What Causes a Tire Pressure Monitoring System Malfunction?

[KatherineAnn]

The reasons for a tire pressure monitoring system malfunction are: 1. Punctured tire; 2. Prolonged driving or failure to replenish tire pressure in time; 3. Faulty tire pressure sensor; 4. Failure to reset the tire pressure module after tire replacement or repair. The functions of the tire pressure monitoring system are: preventing accidents, prolonging tire service life, and reducing wear on the suspension system. The methods to address a tire pressure monitoring system malfunction are: 1. Display the tire pressure and temperature readings on the dashboard to check for abnormalities; 2. Inspect the underinflated tire for air leaks; 3. Check if the tire pressure monitor is faulty.

I've been driving for almost 15 years and have encountered tire pressure monitoring system (TPMS) failures several times. The main reason is usually that the sensor battery has reached the end of its lifespan—they typically last about seven or eight years before giving out. Daily driving vibrations or hitting potholes can easily damage them. If you forget to recalibrate the system after getting new tires, it may trigger false alarms. Large temperature differences between winter and summer, causing tire pressure to fluctuate, can also lead to frequent false warnings. Safe driving shouldn't rely on luck, so I make it a habit to manually check all tires with a pressure gauge every month to ensure accuracy. A tire blowout on the highway is extremely dangerous, especially on wet roads during rain. If the warning light comes on, pull over immediately to check—don't push through. I recommend checking the sensor condition during regular maintenance. Spending a bit to replace them can give you peace of mind on the road. Older cars are more prone to these issues, so don't wait until an accident happens to regret it—prevention is always the most reliable approach.

I'm a new driver with limited experience. Last time, the tire pressure monitoring alarm suddenly went off, which really startled me. After manually checking the tire pressure, everything seemed normal, but I learned several possible causes. Sensors can easily degrade over time—my used car was bought in 2010, so the battery might be nearing the end of its life. If the sensor's head gets damaged from rough roads or bumps, it may give false alerts. Once, after hitting a speed bump too hard, it stopped working properly. Sudden temperature changes can cause significant tire pressure fluctuations, leading the sensor to misread data. Restarting the car might temporarily turn off the warning light, but sometimes it comes back later. Safe driving is no trivial matter, especially when driving on suburban roads at night when it's harder to visually inspect tire conditions—extra caution is needed. I've learned to check the vehicle manual for reset procedures, and if that doesn’t work, I’ll take it to a professional at the dealership. As a novice, it’s unwise to stubbornly handle issues alone. Online forums suggest regularly checking tire pressure manually to catch potential problems early. Before driving with kids, I always inspect the car—a tire blowout is terrifying, and we can’t rely solely on electronic systems for unreliable alerts.

I have some knowledge about car parts. Tire pressure monitoring system (TPMS) failures are usually caused by the internal sensor battery running out, as they tend to fail after 5 to 10 years of service. Loose or corroded electrical connections can also interrupt signal transmission, and software bugs in the system's receiver module may cause false alarms after updates. It's recommended to manually verify with a simple tire pressure gauge instead of relying solely on the warning alerts. Safety comes first, and regular maintenance is key to preventing aging-related issues.
