TPMS stands for Tire Pressure Monitoring System. It is a safety feature that has been mandated in all new vehicles since 2007. The system monitors the air pressure in the tires and alerts the driver if the pressure drops below a certain level. This is important because driving on under-inflated tires can be dangerous and cause a blowout.
How Does TPMS Work?
There are two types of TPMS: direct and indirect. Direct TPMS uses sensors mounted inside the tire to measure the pressure and temperature of the air inside. Indirect TPMS uses the wheel speed sensors already present in the vehicle to determine if a tire is under-inflated. The system will then alert the driver via a dashboard warning light if the pressure drops below a certain level.
Direct TPMS is more accurate than indirect TPMS because it measures the actual pressure inside the tire. However, it can be more expensive to install and maintain because it requires sensors inside each tire. Indirect TPMS is less expensive to install and maintain, but it is not as accurate as direct TPMS.
Why is TPMS Important?
Driving on under-inflated tires can be dangerous. It can cause the tire to overheat and potentially lead to a blowout. Under-inflated tires also reduce fuel efficiency and cause the tires to wear out faster. In addition, properly inflated tires provide better traction and handling, which can improve overall safety.
TPMS helps ensure that your tires are properly inflated, which can improve your safety on the road. It also helps you save money on fuel and tire replacement costs in the long run.
How to Maintain TPMS?
Like any other system in your car, TPMS requires maintenance. Here are some tips to keep your TPMS functioning properly:
1. Check Your Tire Pressure Regularly
TPMS is not a substitute for manually checking your tire pressure. You should check your tire pressure at least once a month and before long trips. Use a tire pressure gauge to ensure that your tires are properly inflated.
2. Replace Dead TPMS Sensors
TPMS sensors have a battery life of about 5-10 years. If a sensor dies, it will need to be replaced. Your mechanic can replace the sensor for you.
3. Reset Your TPMS
If you rotate your tires or replace them, you will need to reset your TPMS. Your car's owner manual will have instructions on how to do this.
Conclusion
TPMS is an important safety feature in modern cars. It monitors your tire pressure and alerts you if it drops below a certain level. Properly inflated tires improve your safety on the road and help you save money on fuel and tire replacement costs. Maintain your TPMS by checking your tire pressure regularly, replacing dead sensors, and resetting the system when necessary.
