02 Monte Calro SS - Traction Control/ABS Issue

[Holly_123]

On my 02 Monte Carlo SS, the traction control light, ABS light and service traction system light are all coming on together now as of this morning. My low tire pressure light has been on for a couple months now and when I would add air, the light would stay on, (tires are practically new). I'm thinking it could be a bad wheel speed sensor but not sure. If it is a bad wheel speed sensor, is there any way to tell which hub assembly it's in without having to take it to the dealer? Any advice would be greatly appreciated.

Must be scanned on an abs function scanner to pick out the suspect component.

Although I had hoped otherwise, I figured I'd have to take it in for this one. Thank you for your reply.
