OK, thanks.

I'll take off the sensors and measure again.... if open I'll replace. Strange that both read almost the same..... left is 0.9 ohms, right is 1.0 ohms. The upper limit of spec is ~1k ohms and the lower limit is 0.85 ohms - so both are near the lower limit as measured before removal. It sounds like they start life with a higher resistance value when new but degrade toward open with age and/or use.

Should I also take off the rotor and clean the hub ring that the sensor reads?
