What Does the TPMS Light Indicate?

The TPMS, or tire pressure monitoring system, is a sensory system in your vehicle intended to detect early signs of underinflated tire pressure. The TPMS light is one of your essential warning lights that can come on your dashboard. It is usually depicted with a horseshoe-like symbol with an exclamation point in the center. 

When the TPMS light comes on, it means that at least one of your tires is underinflated. It would be best if you pulled over to a safe location at your earliest convenience and manually measured your pressure with a gauge. 

 

How to Find the Right Pressure for Your Car

Tire pressure is measured in units of PSI or pound-force per square inch. To find the exact PSI that your tires need, you should look at the door jam. There, you will find a sticker with the pressures listed. You can also search for it in the owner's manual. 

When pumping air in your tires, make sure you do not overinflate them. Overinflated tires will result in poor traction and premature wear, as your tires are more inclined to wear in the center. Underinflation, on the other hand, will make your tires react poorly and decrease your fuel economy. You will see an outerwear pattern.

 

Flashing vs. Non-flashing TPMS Light

When your TPMS light pops up on your dash, you should be aware of the light's behavior.

  • If the TPMS light is solid or non-flashing, then one or more of your tires have lost at least 25% of their proper pressure.
  • If the TPMS light is flashing, there is a communication issue between the sensors and the car's computer system.
