There is no sensor.

The oxs light comes on after a certain number of revolutions of the
speedometer/odometer cable. It indicates when you have traveled 30k
miles, and a reminder that you O2 sensor typically craps out at 30,001
miles, or thereabouts, leading to crappy performance, gruesome mileage,
and general mayhem. Subsequently, you come to the Vanagon list and cite
a bunch of symptoms you are seeing on your van, only to be rebuked when
folks find out you ignored your OXS lite. Yours may be loose, and thus
the flicker/intermittency.

After replacing the $30 O2 sensor, follow the speedo cable from the left
front wheel upwards toward the deck plate under your left foot(while
driving). Find the little black box that the cable runs through. On that
box, find the white button, and push it in deeply (2cm) until you hear a
CLICK!

You're set for another 30k.

Subject: 85 water-cooled Vanagon and OXS

Hello all, I am sure that this has been covered, but...

The oxygen sensor light in the dash of my 85 water-cooled Vanagon keeps
coming on for a while, then going off.  Any common causes?  Should I
simply replace the sensor?

Thanks for any input, it is greatly appreciated.
