1999 Anti-lock brake problem

I have a 1999 K1500 with about 100,00 miles on it. I have been having problems with the anti-lock brake system. The anti-lock will activate when trying to stop regardless if it is icy or not. I have checked the wheel sensors and they are not corroded. They also let current pass through with an ohmmeter. I have recently replaced the front pads, rotors, and calipers. I also bleed the system several times thinking there might be air in the lines. When I disconnect one of the wheel sensors the light comes on and the brakes work fine. What do I need to check next?

you will need a millivolt volt meter remove connector to sensor measure voltage out of the sensor with wheel spining by hand should read 500mv.....test other side should be the same if one side is less remove sensor and inspect for debris on head of sensor.. if sensor clean and not pushed out from rust sensor is bad but this is usually not the case......
