What causes the tire pressure warning lamp (TPMS) to come on? What does a tire warning light do? What is Tire Pressure Monitoring System ?….?
TPMS (Tyre Pressure Monitoring System), alerts the driver when tire pressure becomes too low or too high due to unsafe driving conditions. While different car systems might monitor tire pressure differently but all have the same purpose. The driver might not be able to see if the tires are too low without this system. This can cause premature tire wear and even wheel failure.
Why does the tire pressure warning light come on?
When you turn the engine on, the TPMS indicator should light up for a few seconds. This allows you to inspect the system. If the light does’t come on, you have a problem with your tire pressure.
In such cases, it is a good idea to take the vehicle to the gas station to check the pressures of the tires and properly inflate them. Some systems can be quite responsive, and the light might stay on due to small PSI differences. Inflate your tires to the recommended tire pressures. For more information, refer to the owner’s guide or the tire decals located on the front doors. The light will stay on for a time after the tires have been properly inflated. When all the tires have been checked, the warning lamp will light up. If the warning light doesn’t go out, the problem is in the system. Some tire pressure sensors run on batteries. The battery lasts approximately 10 years. Low batteries cause the light to go on because it can’t communicate with the computer on board.
The TPMS light can sometimes turn on when temperatures change. The light may turn on when the ambient temperature drops at night. This is because tire pressures can drop and cause the light to go out. The temperature can increase during the day and while the vehicle is being driven, which will cause the tire pressures to increase and cause the light to go out. A tire that was inflated at 60 degrees may lose 3 PSI of pressure if it is dropped to 30 degrees. This is why it is important to check and fill the tires according to the technical specifications.
If the light flashes continuously for 60-90 seconds but then turns off every time you start your vehicle, it is likely that the TPMS has failed. Take the vehicle to a repair shop or service center and have the TPMS tested.
You should stop driving if the light turns on, and pull the car aside to check the tires. You can drive if the tires are still in good condition. You should check the tire pressure at the nearest station before you drive. Over-inflated tires can cause uneven tire wear, premature tire failure and premature tire wear. Properly inflated tires reduce friction and roll resistance, and increase water distribution. This will increase fuel economy and prolong the tire’s life. You should not ignore the warning light as the tires could become completely flattened.
