![]() This is the most expensive system that allows you to actively monitor your tire pressure. ![]() You know that a car has a high line system if you can view the PSI of each tire somewhere on the dashboard. Each sensor will have a unique indicator, so you’ll know the current pressure of your tires. The high line system will periodically receive information from the electronic gauges on your tires while the vehicle is running. If one or more of the tires has tire pressure below the recommended amount for your tires, your car’s computer will detect the discrepancy and activate the warning light.Īll dTPMS will have gauges attached to your rims, however the way that the system extrapolates the data is dependent on whether you have a High Line or Low Line System.Ī high line system will have an active monitor for the individual pressures of each of your tires. Direct TPMS (dTPMS)Ī direct TPMS will have an electronic pressure gauge sensor on the rims of all four of your tires. If your TPMS light is flashing, that indicates a problem with the TPMS system, so it's time to visit the dealership. Usually, it means one or more tires is at least 25% below the recommended tire pressure. If your TPMS light is solid, that indicates an issue with your tire. So, what’s the difference? Flashing vs solid TPMS However, depending on your vehicle, you may have a Direct TPMS or an Indirect TPMS. This doesn’t always mean your tire has a leak or puncture, as it may have lost pressure over time to the point where the system has detected an issue. If the TPMS icon lights up, that means that an electronic system connected to your tires has detected a discrepancy in your tire pressure. In this article, we’ll be going through everything there is to know about a TPMS, so you know what it means when that little icon lights up. Because it’s considered a key safety feature, TPMS has been mandatory for all passenger vehicles in the US since 2008.Ī TPMS can function in a few different ways, and it’s important to know how your TPMS works, so you’re aware of how to maintain it and, in some situations, why it may not detect tire pressure loss. This electronic system is designed to prevent accidents by notifying the driver when a tire or tires needs air. This icon means that your Tire Pressure Monitor System, or TPMS, has sensed that one or more of your tires has air pressure (measured in PSI) below the recommended amount. If you have a car built during or after 2008, you may have seen this icon pop up on your dashboard. What should you know before change a tire wtih TPMS?. ![]()
