When cold (50-80 degrees) the ohms should be 10,800-17,900. When hot (180-200 degrees) the ohms should be 1,170-820. It's in a difficult spot, so it's easier to test if you take it out and use cold water and a heat gun to vary the temperature.

just to verify. there is that kind of jump in the resistance? 10k down to 1k? i know exactly where the sensor in question is so i will test it tommorow morning.
