How to Reset Tire Pressure Light

If you’ve inflated your tires and the tire pressure light doesn’t turn off, you’ll have to reset it. It’s important to remember that your tire pressure monitoring system (TPMS) should be always activated in order to ensure your safety. However, if the TPMS light stays on even after you’ve addressed the pressure issue, follow these simple steps to reset it, or bring your vehicle to the Triple J Guam service center near you to have our professional auto techs take a look at it.

Resetting Your Tire Pressure Light

The TPMS light should turn off once you’ve added the correct amount of air to your tires. In the event that it remains on, try these steps:

  • Drive the car for about 10 minutes at 50 mph. Often this will reset the sensor, and the next time you start the car the TPMS light should be off.
  • Turn the key to the “On” position without starting the car. Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and let it run for 20 minutes. This should reset the sensor. The tire pressure monitor reset button is usually located beneath the steering wheel. If you can’t find it, check your user’s manual.

These next two steps are a bit more involved, and are only recommended if you are comfortable with working on cars:

  • Inflate each tire to 3 PSI over the recommended amount, then deflate them completely. Make sure to do this with the spare tire as well, since it may also have a sensor. Once all tires have been deflated, reinflate them to the recommended tire pressure.
  • Turn the vehicle off, then open the hood and disconnect the positive battery cable. Turn the key to the “On” position and honk the horn for about three seconds to discharge any power still stored in the vehicle. Then reconnect the battery.

What Does a Flashing Tire Pressure Light Mean?

If your tire pressure light is flashing, it could be a sign that either the sensor battery needs to be replaced, or that one of the sensors is malfunctioning. With a flashing or blinking TPMS light, it’s best to schedule service at Triple J Guam in Tamuning to have our technicians diagnose exactly what the problem is and take care of it for you.
