Why does the tire pressure monitoring show an abnormality?
4 Answers
Tire pressure monitoring showing an abnormality indicates that the air pressure in the four tires is not within the normal range. This is usually caused by slow leaks or punctures leading to insufficient tire pressure, or excessively high tire pressure, which triggers the tire pressure warning. More detailed information is as follows: 1. If the engine is the heart of a car, then tire pressure is its blood pressure. Tire pressure is crucial to the performance and power of the vehicle. When tire pressure is abnormal, the tire pressure monitoring system does not prevent the car from moving. Therefore, before each drive, the owner should statically check whether the tire pressure meets the specified value. If not, do not drive the vehicle, as it may damage the car or cause personal injury to yourself or others. 2. If abnormal tire pressure is detected while driving, check the tire pressure immediately. If the low-pressure warning light comes on, avoid sudden steering or emergency braking. While reducing speed, move the vehicle to the roadside and stop as soon as possible. Driving with low tire pressure may cause permanent damage to the tires and increase the likelihood of tire failure.
As a seasoned driver with over 30 years of experience, I've seen plenty of tire issues. When the tire pressure monitoring system shows an abnormality, there are usually just a few common causes: the tire might actually be leaking and the pressure is low, triggering an automatic warning; or the tire pressure might be too high, exceeding the range and causing an alarm; or the sensor's battery could be dead or damaged from impact, leading to errors. In winter, cold air causes the fastest pressure drops, so abnormal alerts are common. Quickly find a safe place to stop and use a portable pressure gauge to check the tire pressure. If it's normal, it might be a sensor malfunction, and you'll need to visit a repair shop for a replacement. Don't underestimate this—driving for long periods accelerates tire wear, increasing the risk of a blowout on the highway. During regular maintenance, have the mechanic check the system to ensure its sensitivity. Last year, I ignored this before a long trip and ended up stopping midway for repairs, which caused delays.
As an urban office worker who commutes by car daily, I find the tire pressure monitoring alarm quite annoying but impossible to ignore. The reason is simple: either the tire is underinflated or the sensor is broken and can't send signals. I connect my phone to the car's app to check the specific values—add air if it's low, release some if it's high. The sensor battery usually lasts five years, and when it's time, it stops working and needs replacement. Delaying action increases fuel consumption and damages the tires. In summer, heat expansion makes the pressure unstable and prone to errors, so it's best to pull over and check. Buying a new sensor online and having it installed by a professional is cost-effective—safety first, don't risk driving. The issue isn't as complicated as it seems; five minutes to adjust the pressure and everything's back to normal.
After having kids, I drive more cautiously and immediately pay attention to abnormal tire pressure warnings. Abnormal tire pressure is most common, such as slow leaks or pressure drops due to temperature changes; faulty sensors may also trigger false alarms. Use a pressure gauge to check each tire's pressure individually, and address low pressure to prevent blowouts. Sensors have a limited lifespan, and older cars have higher failure rates. Before heading out with the family, ensure tire pressure is normal—getting a comprehensive check at a repair shop offers extra peace of mind. Don’t panic over frequent cold-weather warnings; simply add air. Ignoring this poses significant risks and can easily lead to accidents. Safe driving starts with attention to detail.
