Wheel speed sensor issue?

I had the traction and ABS lights on, code c1206 for rear left. These sensors come as a cap that goes on the bearing, common problem, some people say water gets in and damages the sensor or the bearing. Bought a cap sensor from amazon. Before I changed it the code would not delete, and lights would not go off, so it was shorted, I am sure. Replaced it without removing the bearing, which was pain, son twisted the inner bearing metal ring on the inside, bent it back with a screwdriver, not sure if it affects anything. Put it back and lights went off, but I was still not getting any speed using the scanner, still reads zero. Is it possible these aftermarket ones are no good? Even if I bent the ring, am I not supposed to Get a speed reading at some point? I ordered a new whole hub assembly with the sensor. Using a probe, I was getting a ground from one pin, I tested the other wheel, and it was the same, one ground and one just reads.2 without indicating what it is, I guess it needed a signal while it was moving, but don't know how to do that. Same readings from the other wheel.
