To put it simply, modern vehicles have many interconnected systems. Traction control relies on your wheel speed sensors to function properly (as well as the ABS itself to brake individual wheels.) The traction control light is to indicate that the system is now disabled due to the ABS fault. The CEL is on because multiple vehicle systems are now disabled, and the CEL is the overall light that illuminates when something is wrong.
Replacing the ABS sensor should resolve the issue. You shouldn't need to do anything other than drive the car for a bit after replacing it. Worst case, you might need to clear the codes (if you don't have a scan tool, just disconnect the battery for a minute.)
