Try replacing the little voltage regulator under
the dash cover.  If not that then I suspect your
wiring.  I'd take a good look at the end that
plugs on to your sensor.  A recent poster just
talked about this and found bad corroded wiring.
And your van isn't a spring chicken anymore...

Good Luck,

Steven
