1. Common Cause of TPMS Light: Low Tire Pressure
The most straightforward reason for a TPMS warning is low tire pressure. Tires naturally lose a small amount of air over time, and things like rough roads or overloading your vehicle can accelerate this process. If the pressure drops below the manufacturer’s recommended level, the TPMS light will pop on to let you know.
Driving on underinflated tires isn’t just bad for fuel economy; it can lead to uneven tire wear and reduce your ability to brake and steer effectively. Regularly checking your tire pressure with a reliable gauge can help you avoid this common issue.
2. Temperature Changes
When the temperature drops, so does tire pressure. This is because the cold air inside your tires contracts, taking up less space. In fact, for every 10°F drop in temperature, your tire pressure decreases by about 1 PSI (pound per square inch). That means chilly mornings or a sudden cold front can easily trigger the TPMS light, even if your tires were properly inflated the day before.
Once the day warms up or you add air to your tires, the light may go off—until the next cold snap, of course. But in some cases, low tire pressure may indicate an underlying issue, such as a slow leak or tire damage. That’s why it’s important to monitor your tire pressure regularly and pay close attention to what your TPMS light is trying to tell you.
3. TPMS Sensor Malfunction or Failure
Sometimes, the culprit isn’t your tires—it’s the TPMS itself. The system relies on sensors inside your wheels to monitor air pressure, and these sensors can wear out or fail over time. It could be that one or multiple sensors were damaged from everyday road hazards, a battery failure, or other sensor malfunction.
If the TPMS light stays on even after you’ve checked and adjusted your tire pressure, it’s time to bring your vehicle in for service. Our ASE-certified professionals at AutoPro can perform further diagnostics to get to the root of any sensor issue and can tackle even the most complex repairs.
4. Tire Damage Can Trigger the TMPS Light
Your Tire Pressure Monitoring System (TPMS) light is like a helpful passenger that doesn’t hesitate to point out an issue with your tires. It may come on if one of your tires has a puncture, cut, or other damage from potholes or a collision. Even minor damage can cause a slow leak, leading to gradual air loss and reduced performance.
Driving on a damaged tire isn’t just inconvenient—it’s dangerous. If you suspect a puncture or other issue, have your tire inspected and repaired (or replaced) as soon as possible.
5. Recent Tire Service May Require TPMS Reset
Did you recently have your tires rotated or replaced? If so, the TPMS sensors may need to be reset. Recalibration is a quick process, but it’s essential to ensure your TPMS continues to provide accurate readings. If you’re in the Hennepin County area, AutoPro Auto Service can take care of this for you in no time.
