Newbie here... Searched for posts but couldn't find one that matches my symptoms and was hoping someone could help.
2003 F-250, 6.0L Diesel, 4x4, 6 speed manual.
Speedo works normally until 59 MPH and then stays there no matter how much faster is attempted. When slowed back to below 59 MPH speedo works normally again. All other gauges seem to work normally the entire time. Obviously no OD light since I have a manual, no ABS light either. Odo seems to work, even when speedometer is stuck at 59, but hard to tell if it's working at the correct rate.
Based on the posts I found, Seems like the VSS would be the place to start, then the ABS sensor, then the cluster itself. Am I on the right track? Any other suggestions?:ford:
