All you need to know about the Tire Pressure monitoring System TPMS and the importance of TPMS light flashing & reason, how it works and reset, When the indicator light symbol shown and in which countries it is mandatory compliance for all new models.

What does TPMS means?

TPMS stands for Tire Pressure Monitoring System. It is a safety feature in modern vehicles that uses sensors to monitor the air pressure in each tire and alert the driver if the pressure drops below a certain level. This system helps to prevent accidents caused by underinflated tires, which can lead to poor handling, decreased fuel efficiency, and premature tire wear.

Why TPMS Light Flashing?

Reading a TPMS (Tire Pressure Monitoring System) typically involves checking the display or warning lights on your vehicle’s dashboard. Here are the general steps to follow:

Check if your vehicle has a TPMS warning light on the dashboard. This light usually looks like a yellow or red exclamation mark inside a tire-shaped symbol.

If the TPMS warning light is illuminated, it means that at least one tire’s pressure is below the recommended level.

Check the owner’s manual or the driver’s side door jamb to find the recommended tire pressure for your vehicle.

Use a tire pressure gauge to check the pressure in each tire.

Remove the valve cap from the tire and press the gauge onto the valve stem to get a reading.

Compare the tire pressure readings with the recommended pressure level.

If any tire’s pressure is below the recommended level, inflate it to the correct pressure.
After inflating the tire(s), drive the vehicle for a short distance (around 10 minutes) to allow the TPMS system to reset and re-check the tire pressures.

If the TPMS warning light is still on after inflating the tire(s) and driving for a short distance, it may indicate a problem with the TPMS system itself. In this case, it’s best to have a professional mechanic inspect and diagnose the issue.

How to reset TPMS – Step by Step

Check your vehicle’s owner’s manual to see if it has a TPMS reset button or if there is a specific way to reset the TPMS.

Make sure your tires are properly inflated to the recommended pressure.

Turn the ignition on, but do not start the engine.

Locate the TPMS reset button or reset procedure for your vehicle.

Press and hold the reset button or follow the reset procedure until the TPMS light blinks twice or you hear a beep.

Release the reset button or complete the reset procedure.
After resetting the TPMS, it may take a few minutes of driving for the system to recognize the new tire pressures. If the TPMS light stays on after resetting, there may be an issue with the system that requires further inspection.

How TPMS works?

TPMS works by using sensors to monitor the tire pressure and alert the driver if the pressure falls below a certain level.

Types of TPMS

There are two types of TPMS: direct and indirect.

Direct TPMS

This system uses pressure sensors mounted inside the tire, usually tire valve, which transmit information to a central computer usually called ECM or ECU in the vehicle. These sensors measure the tire pressure and send a signal to the computer, which alerts the driver if the pressure falls below a certain limit. Direct TPMS provides more accurate and precise readings, but can be more expensive to install and maintain.

Indirect TPMS

This system uses the ABS (anti-lock braking system) sensors to monitor the rotational speed of each tire. If one tire is significantly underinflated, it will have a shorter overall diameter and will rotate at a different speed as compared to the other tires. The ABS system detects this difference in tires rotational speed and alerts the driver that there may be a problem with tire pressure. Indirect TPMS is less expensive than direct TPMS, but it may not be as accurate or reliable. In both systems, if the pressure falls below the recommended level, a warning light appears on the dashboard speedometer, alerting the driver to check the tire pressure and inflate the tire as necessary.


TPMS or Tire Pressure Monitoring System is one of the important feature that are equipped in almost all the modern cars, due to regulations being enforced in many countries. Some time peoples have limited knowledge about the TPMS and its functionality and they become worried about the TPMS light flashing on their car panel. We have explained the TPMS light flashing and how to reset when needed. Moreover, you need to keep monitor your tires health and identify any issues if air leakage is frequent.
