there should be a warm-up time from the first start.. It should take a few minutes to get from cold to normal operating temp on the gauge. With my car (same year & model) a 2 hour sit wont make the gauge go down that much..And the normal reading should be a "tick" past half way.. You can always perform the gauge test but i dont think it would do any good if it were the sensor..
