I have a 96 Contour and both my ABS and T/C light come on after a certain speed. I read in my manual that the ABS sensors output an AC voltage signal. I got out the multimeter and read both rear sensors and found one to be higher than the other. I then pigtailed one sensor so that it was sending the signal for both back tires and the light didn't come on. I then switched the sensor sending the signal and the light came on. I now know that which side I am having the trouble on, but is it the toe ring that is bad or the sensor itself? Also has anyone removed the sensor? I took out the one bolt I could see but it still didn't want to come out. Any help would be appreciated.
