Yes, ie yes could be, not yes is.

It's quite possible that the antiseize poisoned your sensor and ruined
it.  I did it to one of Jon Casey's a month ago by being thoughtless -- the
sensors come with a dab of "safe" antiseize already applied to the
threads.  This was a reinstall and I don't know what/where to get stuff
that's safe -- it may even be that they simply are very careful where it's
applied, though I doubt it.  Anyway, Jon's lasted about five or maybe ten
minutes before it was toast.

I doubt that it would interfere with the connection though, if the sensor
were tightened reasonably.
