As we enter 2023, it is essential to understand the various components of a car that make it run smoothly. One such component is the Tire Pressure Monitoring System (TPMS). This system plays a vital role in ensuring that your car's tires are in perfect condition, and it is essential to know how it works and what to do if it malfunctions. In this article, we will give you a detailed overview of TPMS, how it works, and its importance.
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. It is an electronic system that is designed to monitor the air pressure in your car's tires. The system uses sensors that are placed in each tire to measure the tire pressure. The sensors then send the information to the car's onboard computer, which alerts the driver if the tire pressure is too low or too high.
The TPMS system was introduced in the early 2000s to help drivers avoid accidents caused by tire blowouts. Low tire pressure can cause the tire to overheat, leading to a blowout, which can be dangerous, especially at high speeds. The TPMS system helps drivers detect low tire pressure before it becomes a significant problem.
How Does TPMS Work?
Direct TPMS
The TPMS system has two types: Direct TPMS and Indirect TPMS. Direct TPMS uses sensors that are mounted in each tire to measure the tire pressure. The sensors transmit the data wirelessly to the onboard computer, which displays the tire pressure on the dashboard. If the tire pressure is too low or too high, the driver will be alerted with a warning light on the dashboard.
Direct TPMS is more accurate than indirect TPMS since it measures the tire pressure directly. However, the sensors can be expensive to replace if they malfunction, and they can be affected by extreme temperatures.
Indirect TPMS
Indirect TPMS, on the other hand, uses the car's anti-lock brake system (ABS) to measure the tire pressure. The system uses the rotational speed of the wheels to determine if the tire pressure is low. If one tire is rotating at a different speed than the others, it could indicate that the tire pressure is low. The system then alerts the driver with a warning light on the dashboard.
Indirect TPMS is less expensive than direct TPMS since it does not require sensors in each tire. However, it is less accurate and can be affected by changing weather conditions, such as temperature and altitude.
Why is TPMS Important?
TPMS is crucial for several reasons. First, it helps drivers avoid accidents caused by tire blowouts. Low tire pressure can cause the tire to overheat, leading to a blowout, which can be dangerous, especially at high speeds. The TPMS system helps drivers detect low tire pressure before it becomes a significant problem.
Second, TPMS helps drivers save money on gas. Underinflated tires can reduce fuel efficiency by up to 3%. By keeping the tires properly inflated, drivers can save money on gas and help the environment by reducing carbon emissions.
What to Do if TPMS Malfunctions?
If your TPMS system malfunctions, it is essential to get it checked by a professional mechanic. The most common cause of TPMS malfunction is a dead sensor battery. The sensor batteries last between five to ten years, depending on usage. If the batteries are dead, the sensors will need to be replaced.
If the TPMS warning light comes on, it is essential to check the tire pressure manually. If the tire pressure is low, fill the tire with air to the recommended pressure. If the tire pressure is correct, it could indicate a malfunction in the TPMS system, and it should be checked by a professional mechanic.
Conclusion
In conclusion, TPMS is an essential component of your car's safety and performance. It helps you avoid accidents caused by tire blowouts and saves you money on gas. It is essential to understand how TPMS works and what to do if it malfunctions. If you notice any issues with your TPMS system, get it checked by a professional mechanic to ensure your safety on the road.
