Are these chips enough to ruin this reluctor ring

If you look closely, you will notice that two of the teeth on this reluctor wheel are chipped. I get no reading from this wheel. I have swapped the wheel speed sensors and the problem remains on this wheel. I have tested the wire for continuity from the sensor all the way to the ABS module-all good.

this is a 2003 XKR 4.2 Supercharged.

This problem appeared when I changed the front strut top mounts. The problem, at this point, must be with this ring or the ABS module, and I can’t see how changing out the strut mount could have damaged the module.

Connect your ohm meter to the sensor and rotate the wheel. you should see a change in resistance for each notch.

I’ve heard that I can try voltage from the sensor while turning the wheel,

…but it is only supposed to put out .5 to 1 volt. My multimeter doesn’t read AC voltage that low.

What should the readings be when testing ohms?

I don't know the ohm reading but it should fluctuate back and forth, as in, on off on off on off. Maybe someone knows the values??? Hope it helps
