The traction control and several other systems in the car use the inputs from the speed sensor to function. When the speed sensor malfunctions it can effect the traction control, and show you the slip indicator light and a check engine warning light. You should start by replacing the speed sensor, or inspecting it to see if it is damaged or dirty. Good luck!
