Same old ABS, O/D flashing, speedo droped off
Not new to the forum (use it all the time for information), just new to posting.
The Vehicle is a 2001 F250, 7.3L 4X4 142,xxx miles. Exhibiting the standard Rear VSS problem. First visual inspection of the plug, wires, sensor all looked ok but I replaced the sensor anyway and none of the problems went away. Next, visually inspection of the tone ring through sensor hole by jacking up the rear diff and rotating the tires, it looks ok. Also, checked the ground by the drivers headlamp mentioned in a thread on here.
Let me back up, first the ABS light was just fading in and out randomly for almost a month and never left any codes behind, no other problems. Then the ABS light would stay on longer, and the speedo started bouncing. This lasted about a week. And this past weekend it gave all symptoms and has not gone away. During all of this I don’t know if the service engine light came on at all, as it has been on for a glowplug problem that I have not had time to fix yet for the duration of this failure.
I could not get any codes from the ABS System because my scanner could not communicate with it. But there were no additional powertrain codes.
I am at a loss as to where to look now, any help would be greatly appreciated.
Thanks in andvance for anything.
