Tech 1 Auto's car, vehicle and tire blog

Our blog gives you tips and helpful information from the motoring industry regarding vehicle and tire maintenance and repair.


That funny looking light is very important to the safe operation of your vehicle and it shouldn’t be ignored. The light is part of the Tire Pressure Monitoring System (TPMS) that will illuminate if there is a problem with the system. Most vehicles today are equipped with sensors that are mounted in the wheels that transmit tire pressure to a computer in the car via radio waves. There are some vehicles that will have a TPMS sensor mounted in the spare tire. Other vehicles use wheel speed sensors to determine if a tire is under inflated.

If the light comes on and stays on one or more of your tires may have a low pressure condition. If driving, you should pull over and stop in an area where you can safely inspect your tires to see if they look under inflated. If you have a flat tire, have your spare tire put on. If the tires look low or look OK, drive to a shop that can inspect and adjust your tire pressures. Don’t forget to have the spare tire checked. As we have said before, a low tire will overheat which can lead to a failure of the tire.

If the TPMS light comes on and flashes, this indicates a malfunction in the system itself. Take your vehicle to the repair shop and have the problem diagnosed, then repaired.
