Why does the temperature gauge not display the water temperature?

[StLeilani]

Here are the reasons why the temperature gauge does not display the water temperature: 1. The power line of the temperature gauge is broken. 2. The heating coil of the temperature gauge is burned out. 3. The heating coil of the temperature gauge sensor is burned out or the contact is poor. 4. The wiring of the temperature gauge sensor is poor or broken. Here are the solutions: 1. Check the temperature gauge. 2. Check the wiring, and see if the plug has poor contact or if the plug is not properly connected. 3. Check the temperature sensor. Check if the water temperature is damaged and if its plug has poor contact or is not properly connected, then open the radiator cap to see if the water in the radiator is not hot. If the water temperature is low, consider whether the radiator is malfunctioning. If the water temperature is normal, consider whether the sensor is malfunctioning.
