What is TPMS? How do I program a TPMS sensor? Tire pressure monitoring system

TPMS (Tire Pressure Monitoring System) is an automatic tire pressure monitoring system for your vehicle. It has been installed in new cars since 2015 and warns the driver of problems related to tire pressure. In this article, we’ll explain everything you need to know about the TPMS system: what it does, how to program it, and what it costs!

What is TPMS?

This automatic tire pressure monitoring system has become mandatory for all new vehicles since 2015. European Regulation No. 661/2009.

TMPS will play 3 key roles in your vehicle. First, you are guaranteed safety by maintaining good tire pressure while driving. Second, it allows you to save your Tires premature wear . Finally, this is the part environmentally responsible approach . In fact, good tire pressure reduces rolling resistance and therefore avoids excessive fuel consumption. fuel .

The TPMS system is a wheel sensor consisting of two parts:

  1. Sensors: this is the black plastic part of the sensor; the sensor battery needs to be changed every 5 years.
  2. Service kit : indicates all other system components, e.g. seal, core, nut and valve cap. Given the significant risk of corrosion and seal loss, it must be replaced every year.

TPMS system maintenance should be performed by a professional at a workshop. In fact, after the diagnosis, the sensor may need to be reprogrammed and the release must be carried out by the vehicle’s on-board computer.

Direct or Indirect TPMS?

Depending on the car model and make, the automatic tire pressure monitoring system can be direct or indirect. These two different systems have the following characteristics:

  • Direct TPMS : Tire pressure is calculated using several sensors placed inside the tires. If the pressure is too low or too high, a warning light will illuminate on the instrument panel to indicate which tire is affected.
  • Indirect TMPS system : In this system, tire pressure is calculated using anti-lock braking system and anti-lock braking system ( ABS et ESP ). The warning light on the instrument panel will also come on.

How to program a TPMS sensor?

If you have a TPMS sensor installed in your tires, there are several methods of programming it depending on the make and model of the vehicle. Thus, 3 different ways allow you to program the TPMS sensor to synchronize with the car:

  1. Manual training : After about ten minutes of driving, the vehicle can automatically read the sensors. After this time, the TPMS warning light will turn off. This system is used in, among others, Mercedes-Benz, Ford, Mazda and Volkswagen.
  2. Self-instructional : It is necessary to follow the exact activation procedure with many steps, such as starting, using the clutch in a specific order. This is especially true for Audi, BMW or Porsche.
  3. Onboard Diagnostic Interface Note: The OBD-II connector must be used to synchronize the system with the vehicle’s Onboard Diagnostic Interface. This method is found in Toyota, Nissan or Lexus.

How to disable TPMS sensor?

If your vehicle is equipped with a TPMS sensor, disabling it is strictly prohibited. . Indeed, it is equipment that guarantees your safety and reduces CO2 emissions.

In the event of a police check or during a technical inspection , it must be activated, otherwise you risk receiving a fine or refusal to pass the technical inspection.

What is the price of TPMS sensor?

If your vehicle was manufactured before 2015, it will not be equipped with a TPMS sensor. However, you can install it if you want to have this feature. Many models are sold in the car market and most often come in the form of kits.

So this kit is a Dash Receiver plus 4 gauges to fit inside each wheel with custom valve covers. To install it properly, it is best to hire a professional.

On average, a set will sell for between €50 and €130 across brands and models. It takes 1 hour to work. In total it will cost you between €75 and €230 .

The automatic tire pressure monitoring system is a very useful device to improve the safety of your vehicle. Maintaining good tire pressure is essential to ensuring the longevity of your tires and also helps ensure good traction!
