Still working on my dead speedometer/no odometer increment problem.
This morning I disconnected the negative battery terminal and unbolted, sanded clean & shiny, and rebolted up all the ground wires I could find in the engine compartment. No change.
Took the cluster out and checked to ensure all connectors are in tightly. Reseated every connector under the dash I could get to. No change.
My buddy and I plugged in a live-data scanner and went on a drive. TPS works fine. Vehicle speed stayed at zero the entire drive.
So... my question: does the signal going from the VSS to the OBD-II port run through the cluster first or directly to it? I'm trying to figure out if (with the diagnostic showing zero mph) that means that the VSS and/or wiring to the OBD-II port are bad, or if the speed signal to the OBD-II port is fed from the cluster (perhaps further implicating the cluster as the bad culprit).
