What Are Tire Pressure Sensors (TPMS) and How Do They Function?
Tire pressure sensors, commonly known as Tire Pressure Monitoring Systems (TPMS), are devices that monitor the air pressure inside tires. They alert drivers when tire pressure falls below a certain threshold, which can improve vehicle safety and efficiency.
- Types of Tire Pressure Monitoring Systems (TPMS):
– Direct TPMS
– Indirect TPMS
The two main types of Tire Pressure Monitoring Systems (TPMS) are direct TPMS and indirect TPMS.
- Direct TPMS:
Direct TPMS uses sensors mounted inside each tire to measure actual tire pressure. These sensors send real-time data to the vehicle’s onboard computer. According to NHTSA, direct TPMS provides accurate pressure readings, helping drivers diagnose issues promptly. For example, if a tire loses air, the system immediately alerts the driver, reducing the risk of blowouts.
Sensor batteries typically last around 5 to 10 years. However, they may require replacement if damaged or if the battery is depleted. Some manufacturers, like Toyota and Honda, have incorporated more advanced direct TPMS systems that can also report temperature changes within the tire.
- Indirect TPMS:
Indirect TPMS does not use physical sensors. Instead, it relies on the vehicle’s anti-lock braking system (ABS) wheel speed sensors to infer tire pressure changes. If a tire’s pressure is low, it has a smaller radius and rotates faster than the others. This information is processed by the vehicle’s computer to issue a warning. Though less accurate than direct TPMS, indirect systems are cheaper to implement and maintain.
The effectiveness of indirect TPMS can vary, particularly in vehicles driven primarily on smooth highways versus rough terrains. Critics argue that it does not provide real-time data and relies on the driver to monitor tire pressure regularly.
In summary, understanding the differences between direct and indirect TPMS can help vehicle owners make informed decisions regarding tire maintenance and safety.
