"What is TPMS and How Does it Work ?"
Tire pressure monitoring systems (TPMS) are becoming an increasingly important safety feature in modern vehicles. TPMS technology helps drivers to maintain proper tire pressure levels, which can enhance vehicle performance, fuel efficiency, and overall safety. In this blog post, we'll take a closer look at what TPMS is, how it works, and why it's important for drivers to have in their vehicles.
What is TPMS?
TPMS is a system that monitors the tire pressure levels of a vehicle and alerts the driver if the pressure drops below a certain threshold. There are two types of TPMS systems - direct and indirect.
Direct TPMS: This type of system uses sensors that are mounted inside each tire to monitor the pressure levels. The sensors transmit data to the vehicle's onboard computer, which then alerts the driver if the pressure drops below a certain threshold.
Indirect TPMS: This type of system uses the vehicle's anti-lock braking system (ABS) to monitor the speed of each tire. If one tire is rotating at a different speed than the others, it indicates that the pressure level is low. This information is then relayed to the vehicle's onboard computer, which alerts the driver.
How Does TPMS Work?
Direct TPMS:
The direct TPMS system uses pressure sensors that are mounted inside each tire to monitor the pressure levels. These sensors can be either mounted to the valve stem or built into the tire itself. The sensors transmit data to the vehicle's onboard computer, which then alerts the driver if the pressure drops below a certain threshold.
The pressure sensors work by detecting changes in air pressure inside the tire. When the tire pressure drops below the recommended level, the sensor sends a signal to the onboard computer. The computer then illuminates a warning light on the dashboard to alert the driver.
Indirect TPMS:
The indirect TPMS system uses the vehicle's anti-lock braking system (ABS) to monitor the speed of each tire. If one tire is rotating at a different speed than the others, it indicates that the pressure level is low. This information is then relayed to the vehicle's onboard computer, which alerts the driver.
The ABS system works by using sensors that are mounted at each wheel. The sensors detect the rotational speed of each tire and send the information to the vehicle's onboard computer. If one tire is rotating at a different speed than the others, it indicates that the pressure level is low.
Why is TPMS Important?
TPMS is important for a number of reasons, including:
Safety: Proper tire pressure is critical for safe vehicle operation. Underinflated tires can lead to poor handling, reduced braking performance, and increased risk of a blowout or tire failure.
Performance: Proper tire pressure can enhance vehicle performance by improving handling, reducing tire wear, and increasing fuel efficiency.
Cost savings: Maintaining proper tire pressure can help to extend the life of your tires, which can save you money in the long run. Additionally, proper tire pressure can increase fuel efficiency, which can save you money at the gas pump.
Environmentally friendly: Proper tire pressure can reduce your vehicle's impact on the environment by reducing emissions and improving fuel efficiency.
TPMS Tips and Maintenance:
To ensure that your TPMS is functioning properly, it's important to follow some basic tips and perform regular maintenance:
Check your tire pressure regularly: Even with a TPMS system, it's still important to check your tire pressure regularly. This can be done with a tire pressure gauge, which can be purchased at most auto parts stores.
Follow the manufacturer's recommendations: Be sure to follow the manufacturer's recommendations for tire pressure, which can typically be found in your vehicle's owner's manual or on the driver's side door jamb.
Check your TPMS warning light: If your TPMS warning light comes on, it's important to check your tire pressure and inflate any tires that are underinflated.
Replace faulty sensors: If your TPMS system is not functioning properly, it may be due to a faulty sensor. Be sure to have any faulty sensors replaced by a qualified technician.
Conclusion:
Tire pressure monitoring systems (TPMS) are an important safety feature that can help drivers maintain proper tire pressure and ensure that their vehicle is operating at its best. By using a TPMS system, drivers can improve their vehicle's safety, performance, and fuel efficiency while also reducing their impact on the environment. With proper maintenance and regular checks, TPMS can provide drivers with peace of mind and help to prevent costly tire-related issues.
