TPMSIf you have your tire pressure light, or TPMS light flashing, then you can do a few things to turn it off. TPMS is an acronym for Tire Pressure Monitoring System. It pertains to a sensor located behind your tire gauge stem. If your tire is low on air, this sensor sends a wireless signal to the car’s computer. As soon as the car’s computer receives the signal, it triggers this light.

In September 2007, there was an act passed by the authorities that mandated all car manufacturers to install the cars in production with the TPMS light. This act was passed in response to the increasing accidents caused by driving underinflated tires. People soon began to realize how important it is to instantly address tire pressure problems for maximizing safety.

Adjust Air Pressure

The first thing that you want to check when you see this light is the air pressure. You want to make sure that all of your tires have proper air pressure. Sometimes the signal can be misleading. This is because they may show that a rear tire is underinflated, but in reality, it can actually be the front tire that you need to check.

This is because the tire position sensors are specific to each location of the car. You may have to change that if you rotate your tires. You want to make sure that all of your tires do have proper air in them.

Pressure Sensors Malfunction

You have tire pressure sensors inside your wheels. These sensors are battery operated, which means that you can expect them to go out if the battery happens to die. If you get different wheels on the car and you do not have them anymore, then this will cause the light to flash as well. Therefore, there can be many reasons why the light can be flashing in your car.

If you get brand new wheels, then the sensors inside the wheels will not match, and this can also become problematic. There is a tool that you can use to scan this problem. Ultimately, the problem can also occur if the sensors are not compatible to the particular tire. You have to therefore, take the wheel off of the rim to swap these out.


The best option is to replace the old sensors to the new ones and calibrating them. Resetting the tire pressure system will require professional help. As you can see, turning off the tire pressure light in your car can either simply require inflating the tires, or it can be a painstaking and costly replacement and calibration. The best way to find out is by inflating the tires and then checking whether the light turns off.
