To ensure that your system is working correctly, you should have the TPMS sensor installed by a professional for the best results. Each TPMS sensor has a valve stem and valve core that are specific to it. It is important to make sure that any replacement of sensors has the correct parts. 

There are two types of TPMS sensors. The direct TPMS sensor measures the tire pressure from a sensor mounted inside your tire. Each sensor will relay an alert when the tire pressure dips below a certain percentage of the manufacturer's recommended air pressure. The second type of system is an indirect TPMS which uses your car’s anti lock brake system to measure the tire pressure. This measurement is based on the speed of rotation of the tires, which would be off if you had low tire pressure in one or more tires.

Yes. If your TPMS sensor is faulty, you can still drive your vehicle. However, you can’t rely on the vehicle to alert you if you have a tire pressure issue. The TPMS system is designed to notify the driver when there is low air pressure, and a faulty system will not be able to do so. If you do have a flat or slow leaking tire, you will need a tire pressure gauge to check the air pressure in the tires instead of relying on the TPMS.

The best way to check if your tire pressure sensor is faulty is to have it evaluated by a professional at a tire shop near you. Mavis can look at your TPMS sensor, assess any issues, and help you decide if you need new sensors or if the system just needs to relearn your sensors.
