My odometer stopped working, my speedometer does not work at all unless I am going over 70 mph and it will swing up and down and then when I get back under 70 mph it turns back off. My check engine light is also on and the shop cannot figure out what is wrong. It used to just turn itself off when I was driving but it stopped a month ago and has not done it again yet. My friend's boyfriend replaced the speed sensor that is on the rear axle but it did not help. Please help.
