speed sensor on a 2000 f350
my cruise stopped working, then I started getting these faint beeps from under the dash, and then the speedo started jumping all over the place, and then the OD "off" light on the shifter started blinking......and then....everything went back to normal.
A few people suggested speed sensor, but it looks like there are more than one? (not sure I just checked rock auto breifly but they looked different).
How do I know which one to replace? Even better, since there are no check engine lights can it be scanned to determine if that is truely the problem?
