Temperature Fluctuation simply
A faulty temperature sensor, a wiring issue, or a blown fuse could cause a temperature gauge to stop working. It could also be due to a malfunction in the gauge itself.
A thermometer measures temperature, while a rain gauge measures the amount of precipitation (rain) that has fallen.
The outside temperature gauge reading "F" likely means that the sensor cannot detect the temperature. This could be due to a malfunction in the sensor or a problem with the wiring. You may need to have the sensor checked and possibly replaced by a mechanic.
Heat which causes a change in temperature of substance is called specific heat.
The pointer on a thermostat moves when the room temperature changes. This change in temperature causes the thermostat's sensor to detect the difference and adjust the pointer accordingly to indicate the new temperature reading.
probably fuel pump.

change in temperature causes change in pressure

The temperature sensor is probably bad

bad temp sender usually. Bad gauge rarely.
Low coolant due to a leak is a very likely cause.
Could be the coolant temperature sensor.
Urine is the same temperature as the body it leaves. If the person has a fever, the urine will be a higher temperature. This is why there is a temperature gauge on the outside of a sample bottle.
Bad Gauge---Electrical short---Bad fuse---Bad sending unit---loose or bad electrical connector to the gauge. Bad sensor. Had a faulty gauge on my 97 Ford Ranger. I changed the thermostat and the sending unit and the temperature sensor it started wotking beautifully.
change the temp switch first and if its the same as before then someone has taken the thermostat out which causes the engine to stay cool.
