I am guessing that is either a bad connection or the sensor is failing? I have read that a good sensor reads about 1.8kOhm.

I don’t know if you can point me towards a guide for stripping the sensor out?

The ABS light didn’t stay on this morning.

Thanks

Hope it is a wiring issue as the speed sensor itself is imbedded in the hub bearing and requires replacing that bearing. Along with a resistance spec, the sensor in question should generate an AC millivolt signal when the wheel is spun.
