. It has cracked, making one of the gaps slightly bigger than the others.
This caused the dash lights to come on with my old sensor but not my new sensor
