Tire Pressure Monitoring System


The TPMS or tire pressure monitoring system is a vehicle accessory that helps you keep your tires inflated to a safe level. It can help you avoid the cost and inconvenience of having a blowout, or worse, a complete tire failure. TPMS devices are typically battery-operated sensors that monitor inflation pressure and send data to your car’s central control unit.

When your tire pressure drops below the recommended level, the warning indicator will light up. It can also alert you to an active air leak, or an actual puncture. Depending on the model, the TPMS can also warn you of a low air temperature or other problem.

TPMS can be found on many vehicles today. Those that were manufactured after 2007 usually include the device as standard equipment.

Besides keeping your tires properly inflated, a TPMS can also be useful in reducing carbon monoxide emissions and lowering fuel consumption.

A TPMS is a good idea, but you should still perform regular manual tire checks. Depending on your car, the sensor will be located inside the tire, or on the rim. Regardless of where it is, it’s important to note that the sensor can wear out over time. In addition, TPMS devices can be damaged by curbs and other factors.

There are two main types of TPMS: indirect and direct. An indirect TPMS uses wheel speed sensors and other data to estimate tire pressures, while a direct TPMS uses dedicated sensors that measure the pressure directly. Both types use battery powered sensors that are designed to last for several years. Generally, the batteries for these sensors last 90 to 120,000 miles.

Direct TPMS uses individual sensors in each tire to transmit pressure information to the vehicle’s central control system. These systems can provide more accurate data than indirect TPMS systems, but they can be more expensive to install. They also require more attention, since they can be damaged by an accident or even a flat tire.

While a tire pressure monitoring system is not a substitute for regular maintenance, it can do a lot to help your tires last longer. And, it can reduce your fuel expenses, lower your CO2 emissions, and warn you of a potential problem.

Although there is not a universal standard for comparing different TPMS systems, there are some common elements. The light that alerts you to an under-inflated tire is the most popular example. This is a solid or blinking yellow symbol that resembles a cross-section of a tire. However, the light is part of a larger pressure monitoring system, so it can come on at odd times.

Tire pressure sensors are usually placed on the valve stem of each tire. Batteries power them, and their lifespan depends on how much you drive. As with other automotive components, your TPMS may require replacing a few times over the life of your tires. If you do decide to purchase a TPMS, be sure to take your time in choosing the right one.
