Vehicle Speed Sensor

[denislmorin]

I have a 1994 E-350 Econoline Motorhome. When I drive on the Highway the speedometer goes haywire, my ABS light is always on and sometimes my cruise gets disengaged. After reading up on the problem the likely culprit is the Vehicle Speed Sensor. Any idea where this is situated and whether it can be changed by myself? Thanks

Just want to say thank you very much j-d, if you're still out there.  I have a 1993 E350 Damon Escaper with the auto trans and 460 ci engine. I had numerous symptoms, bouncing speedo, irregular shifting, Rear ABS light on, even popping into neutral sometimes. Pulled and replaced the speed sensor on the transaxle per your excellent instructions, and all is well.  Thanks again. Bob

I would be very concerned that your brakes may not work right in a hard stop.

The brakes will work just fine, just no anti-lock capability.

Mine has 3; one on each front wheel and one on back axle.

I just got it safetied and I was told by the mechanic not to worry about the ABS light being on. I found where the VSS is located. It is on top of the rear differential. Now to see about ordering the part.

On my 99 F250 it was on the rear axle. Don't know if you could change it.
