[s-cars] engine speed sensor fault code (G28)

[Theodore Chen]

i ran the VAG-COM diagnostics on my '92 S4.  the only
code that came up was engine speed sensor (G28).
however, the engine was not running at the time i checked
codes.  the check engine light never went on.

sounds like i don't have a problem there.  but why don't
i get a code for the reference sensor, if it's the same
kind of sensor?
