When the Tire Pressure Monitoring System (TPMS) light comes on on your dashboard, it usually means that the air pressure in one or more of your tires has dropped below the expected level. The light can also be falsely activated by a faulty sensor, and it can also come on and go off randomly.
4 Reasons Why Your TPMS Light Is On But Your Tires Are Fine
If you have a TPMS light, it’s important to remember that it’s not a replacement for regular maintenance. While a TPMS light coming on can be a good warning of an impending emergency, there’s no substitute for physically checking your tires with a tire pressure gauge and topping them off as needed.
If you have a car with a TPMS, this means that each tire has a wireless sensor in it. Each sensor sends data to the computer, and the computer turns on the TPMS light if any of the sensors read a pressure that is higher or lower than the safe operating range.
The best thing to do when a TPMS light comes on is to manually check your tire pressure with a gauge. However, the light can also provide very important information if you know what to look for.
