Hey guys. Speedometer quit working, check engine light came on. Got a cheapo OBDII scanner and got to use it for the first time. Instead of a code though, it just told me the problem. "Vehicle Speed Sensor A Circuit."
A quick googling told me there are two sensors, one on the transmission and the other...elsewhere. I figured screw it, I'll just ask the experts. Which one is the "A" one?

 

If it's the truck in your sig, then its the one on the rear diff.

 

Thanks Hey You. Yet another of my dumb questions answered. As always, i appreciate it.
