ABS light on
2000 F350 PSD - ABS light came on yesterday - anyone have any advice for troubleshooting or what part(s) might be bad? Is this a common failure - 112k mi on it.
Sounds expensive :-(
thanks,
mike

Doesn't that sensor also cause the OverDrive light to flash? My OD light is not flashing.

Doesn't necessarily flash the OD light, but it may make the cruise control shut off and the speedo may dance.
If it is the speed sensor it is extremely easy to replace. However, with your miles, it may be worthwhile to change the diff fluid too. Sometimes the speed sensors chews up the part inside the diff that makes it work and leaves junk in the fluid. With 112K miles it is probably time anyway.
Good Luck,

For the record, from what I've read the last few years about this subject:
The VSS may light the ABS light, flash the O/D light, and/or make the speedo jumpy.
That's right, one, two or all three symptoms may show up, or not.
My theory on it goes like this:
The ABS will detect even one "tooth" missing (or a better way to explain, one "pulse") from the VSS
The tranny will deal with it fine until the speedo starts to jump (which might not even be detectable to the human eye) and then the O/D light MIGHT come on.
The speedo won't jump until there is a drastic loss of pulses from the VSS.
