Do you see a fault in the reading of temperature? In that case, it can be due to a broken coolant temperature sensor. If the issue is clear, you can find a solution so that all the parts of a car work properly. You can even take the help of professionals who will give you details on how to recover.
If you are facing a problem with the temperature gauge, it becomes easy to find reasons. Once you are clear with the cause of such an issue, you can find an option to fix the problem.
There are various things that you can opt for:
- Correctly, a car indicates a specific code of the concerned issue; you can read all the code to understand how to come out of a problem clearly.
- You can diagnose the coolant temperature sensor thoroughly, find the solutions, and get it working correctly and efficiently.
- Now it’s time to test the thermostat if it does not seem a good option.

What Would Cause My Temperature Gauge Not to Work?
The broken coolant temperature sensor is one of the main reasons for the fault in the temperature reading. It is the crucial part of a car located near a vehicle’s thermostat near the radiator’s base. Such an issue might turn devastating; consulting professionals at the right time will be best.
Are you facing an issue with the reading of the temperature gauge? The situation can be too low, high, or with fluctuations. Here is a matter of concern for you will regard the reason for such an issue. The problem can be the engine, gauge, or other car parts.
In most cases, the gauge’s temperature remains accurate, but sometimes there is a fluctuation. In that case, you can do proper research and reach goals that will affect their work.
Initially, you can inspect by having either working period of about 20 minutes. You can pop the hood and check some of the essentials.
- Initially, notice the coolant level; it should be at the full hot mark on the coolant reservoir tank. If there is a low level, then it could lead to overheating.
- The color of the coolant should be either green or orange. If the color is rusty, it indicates a contamination situation that might lead to overheating.
- Running of the coolant fan starts at 230 degrees Fahrenheit, which usually occurs after 20 minutes of engine operation.
- Make a comparison of the temperature that is of the engine head, and bear the thermostat and upper radiator hose.
Will the Radiator Fan Work if Temperature Sensor is Not Working?
In modern cars, control of the cooling fan is in the hand of an Engine control unit; it will get the timing signals from the coolant temperature sensor. If the sensor has a problem, the fan won’t work when needed, creating overheating in the engine.
Generally, a car cooler fan plays a crucial role in cooling the engine. If the fan does not work, it causes a good amount of heat in the engine; in the future, the damage can be in different parts of a car.
It is a severe problem concerned with a vehicle, so their recovery should be on time and with good results. If you notice a yellow or red light at any time, you add some basic activities to daily life.
- Pull over on time when you think the situation is not the same
- Turn off the engine light
- Get proper checking car in the garage
- You can contact professional for help
Some common reasons lead to a problem with the cooling fan. Once the reason for the fan’s improper working is clear, you can reach desired goals on time.
- Blown A Fuse: Radiator fans are known to be electrical, so there might be a problem with the fan’s working. In the manual, you will get details on how the cooling system will work; if required, you can replace it.
- Fault in Temperature Sensor: The cooling fan is mainly done by the Engine Control Unit that gets signals from the coolant temperature sensor.
- Defective Fan Relay: The fan relay will have control over the power of the cooling fan; if the relay has a problem, the situation might be affected.
- Wiring Issue: Faulty wiring could be the main reason for the issue in the car. Ensure that you check the wires properly and connect them in the proper order.
What Does It Mean When the Temperature Gauge Doesn’t Move?
Coolant temperature is the main reason that leads to a situation in which temperature doesn’t move. The main reason for a case can be bad wiring or an issue with the sensor. Some problems can also lead to a stuck thermostat, causing a lack of heating in the engine.
There is not a single reason that will stop working of gauge. If you have a complete idea of the reason for the situation, then only finding the desired solution is possible. Things will become simple if you have an entire idea of the detail in advance.

- Broken Wiring
- Faulty Gauge
- Corrosion in Plug Connectors
- Bad Thermostat
- Air in Cooling System
- Broken Engine Control Unit
Can the Thermostat Cause Fan Stay on?
Yes, the thermostat causes the fan to stay on for an extended period. If the working of the thermostat is not proper, then it will lead to a situation that might lead to improper working of the car.
Mainly the fans in a car will last for about an entire time. If you are facing an issue with working if a fan is in a vehicle, consulting a professional at the right time is advisable to act. If you keep on driving a car with a bad working fan, then it might create a situation of overheating in the car.
Are you planning to check the relay of the radiator fan? If yes, the first thing you need to do is locate the relay available on the radiator.
Now it’s time to check the continuity in terminals with the help of a voltmeter. If you notice no continuity, the chance of the bad relay is higher and requires a replacement.
