How to Reset the Hyundai Tire Pressure Monitor System

April 4th, 2023 by

Among the other lights on your Hyundai’s dashboard, the tire pressure monitor system (TPMS) is a technology in newer vehicles that tracks the pressure in the tires and alerts you if it becomes dangerously low or high. By keeping an eye on the TPMS, you can keep your Hyundai’s tires inflated properly and in solid condition to keep you safe on the road. If the tire pressure falls below the recommended minimum, you’re more at risk of blowouts and poor handling.

If you’re reading this article, your vehicle’s TPMS light has likely come on, and you’re looking for a way to resolve the problem. Read below as our team at Allen Turner Hyundai in Pensacola, Florida, dives into the nitty-gritty of Hyundai’s TPMS and its functions and guides you on resetting it.

How Does Hyundai’s TPMS Work?

You should be able to see the tire pressure for each tire a few minutes into your drive as your car warms up. Typically, your car’s dashboard will display the PSI rating for each tire, sometimes including the spare tire, and will alert you if one falls outside of the recommended range (too low or too high).

How Do You Check the Tire Pressure?

Check each of the tires using a tire pressure gauge. If the gauge indicates that the PSI ratings are too low, refill them using an air compressor. You can find air compressors at gas stations around Pensacola, or you might have one at your home for easy access. If the tire pressure is too high on any tires, you’ll want to let some air out by deflating it until it has the appropriate PSI rating. There’s typically a small nub on the end of tire gauges; you can press this nub into the tire’s air valve to release air gradually.

Why Is the Sensor Light On or Flashing?

If the TPMS sensor light is on, your car is likely trying to alert you that the tire pressure needs attention. The dashboard often will indicate which tire is of concern and its current PSI rating. Most Hyundai vehicles’ tires should be within the 30-35 PSI range, but always check just inside your driver’s-side door to verify your vehicle’s requirements.

Tires naturally lose air throughout the changing seasons, losing pressure in the winter and gaining pressure in the summer. Reduced pressure may also indicate damage to the tire, such as a leak, that you’ll want to address as soon as possible. However, it’s also possible that the TPMS has a faulty sensor or other technical malfunction, which will appear as a flashing light showing that the system can’t process information properly. In this case, a certified technician should check to ensure everything is in order and guide you toward repairs if needed.

How Do You Reset the TPMS?

If the TPMS works as expected, it should automatically reset once you’ve restored the tires to their proper pressures and driven for a few minutes. However, if you’ve verified that the tires are all at the correct pressure and the TPMS indicator is still on after 10-15 miles of driving, you may need to reset the system to get it working correctly again. There are a few ways you can try resetting the TPMS yourself:

  • Hold down the reset button: Turn your vehicle on without starting the engine. Look for the TPMS reset button underneath the steering wheel. Hold it down until the TPMS lights flash three times, then restart your vehicle.
  • Reinflate the tires: Inflate each tire, including the spare, about 3 PSI more than the recommended maximum pressure. Then, deflate them until they are all flat. Finally, reinflate them to the correct pressure and drive your car for a few minutes to see if the light turns off.
  • Disconnect the battery: With your car turned off, carefully disconnect the positive cable from the battery. Turn the ignition on without starting the engine and honk the horn a few times to drain the car of power. Finally, reconnect the battery and see if the light has turned off once you restart your car.

What Should You Do if the System Doesn’t Reset?

If none of the DIY approaches do the trick or you’d rather leave your car in the hands of a technician, have a professional look at your vehicle to verify the condition of its TPMS and tires. If the TPMS is in less-than-ideal condition, professional mechanics can resolve the issue quickly and ensure your car leaves the lot in great shape.
