What Causes the Tire Pressure Monitor to Alarm?
4 Answers
The reasons for the tire pressure monitor alarm are: 1. The tire is punctured; 2. Prolonged driving or failure to replenish tire pressure in time; 3. Malfunction of the tire pressure sensor; 4. The tire pressure module was not reset after changing or repairing the tire. The functions of the tire pressure monitor are: preventing accidents, extending the service life of tires, and reducing wear on the suspension system. Methods to handle the tire pressure monitor alarm include: 1. Display the tire pressure and temperature on the instrument panel to observe if there are any abnormalities; 2. Check if the under-inflated tire is leaking; 3. Inspect whether the tire pressure monitor is malfunctioning.
As someone who has been driving for over a decade, I think the most common reason for a tire pressure monitoring system (TPMS) alarm is low tire pressure. This is often caused by a punctured tire slowly leaking air or gradual air loss. Weather changes also affect it—for example, tire pressure naturally drops when it gets cold in winter, and summer heat expansion may trigger alarms too. Another possibility is sensor malfunctions, like dead batteries or false system alerts. When I get an alarm, I immediately pull over to check, using a pressure gauge to measure. If all tires are normal, it might be a sensor issue, and I usually try restarting the system. Remember, low tire pressure increases fuel consumption, accelerates tire wear, and even raises the risk of a blowout. For safety, I check my tire pressure monthly to maintain stable levels, especially before long trips. Always inspect tires regularly for wear or foreign objects and address issues promptly.
With kids at home, I often drive them around, and a tire pressure monitor alarm can be really nerve-wracking. Most of the time, it's due to low pressure, possibly caused by sudden temperature changes—like moving from the garage to outdoors, where the temperature difference is significant. Or it could be due to tire aging with tiny cracks causing leaks. Other reasons include a dead sensor battery or occasional system false alarms. After the alarm goes off, I pull over in a safe spot and first check the tires for obvious leaks. If there aren't any, I use the onboard pressure gauge to measure and inflate to the recommended level. Don’t rush to reset the system—sometimes simply adding air fixes it. Ignoring this issue can make the car unstable, affect braking distance, and be especially dangerous in rainy weather. For my family's safety, I’ve made it a habit to check tire pressure every two weeks, being extra cautious during seasonal changes. Also, sensors in new cars are more sensitive and might trigger alarms over bumps—just add a bit of air and don’t worry too much.
I was quite panicked when I encountered the tire pressure monitoring system (TPMS) alarm for the first time shortly after buying my car. The reason could be low air pressure, possibly due to a small nail puncture causing a leak, or rapid pressure drop from cold weather. It might also be a sensor issue, like a dead battery or system malfunction. After the alarm went off, I pulled over in a safe spot to check the tires for any visible deflation. If there was no leak, I went to a service station to measure and refill the tire pressure. The standard values are usually listed on the inside of the fuel filler cap. I recommend that beginners avoid driving too long with low tire pressure and address it promptly, as it can affect vehicle balance and increase accident risks. Personally, I check my tires every season to avoid sudden alarms.
