How To Reset The Hyundai Sonata Tire Pressure Sensor

Hyundai Sonata is a modern car model with the latest tech devices and settings. This allows people to drive comfortably while its modern signaling systems keep them updated about any warning or fault in the system. 

The tire pressure monitor system is also an integral part of modern cars, including Hyundai Sonata, allowing you to know the tire pressure status in the car tires. The tires must remain inflated to a specific pressure to keep the car safe and prevent damage to life and the car. 

Hyundai Sonata manual recommends a constant pressure of 34 PSI for the tires. The TPMS can find the tire pressure and indicate if it is too much or lower than the prescribed in any tire. 

The light of the TPMS goes on when it finds any discrepancy and then has to be rested after inflating the tires to the recommended pressure. Here are the simple steps to reset the TPMS in your Hyundai Sonata, but before that, you must know some more aspects about the same. 

Why should you reset the TPMS in your car?

The TPMS must be reset to the original reading after checking the tire pressure and inflating the tire. The system can reset automatically in many cars, and the warning light will go off.

That is not the case with the Hyundai Sonata, and the system may not revert to the original reading even after you have inflated the tires, and the warning light may also remain on. This means the sensor is not reading the tire pressure of newly inflated tires. This may also happen after tire change and rotation of tires.

The TPMS resetting will help it detect the tire pressure changes again and signal to the drivers. If the light is always on, they may not even check the tire pressure until it is too late and a major incident happens due to low tire pressure.  

TPMS light is a warning signal. 

TPMS can signal to the driver through a bright light on the dashboard. This may look like an exclamation mark with an inverted U-shaped light.

When it detects low or high tire pressure, the mark becomes bright red to warn you. The latest cars also indicate the tire- front/ back/ left/ right tire too. 

It would be best if you immediately reduced the speed of the car. Then stop at a safe place and get down. Check the tire pressure and refill using a portable air pressure machine if you have one or go to the nearest gas station/ service center.   

The process to reset the TPMS in Hyundai Sonata. 

Method one- Automatic reset

  1. Tire pressure plays a huge role in offering a good driving experience, so it is important to make sure the tires contain the right amount of pressure.  
  2. Drive for a few minutes at 50 miles per hour. 
  3. The TPMS should reset in ten minutes. 

If it fails, then it is time for a manual reset.   

Method two – Manual reset 

  1. Turn the car in the slot to on position but not start the engine.
  2. The TPMS button is either under the steering wheel or on its side in most cars.
  3. Press the reset button and keep holding it until the warning light blinks three times.
  4. Now release the reset button.
  5. You can always run the car engine for 20 mins and this should reset the sensor automatically.   
  6. Slowly allow the TPMS reset button to release.
  7. Once the sensor is switched off, then the light will also turn off 

Important aspects of Hyundai Sonata

You may not find a TPMS button in more recent models of Hyundai Sonata, and the system is supposed to take care of the rest on its own. For example, the latest models have an automatic system that will turn off the warning system after ten minutes of driving at 50 miles per hour in the last few years. 

Similarly, the new TPMS systems in the older models also may not be manually reset. But they will need to relearn the system in your car. The system must follow a few steps to relearn the new TPMS. 

  1. Fit new sensors in the car. Wait for 15 minutes. 
  2. The car manual has instructions that can help you put the car in the relearn mode. 
  3. Use the controls on the dashboard. 
  4. Use a scanner to scan the sensor and fill in the new details into the computer software in the car. 
  5. Confirm with the dealer/ mechanic about the correct ID. 
  6. Drive, approximately 20 minutes, for some time. The vehicle will recognize and authenticate the new ID, and then the sensor will be reset. 

TPMS Tips

TPMS or the tire pressure monitoring system in the car may be automatic. But even then, the car may have to relearn the new sensor system when it is changed.  

If the sensor system is automatic, you do not have to worry. But if it does not reset automatically, you must reset the warning system using the above tips. 

Conclusion 

The TPMS is an important warning system to detect and warn about the pressure in tires. The reset button is located within easy reach below the steering wheel. 

The TPMS must be reset every time you inflate the tires to optimum pressure. It may occur automatically after driving for a few minutes. But if it doesn’t reset, you must use this button to reset the system manually. 

Similarly, the TPMS must be reset when replacing the sensors with a new one. The steps must be followed meticulously to ensure that the system resets quickly. These steps are effortless to follow and you can reset the TPMS on your own.

If the system does not reset, it will remain on, and the warning light will stop bothering you. But you will never know when the tire pressure is not correct again. Reset the TPMS in your Hyundai Sonata and check tire pressure often.
