As said, usually once over (IIRC) 10mph they should reset. It also begs the question of what hubs you fitted. Did they come with the sensors, are the sensors Wabco, do the hubs have the correct number of teeth on the reluctor ring, (60), the cheap ones often do not? Even though the hubs are new, is there any play in them, the cheaper hubs even when torqued up properly often still have play in them, which will upset the sensors? You need to establish what or which hubs are causing the issue, ideally using a diagnostic. You can also check the resistance on a sensor by disconnecting it at the plug end and reading across the pins. They should read between 950-1100 ohms, and should be all very close to each other.
