Thread: ABS sensor replacement - Long Lead

I hadn't thought of it that way, but your right. And in hindsight, mine may have been this as well. But because I changed the sensor lead, as well as the sensor, fixed it (however temporarily), I just assumed the lead was the problem. No matter though, because after the reluctor ring got hold of the sensor, it was academic. It ripped the end out of the sensor, and then the pointy bits of metal protruding from the end of the sensor wore a definite groove in the teeth of the ring. At that point with another sensor in (temp fix just to fill the hole until I could get the new hub), the system would be ok for any where from 30 meters to 3km. Essentially it would take however long with the increased distance between sensor and ring, for the system to register enough low readings to trigger the fault.
These were Britpart sensors as it happens, and I'm not sure the extra length is either consistent or intended.

Bit slack on this, but I have finally taken photos of the buggered sensor.





As you can see, the reluctor ring has ripped the end out of the sensor, which in turn has worn away at the teeth on the ring.
