Is 4.3 V enough to power abs sensors?

Not that familar with the hall effect though i did do a quick search on it. It read 1243 ohms resistance which wabco says is in spec? some of the voltage coming out is around 10 then on others its 4.3 (ecu out that is) ... been at this for two days, wires look pretty good. Bad ecu maybe?
