Temperature Sensor Not Working, Fiat, Alfa, Lancia
Sometimes the External Temperature sensor can fail for various reasons, causing inconvenience.
Today we will explain what happens when an External Temperature sensor on your car fails and why it is Important to Replace It. We will provide advice on how to correctly resolve the situation.
The External Temperature Sensor, as simple as it may seem, is a fundamental component that directly interacts with the engine control unit. When it fails, in addition to no longer correctly displaying the detected temperature on the screen, in most cases the car's air conditioning system locks up, causing significant discomfort, especially in the hottest or coldest seasons.
Furthermore, sudden warnings of ice on the road or vice versa might appear on the display.
In electric cars, however, in the absence of temperature data or with incorrect external temperature data, the battery will no longer be able to recharge, making it impossible to move the vehicle.
External temperature sensors, to be certified by car manufacturers, undergo rigorous and lengthy tests in climatic chambers, reaching extreme temperatures over +50 to below -50 degrees Celsius. These sensors are made with specific resins to ensure the complete impermeability of internal components. Tests are carried out with humidity values exceeding 100% and in the presence of salt spray, with tolerances to a tenth of a degree.
It is therefore clear the importance of replacing a faulty External Temperature sensor with an ORIGINAL component to ensure Comfort and Safety.
In Stellantis and PSA group vehicles, the External Temperature sensor is located in the side mirror, while in Ford, Kia, and Toyota vehicles it is located in the grille in front of the radiator.
