93 rear speed sensor help
Did I do this right ,removed the ear speed sensors cleaned ( were dirty ) sprayed brake cleaner in the hole cleaned the wheel that the speed senor feeds off of is clean looks good . Volt mender set on volts probe on one side and one on the other nothing switched the leads still nothing ,had to turn the hub by hand but was fast enough to make Volts . I did the fronts the same got 3-4 volts .. I seen on you/tube the guy has the motor running ,not happening on this one waiting on new OPTI spark .. Both bad ??? Any surjections .. Thanks ..

You may not be able to spin rear tires to get a reading. Sensor needs to be seated in knuckle, sensor won't pickup if there too much air gap. I would recheck it when engine starts.

You can ohm test the sensor at the connector, while it is out of the car.
