    Gentlemen, after a long online research and calling experts, I found a very interesting website with a few articles about this thread that I started, I hope it helps many of us. The sensor does not last forever. Here are two samples:

    http://www.underhoodservice.com/diag...ature-sensors/

    http://www.underhoodservice.com/satu...rature-sensor/

    Thanks to everyone who read and/or replied here.

    It looks like I will have to ignore the warning that I received here about changing or messing with the sensor, since I already bought a new AC Delco (made in Israel) one.

    And, BTW, I mentioned something wrong above, when I said that the voltage coming to the sensor was 1.2V. I measured the voltage between the two wires coming to the sensor when it was unplugged and that was wrong. I just measured each of the wires with respect to battery ground and they were 0 and 5 volts.
