Tire Pressure Warning Light_216248072

Is the tire pressure light on after you’ve inflated your tires? If this is the case, you will likely need to reset it. Learn how to reset the tire pressure light right at home in the guide below from Robert Basil Cadillac. We’re here to help with all of your automotive questions and concerns near Hamburg and East Aurora. 



Resetting Your Tire Pressure Light

Once your tires have been properly inflated, the TPMS light should turn off automatically. However, that is not always the case. Learn how to reset a tire pressure light below. There are a few different methods you can try. 

  • Drive at or above 50 mph for 10 minutes to reset the sensor. The next time you start the car, the sensor should reset. 
  • When the vehicle is shut off, turn the key to the “On” position, but don’t start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to reset. In most vehicles, you will find that button under the steering wheel. If you are still not sure where to find it, this information should be in your owner’s manual. 
  • Inflate all tires to 3 PSI over their recommended amount before completely deflating them (Don’t forget the spare, as it may have a sensor). Then, reinflate them all to the correct tire pressure.
  • When the vehicle is off, you can disconnect the positive battery cable using a wrench. Turn the car on and honk the horn for approximately three seconds. This will discharge power that still remains stored in the car. Once this is done, the battery can be reconnected. 

What Does a Flashing Tire Pressure Light Mean?

Is there a flashing tire pressure light on your dashboard? Because tire pressure sensors typically use a battery, a flashing tire pressure light could be a sign that it’s time to replace that battery. However, a flashing tire pressure light is also a sign of an issue with the sensors. We recommend having the vehicle looked at by a technician to determine what’s causing the problem.
