After having my 96 Cobra dyno tuned, my speedometer slowly started going out, and now completely doesn't work (which also took out the odometer). I don't 'think' the tuner killed it, because it lasted half the day once I left there, but I guess it could be an option.
I have replaced the vehicle speed sensor (VSS) and also the toothed gear that goes onto the sensor (last one was chewed up) - no fix.
So I went to O'Reillys and looked in one of their books/manuals they have for troubleshooting and found a few places to start. But this is where it gets confusing: It says to disconnect the harness to the VSS and with the ignition key ON, the reference wire should have 5 volts available. Then a different section right after that says to check for battery voltage.....which is it?!? Either way, I'm getting like 10.7V.
I'm not the best at troubleshooting cars, so could use some assistance here. Any help is appreciated!! It's getting old having to use an app on my phone for my speed lol
