O2 sensor damage?

[Gregory A. Parmer]

So the light may drop out and come back on?  I'll add any details
you can provide to the assembly guide. The more complete our
info the better.

FWIW--mine comes on bright, then dims a bit. The voltage across the
LED seems to oscillate (faster than a DVM can display). I'm measuring
at the tailpipe with the Dataq DI-194--neither of which may be considered
optimal. Readings imply correct function though.
