Is it normal for the outside temperature display to show over 50 degrees?

It might be due to a faulty outdoor temperature sensor, and it is recommended to have it checked by a professional technician. Here is some relevant information about temperature sensors: 1. Function: They utilize the principle that various physical properties of substances change with temperature to convert temperature into electrical signals. 2. Classification: Based on measurement methods, they can be divided into contact and non-contact types. According to the materials and electronic component characteristics, they are categorized into thermistors and thermocouples. Contact temperature sensors have their sensing parts in good contact with the object being measured, also known as thermometers. Thermometers achieve thermal equilibrium through conduction or convection, allowing the displayed value to directly represent the temperature of the object being measured.

The outside temperature display shows over 50 degrees Celsius. I've driven for many years and have indeed encountered this during road trips in hot desert areas—it's normal for the temperature to rise above 50 degrees due to strong ground heat radiation. However, if it frequently shows such high readings in ordinary cities or regions with distinct seasons, it's likely abnormal, possibly due to incorrect sensor placement—like direct sunlight exposure or proximity to the exhaust system heating it up. After parking, compare it with the real-time temperature on a weather app. If the difference exceeds 10 degrees, it's worth suspecting an issue. I've dealt with similar cases—sensor aging or dust buildup can cause inaccuracies, which can be fixed by cleaning or replacing the sensor. Inaccurate temperature readings affect AC efficiency, making hot days even more uncomfortable, so get it checked at a repair shop promptly. Driving safety comes first—don’t overlook such details. In short, judge accuracy based on the environment.

As a young driver who frequently hits the road, I'm quite sensitive to temperature displays. While showing over 50°C might be realistic during extreme heat, most cases are actually sensor malfunctions. These sensors installed near the front grille or wheels easily get heated by engine heat or direct sunlight. I've witnessed situations where the display spikes right after opening the car door, then drops after turning on the AC. Inaccurate readings cause the AC to adjust fan speed erratically, which is utterly annoying. Compare it with ambient temperature - like touching the car body when parked. If there's significant discrepancy, check if the sensor is blocked by dirt. Don't delay repairs, as driving in summer heat is unbearable. I once ignored this issue and ended up with increased fuel consumption. Addressing minor problems early saves both hassle and money. Paying attention to these signals during daily driving does no harm but only good.

I commute by car every day, and the temperature display showing over 50 degrees is quite abnormal, as the normal peak outdoor temperature in summer is around 40 degrees. If it consistently shows like this, it's likely that the sensor is faulty: either its placement is being interfered with by direct sunlight, or the wiring has aged and malfunctioned. Once, my display showed an abnormally high reading, but after stopping and restarting the car, it returned to normal. I recommend comparing the displayed value with the weather forecast. If the discrepancy exceeds 5 degrees, take it to a repair shop for inspection to avoid air conditioning failure affecting comfort. Repairing it doesn’t cost much but can improve driving experience and safety.
