94 grand am speed/tach

help, my 94 grand am just lit the abs light, and the speedometer now acts like a tach, i.e. reads rpms not mph. any suggestions?

Sounds like your VSS sensor to me, Especially since your ABS system uses your VSS as a reference to know when your skidding. I say get it scanned or just replace the sensor.
