I don't know about stock. My sunpro sender reads about 1500 ohms cold and 135 ohms hot. Yours should be close. Seems like everyone has their own standard, so an aftermarket sensor likely won't work with a factory guage and visa versa.
The temperature coeficient is inverse - hotter makes lower resistance. Full scale readings is a sign of short circuit, a bad, or mismatched sensor.
