Vehicle Speed sensor
Anyone familiar with the VSS. My truck just threw a check engine code P0500 which is a VSS malfunction. At first I thought the tranny had gone, the overdrive button was flashing and it was holding the revs way longer before shifting and then when it did shift it was a real jerk. Then when I did a bit of research I found eveything was pointing to this VSS. The article I was reading said symptoms include irratic shifting, speedometer and oddometer stop working too. All this was what I was getting., Anyway, I am hoping this is not a big job. Where abouts is the VSS in my vehicle and is it a big deal to change?
Thanks, Shane

Its should be easy to change. On my truck it is located on top of the rear end. It also runs the rear abs. When you go to get one you will probably be better off asking for the abs sensor, otherwise the parts store will probably try to sell you the VSS for an older truck.

The VSS sensor is on the end of the speedomoter cable where it plugs into the trans. If you will crawl under the truck and look up at the tail shaft of your tranny @ aproxamitaly the 11 o-clock position (on the tailshaft) you should see the main body of the spedo cable along with a two wire plug on top of that cable body. where the two wirs plug in that is the VSS.

it should be on the rear-differential-believe they started in 90-is your speedometer still working??-if it's affecting the trans may be the speedometer-no allowing the vss signal to go to the ecm-had this problem twice on E250-

Yes, its a auto tranny and the speedometer is not working also. Thanks everyone for great info. I am still a little confused. I am not very mechanically minded although I am getting better. What does all this mean, am I looking at a big expensive job?

The sensor is on the rear end is held in by one bolt and has a two-wire plug on it.
The VSS/ABS sensor is located top center of the big round thing in the center.
All of that said it could be other things beside the VSS/ABS sensor.
Could be the sensor, tone ring, plug, wiring or the PSOM or fuses to the PSOM.
The wiring runs from the sensor to the PSOM and is "T"ed off (spliced) to the ABS Module.
If it is the tone ring you may have other rear end problems also.
If you take it to Ford it could be about $500.00 give or take a hundred.
