Yeah it will be a problem with your rings not the sensors. First just check you have the toothed ring on the cv joint, as non abs cv joints dont have the ABS ring. If this is the case you either need to get new cv joints, send the old ones back or swap the old Toyota ones to the new hub.
If you do have the rings on, you can swap over the old Toyota rings. They take a fair bit of beating to come off, be careful as the metal teeth can be damaged easily. Once on just clear the codes using the pump pedel reset sequence, then drive for a bit, try it a couple of times if it does not reset at first.
Also just compare the old Toyota rings with the new ones fitted, if they are not identical then you may have the wrong rings on. I had a problem where the supplier had issued some CV joints with wrong size of cv joint rings.
Where did you buy the new CV joints from? Did you specify ABS CV joints?
