Finished a cooling system overhaul and immediately after lost speedo,mpg, and odometer. My abs light is on but that has been on for a while. Did I forget to plug something in? My assumption is that my rear sensor is bad, maybe even just dirty. But I don't know which sensor is for the speedo, as some forums say left and others say right side. I know my car has 1 sensor on my U.S. driver side that goes from the junction box to the wheel. And two sensors from the junction box on the passenger side. Any help out there?
