Important Things to Remember about TPMS

Important Things to Remember about TPMS


It was indeed noted that if your vehicle was built after year 2007, it will be installed with a TPMS sensor which would light up once there is an indicated issue with the tire inflation.

The sensor will light once the equipment detected that the pressure on one of the tires installed in your car is less than the car’s suggested pressure level by 25% or even more than. Once the exclamation mark in yellow colour inside a tire-cross area lighted into your dashboard, it is time for you to check the tires and do necessary actions to ensure a safe and hassle-free drive. You must check your tires immediately as it may have low tire pressure and multiple punctures.




If you know how to deal and use your TPMS sensor, you would be worry-free, as it gives you an advantage of knowing when to check your tires before it causes any problem. This will make car owners avoid a small instance of puncture or cut to cause an even larger issue on the road. Punctures from road surfaces and sudden under inflation because of the temperature are just some of the main problems that you could avoid if you know how to react when the TPMS sensor illuminated. Making sure that you know what to do when this lighted up will result into a longer lifespan of the tires, efficiency in fuel use, and security of you and your loved ones when driving.


TPMS sensors come in two types and they are called direct and indirect. Each type would let you monitor the tire pressure, but using different procedures involved. Direct TPMS sensor will identify the pressure directly in the wheels attached, while Indirect TPMS sensor would base its measurement on the tire’s speed when rotating.

Direct TPMS

It is a sensor operated with the use of batteries inside the vehicle’s wheel. Once it detected that there is an issue with the tire pressure, it transmit signals to the vehicle and light up your dashboard for warning. As it gives you the warning once the tire pressure is 25 % lower than the suggested pressure amount, it makes it more reliable when using these sensors on your vehicle, than indirect sensors available in the market. There are even some advanced systems that will let you check individual tires in your vehicle.

Indirect TPMS

The indirect TPMS sensors are using speed detectors of your car’s wheels. The sensors would measure the rotational speed of all tires attached in the vehicle. This is used to identify which wheels are not rotating fast enough than the other wheels installed. It gives you a warning based on how it would detect the speed of the wheels installed in your vehicle. Car manufacturers provide indirect TPMS to follow federal guidelines, at the same time reducing the cost of the vehicle. This system is cheaper as it already uses the current components in the vehicle, but they also have some disadvantages. This type of TPMS could not inform you as to which of the tires are meant to be checked and needs proper inflation. This may cause additional check to know which one needs adjustment on the pressure or tire change.

TPMS Sensor Batteries

TPMS batteries mostly last for 7-10 years of lifespan. Once it goes faulty and weak, remember that they are not detachable and would let you replace your sensors with a brand new one.

TPMS sensors compared to Tire Pressure Inspection

TPMS sensors determine the right pressure of your tires to avoid bigger issues, but it should not replace your monthly tires check-up. Remember that the sensors would only give you a warning if the tires seem like under inflated by 25% or more, which is a high number to consider already. It is mentioned because once your tires are under inflated by 5%, it already start causing issues that may cause bigger trouble so having it checked manually is still a must for all vehicles. Remember that having TPMS installed is just an additional measure but should not be a replacement to the existing routines or checks you have for your tire’s maintenance.
