Re: 94 speedometer inop
Got some ideas, but w/o a DTC nothing makes sense. If VSS to PCM circuit was open you would get a DTC, if PCM to speedometer was open circuit then you would get a different DTC. Circuit is an analog sine wave from the VSS to PCM then the PCM puts out a digital signal to the speedometer and cruise control. Any open or short will cause a DTC. Voltage and grounds to dash and cruise are different sources. If you had a scanner with speed info you could verify VSS to PC is OK or not that would isolate the problem a little. If it worked before the accident and does not work now take it back, insurance should cover total repairs, or the shop, if it left some connection incorrect.
