What causes a temperature gauge to stop working?
However, there are other reasons, for example: A bad temperature sending unit (the second most common reason) A problem in the temperature gauge’s electrical circuit A fault in the control circuit from the car’s computer (depending on vehicle model) A bad temperature gauge
Why does temperature gauge not working?
There are many reasons your car’s heater isn’t working. Maybe the fan is malfunctioning. Perhaps your temperature gauge is running below normal. There could even be a puddle of liquid under the front of the vehicle. A lack of heat can be a symptom of a much larger problem.
Why is my temperature gauge in my car not moving?
Reasons Why Your Engine Temperature Gauge Stays on Cold Faulty Engine Coolant Temperature Sensor. The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself which is sending the information Faulty Gauge/Cluster. The next most common problem is a faulty temperature gauge. Broken Wires to the Sensor Or to the Gauge. Bad Thermostat.
Why is the engine coolant temperature gauge not working?
Another common reason for a faulty temperature gauge is air making its way into the radiator hoses. Air can pool near the temperature sensor or the thermostat and cause faulty readings (or no readings at all). It can also affect the car’s overall cooling efficiency.

Why is my car temp gauge not working?
One common cause of a temperature gauge that malfunctions is the thermostat. Sometimes the thermostat gets stuck open, which can cause the temperature gauge to “warm up” slowly, never move back down to operating temperature range, or fluctuate randomly. If the thermostat is not stuck open, it may simply need to be replaced.
Why is the coolant temp gauge not working?
If the coolant temperature gauge is constantly fluctuating then the most common cause of this is a bad thermostat. If the thermostat is sticking or not opening and closing right then this will occur. It can also be a clog in the radiator or a water pump problem. If the engine has never gotten too hot then the thermostat should be replaced first.
What would cause coolant temperature gauge to stop working?
The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle’s thermostat near the base of the radiator (consult your owner’s manual or repair guide) can get gunked up and fail.

Disconnect the temperature sensor’s wiring connector.
What does it mean when your temperature gauge is too low?
Unfortunately, when the temperature gauge reads too low, too high or fluctuates, you don’t know whether something is wrong with the engine, the gauge, or something else. Unless the gauge is in the red zone and you see steam coming out from under the hood, of course.
What does it mean when gauges in your car stop working?
But when the gauges in your car stop working, it’s not a situation you can safely ignore. When one gauge stops working, the problem may be in the gauge itself or a bad sensor, while all the gauges cutting out at the same time often indicates a blown fuse or a defective instrument cluster.
Why is the temperature gauge on the dashboard not working?
Thus, the temperature gauge on your dashboard is your window into the coolant temperature as seen by the temperature sending unit. It lets you know when the engine is cool, at operating temperature, overheating, or fluctuating. The sending unit is a thermistor. It is exposed on one side to engine coolant.
What to do if your coolant gauge is not working?
Using your coolant temperature gauge as an example, the diagnostic procedure involves locating and disconnecting the sending unit. With the ignition on, the gauge should register cold. If you connect the sending unit wire to ground, the gauge should switch to read hot.
