ABS and Brake light on; speedometer jumping
When driving at higher speeds the ABS and Brake lights will come on, sometimes making the dinging noise, and the speedometer will start jumping around erratically. Usually the speedometer will jump around within 10mph of where it should be, but sometimes it will peg out at 120 and stay there a minute before returning to normal speeds and jumping again. I'd read on a google search that it could be a brake sensor that the speedometer sensor routes through? Any help would be greatly appreciated.
