My out-of-warrenty 2002 XG350's speedometer quit working on the way home
from work the other day. All of a sudden it was reading 0 mph. The tach
was still working, and the car seemed to be running fine. After noticing
this, I was just about to engage the cruise control to see if that was
working or not, when the speedometer jumped back to life and has been
working ever since. Anyone seen this behavior before, or know what to do
about it?

Thanks

Usually, the problem is with the vehicle speed sensor or the gear attached
to it. It's nearly impossible to tell which is faulty without trial and
error, so I usually just replace both at the same time-- they're part of
the same assembly.
