What does it mean when the car detects pressure loss?
2 Answers
When the car's dashboard displays a detected pressure loss, it generally refers to tire pressure loss. Here is relevant information: 1. Tire pressure loss: The tire pressure monitoring system in the vehicle is designed to monitor the tire pressure status in real time. Some models do not have a tire pressure monitoring function and cannot display real-time tire pressure values, but most are equipped with a tire pressure warning system. Once the pressure in one or more tires changes, the tire pressure warning system will alert the driver. 2. Precautions: Avoid placing too many items in the trunk during daily use, and try not to store items there. An excessively heavy vehicle body can also cause the onboard computer to detect insufficient tire pressure, as the added weight reduces tire pressure. Prolonged exposure to this condition can eventually damage the tires.
When a car detects pressure loss, it usually indicates low tire pressure, as the Tire Pressure Monitoring System (TPMS) in modern vehicles is highly sensitive. I remember once when the warning light suddenly came on while driving, and it turned out to be a slow leak caused by a nail puncture. Sometimes, a sudden drop in temperature can also reduce tire pressure, triggering a false alarm from the sensor. It's important to pull over immediately and inspect the tires—use a flashlight to check for damage or measure the pressure with the onboard tire gauge. The standard values are listed on the label inside the door frame, typically ranging between 200 to 250 kPa. If the pressure is confirmed to be low, simply use an air pump to refill it. However, if the leak is rapid, calling for a tow truck or switching to the spare tire is necessary. Ignoring this issue is unsafe, as it can lead to uneven tire wear, increased fuel consumption, and greater risks on highways—especially in the event of a blowout, which can be disastrous. Developing a habit of regularly checking tire pressure can help prevent such situations.
