Well I think that I found the sensor. It is in the head on the front
left (drivers) side of the engine. The only weird thing is that the
book shows a single wire going from the temp guage to the sensor which
is then screwed into (grounded) to the engine. My car has two green
wires going to the sensor. A number of mechanics have looked at this
sensor and have said that this has to be the temperature sensor but no
one knows why the two wires? The sensor is just a temperature sensitive
resistor that is in series with the guage which has 12V going to the
other side of it. According to the Alldata diagram we pulled the guage
is mearly a voltmeter really. So there should only be one wire going to
it. Thanks, Lenny
