Dead Speedometer, Just Replaced VSS...Nothing Car has 77k miles on it, always been pretty reliable until yesterday on the way back home from after taking the GMAT, my speedometer decides to suddenly stop working along with the odometer. After doing a crapload of reading and researching last night, I narrowed it down to either the VSS or the wiring harness for it. Hoping it would just be the sensor, I installed a brand new VSS today (T56 btw) to no avail, so now I'm left to think it's the wiring, which I have NO IDEA how to route it from the PCM to the VSS if I had to rewire it, and I know the voltage has to be checked somehow at the wires but from what I understand they only give a reading if the wheels are moving... how am I supposed to lay under the car while moving the wheels at the same time? Thoughts and advice?

Do you still have the factory stereo? If so, does the automatic volume work? Turn the outer **** behind the volume **** all the way clockwise then check if the radio volume goes up at higher speeds. If it does then the problem is with your gauge cluster rather than the PCM or VSS. The radio uses the same VSS signal as the cluster.
