When the tire pressure light comes on in a vehicle, it indicates that one or more tires are low on air. It can be caused by a slow leak in the tire or by driving over rough terrain that has caused the tire to lose some air. In this article, you get the detailed answer of why is my tire pressure lights on.

Check the air pressure in all tires if the light comes on and inflate them if necessary. Driving with low tire pressure can cause decreased fuel efficiency and handling problems. Let’s come to the tire pressure light blinking and the causes of why is my tire pressure light still on after filling the tires.

Why Is My Tire Pressure Light On

When the tire pressure light still appears after filling the tires, the system may need to be reset. There are a few ways to reset the system, but the most common is pressing and holding the tire pressure monitoring system (TPMS) reset button for about 10 seconds. The button is usually located on the dash or console. The owner’s manual for your car can help you find it if you are having trouble finding it.

There is usually a button on the dashboard or console for resetting the tire pressure monitoring system (TPMS). Once the system has been reset, it should turn off, and you can continue driving. It’s also possible that your tires are running low on air.

Causes Of Why Is My Tire Pressure Light Still On After Filling Tires

There are a few possible reasons why your tire pressure light is still on after you fill your tires.

  1.       The common cause is that the tire pressure sensor needs to be reset.
  2.       You’ll need to find the TPMS reset button, usually located in the glove box or the center console.
  3.       Once you’ve found the button, simply press and hold it for a few seconds until the light goes out.
  4.       Another possible cause of a tire pressure light that won’t turn off is a faulty sensor.
  5.       If this is the case, you’ll need a mechanic to have the sensor replaced.

What Should You Do If Your Tire Pressure Light Is On?

If you’re driving and your tire pressure light comes on, don’t panic. You can do a few things to reset the light and get back on the road.

  1.       Check your tires to ensure that they are properly inflated.
  2.       If they’re not, inflate them to the recommended PSI.
  3.       Inside the driver’s side door of the car, this data can usually be found.

If you don’t manage to deal with any of these issues, it’s recommended to take your motor vehicle to a garage for a tune-up. It could be less stressful to be secure than sorry when it comes to air tire pressures.

How Can You Prevent The Tire Pressure Light From Coming On?

Tire pressure monitoring systems (TPMS) alert you when your tires lose air pressure. Your tires are underinflated by 25% or more if the light comes on.

There are a few things you can do to prevent the TPMS light from coming on:

  1.       Check your tire pressure regularly.
  2.       If you live in an area with extreme temperatures, you should do this at least once a month and preferably more often.
  3.       Use a reliable gauge to check all four tire’s pressure, including the spare.
  4.       Add air to your tires if they’re low. Don’t wait until the TPMS comes on.
  5.       If you have to add a lot of air to one or more of your tires, have them checked by a professional.

The above steps will prevent why is my tire pressure light on.

Different Ways To Check The Tire Pressure

There are two ways to check tire pressure: with and without a Tire Pressure Monitoring System (TPMS). With a TPMS, you can check the tire pressure by pressing a button on the dash. Without a TPMS, you’ll need to use a gauge to check the pressure.

If your tires are underinflated, add air until they are properly inflated. Your car’s owner’s manual or the placard inside the driver’s door will provide this information.

Importance Of TPMS Reset Button

The TPMS reset button is important to your car’s safety system. Knowing where the reset button is on your tire pressure light will help you fix it if it comes on.

Your car’s TPMS system monitors the air pressure and alerts you when it gets too low. If you have a flat tire or a slow leak, the TPMS light will come on. In most vehicles, you can find the reset button near the steering wheel, on the dash, or in the glove box.

The reset button turns off the TPMS light and resets the system. It’s important to do this so you can avoid driving on underinflated tires. Underinflated tires can cause blowouts, poor handling, and decreased fuel efficiency.


The tire pressure light illuminates when the tire pressure in one or more tires is low. The light usually comes on when the car is started, and it should go off after a few minutes of driving. The light will stay on if the tire pressure is still low and needs to be checked.

I hope this article answered your question about what that tire pressure light means and why is my tire pressure light on.
