I would disagree. Good for a couple of
years? They often go 15+ in our vanagons
before failure!
Again I've talked to the sources and
although the failure of a new sensor is
not impossible it is uncommon.
Low temps = high resistance. He most
likely has a ground, wire or gauge issue
before a bad new sensor.
We still need to know why is fan is not
running!
