I want to make sure that my temp gauge is functioning correctly and I was going to make sure that the sensor is doing its thing first.
I am amazed at those tolerances though.....they are huge!!
Looks like I will have to pull the sensor out and bung it in the kettle......dang.

The large tolerance is at the lower temperature end which is prety much irrelevant.
All this means is that to check if your sender is operating properly, next time you have your car up to normal running temperature with the radiator cap on, remove the wire from the temperature sender and measure the resistance between the sender terminal and earth. It should be between 24 and 27 ohms.
If your resistance measurement is less than 24 ohms you "might" have a problem.

Sorry mate. Just reread your original post, those tolerances are much nicer......Thanks for the help.
Any idea what the sensor itself is made from?? I dont know of anything apart from carbon that has a negative temperature coeffecient. Just curious .
