If the temperature gauge needle doesn't go back to zero when the car is shut off, it is possible that the needle is sticking. A little WD-40 or electronic spray on the gauge might fix the problem. There could also be a problem with the MAP Sensor or a Radiator Pressure sensor in the engine.

Why doesn't the temperature gauge needle go back to zero when the key is turned off?
That is the way it is designed. When the key is turned on then it reads correctly.

Repairing an inoperative gas guage on a 1997 Buick Park Avenue. Needle stuck behind stopper pin?
Have fixed this issue many times... you need a STRONG magnet. Turn the ignition off, place the magnet over the gauge (on the clear plastic cover over the gauge cluster) on the end of the needle... it will react to the magnet and move when you move the magnet. Simply rotate the needle back into its proper position. Raise the magnet up... if it stays in the position, turn the ignition on... if your gauge is not broken, the needle should be reset and function properly.

Can a temperature sensor make gauge go back and forth?
Yes, a temperature sensor can cause a gauge to fluctuate back and forth if the sensor is experiencing rapid changes in temperature readings due to environmental factors or sensor malfunction. For instance, if the sensor is near a heat source or is affected by drafts, it might send inconsistent signals to the gauge. Additionally, if the sensor's signal processing is faulty or there is electrical interference, it can result in erratic gauge behavior. Proper calibration and placement of the sensor are essential to ensure stable readings.

How do you check the temperature of a swimming pool?
The gauge on the pool filtration equipment is there to indicate back pressure in front of the pump. Most of them have a section that is done in red, when the needle reaches the red it indicates that the filter needs cleaning. Otherwise when the gauge gets about two thirds up you should clean the filter. Your judgment with this will improve with time and experience.
