My 99 Grand Prix GTP 138k ABS and Trac Control lights both came on at same time. Idk why, does anybody have a clue or guess as to what I could do to fix this?

And bad wheel speed sensor will make it throw a light for those at the same time. Also check ABS harness for cracks or breaks in wires or a bad connection
