I have a 2005 Mazda 6. Car runs fine - but - on my dashboard, the Emergency Brake light, the ABS light, and the 2 traction control lights are on all the time. This disconnects the ABS capability. At first this happened only when the car was cold (and by cold I mean back in the winter). Now they are just on all the time. I understand that this may be due to a failed or dirty sensor. Apparently there is one for each wheel and one at the transmission (mine is a manual).

Anybody else have this problem? What did you do?
