Why is Your Tire Pressure Light On?

To be straight, your tire pressure light will be on because the tire pressure of your tires is low. The TPMS might be on immediately when you start your car, or it might come on suddenly during a drive. Your tire pressure might be low because of two major reasons:

Weather/Temperature Changes

When the temperature decreases abruptly, the pressure in the tires tends to decrease as well. You ought to check your tire pressure as often as you can. If you haven't been doing so, sudden weather changes can reduce the pressure in more than one tire. This can cause a significant difference, which might activate the tire pressure light.

A leak or a puncture in your tires

Once there is a hole in your tire, it loses air. The pressure is thereby reduced, and your tire becomes flat. If you have a short distance to cover, you can top it up and keep it moving as slowly as possible. If it is a long way to go, you should try replacing it with a spare tire.

What Does It Mean When the TPMS Light is Flashing?

The TPMS uses a battery. Like all devices that use batteries, the battery is going to get weaker as you continue to use it and will eventually die. A low battery might cause the TPMS light to flash in an irregular manner. This goes without saying that when the TPMS light is flashing, the TPMS battery might need to be replaced.

Another factor that might cause the TPMS light to flash is when there is a problem with one of the sensors. You can confirm this by consulting a professional.
