Why is Your TPMS Light On in your Car?

When your TPMS light or TPMS light blinks, it is a bad sign. This shows that there is something wrong with the tire. Keep in mind that this could also be a fault in the sensor. However, the problem could in fact be a lot worse.

Either way, you have got to deal with it. Fortunately, addressing a TPMS light is usually very simple. Below, you will find out about different ways you can get your tire light to shut off. Not to mention, some of the best fixes for tire light problems do not cost you a single penny, or require any tools.

Your Tire Needs Air

Adding air to a tire involves blowing air into the valve stem. Behind the valve stem, you will find an electronic sensor that is self contained. All these sensors do is monitor tire pressure and report back to the car’s computer if the pressure is lower that the optimum limit. This signal triggers the rounded exclamation light that you see in the speedometer.

If there is anything going on in the tire that triggers the light, this means that something is wrong. Majority of the times, the light blinks because you have set the wrong tire pressure. If you live in a colder climate, you will note that the tire light will often come on when the temperature drops. This does not make any difference because it means that the pressure is wrong.

You want to therefore open the driver’s door and look for the label. On this label aligned with the door, you will find the exact tire pressure of your car. The air pressure requirements also differ according to each tire.

When to Check your Tire Pressure?

You want to make sure that you check the tire pressure before you have driven your car at all. Preferably, you want to check it when the tire is cold. If you need to drive somewhere to adjust your tires, you want to make sure that it is your first stop so that you have driven as little as possible. This way the tire temperature does not heat up.

It is also important to check the tire pressure of all the four tires. You want to start at the first tire, and go tire to tire to set the pressure correctly until you are done with all four tires. Do not skip this step because if you do, then the light will stay on.

When checking the tire air pressure, do not forget about your spare tires. This is one of the biggest reasons why most car owners fail to get their tire pressure light to turn off. Many spare wheels come with TPMS sensors in them as well. Therefore, it can be the spare tire in your trunk that is triggering the light.
