I have a 97 Grand Prix GT and the ABS, Traction Control and Check Tire Pressure lights remain on when driving. I figure that I have a bad wheel speed sensor, but I don't know which one. Since the traction control light is on, I am assuming that it is probably one of the front ones, right? I tried to check it with a code checker, but it didn't register any codes.

Anybody have any ideas on how I can figure out which speed sensor is bad?

First thing i would do is a visual inspection of all the sensors and tone rings (on the axle shafts or brake rotors).If you dont find a missing tooth or broken wire then a good scan tool that has data stream capabilities should let view the output voltage of each sensor while your driving.
