What Causes Continuous Tire Pressure Alarm?
2 Answers
Common reasons for frequent tire pressure alarms include: 1. Tire replacement without resetting the tire pressure module; 2. Nail punctures causing changes in tire pressure; 3. Inflating tires without resetting the tire pressure monitoring system; 4. Prolonged vehicle inactivity leading to decreased tire pressure due to lack of inflation. The method to reset the tire pressure monitoring system is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle and hold down the tire pressure monitoring button; 4. After 5 seconds, an alarm sound will be heard, and releasing the button indicates a successful reset. The functions of tire pressure monitoring are: 1. Immediate alarm in case of rapid or slow air leakage when a tire is punctured; 2. Alert when tire loosening causes unbalanced friction, leading to high temperatures (up to 70°C) to prevent blowouts; 3. Warning when tire pressure falls below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts.
I find that the tire pressure warning frequently goes off, and the most common reason is a tire leak. The tire might have been punctured by a nail or debris, causing a slow leak and insufficient pressure; or the weather might have turned colder, causing the tire pressure to drop naturally and triggering a false alarm. Another possibility is a sensor malfunction, such as a dead battery in the sensor, poor wire contact, or a system calibration error. As a seasoned long-distance driver, I've encountered this many times. Whenever the alarm sounds, I immediately pull over and manually check each tire's pressure with a portable gauge—usually, the front tires are more prone to issues. Safety should never be overlooked, as low tire pressure can increase the risk of a blowout and fuel consumption. If something happens on the highway, it might be too late. My advice is to first go to a gas station to inflate and check the tires when the alarm goes off. If the problem persists, visit a repair shop to inspect the sensors and tire sealing—don’t delay to avoid potential hazards.
