Learn how to reset the TPMS on your Hyundai HB20. Step-by-step guide for 2012–2026 models, including button location, infotainment reset, and troubleshooting tips.

Last Updated: June 27, 2026

Quick Answer: Resetting the TPMS on a Hyundai HB20

To reset the TPMS on a Hyundai HB20, first inflate all tires to the pressure shown on the driver’s door jamb label (typically 32–35 psi). Turn the ignition to ON (without starting the engine), then locate the TPMS reset button under the steering column or in the glove box. Press and hold the button until the TPMS indicator blinks three times and release. Finally, drive the vehicle at 50–80 km/h for 10–15 minutes to complete the calibration. If the light remains on, inspect each tire’s pressure or check for a faulty sensor.

Understanding Your Hyundai HB20’s TPMS

What Is TPMS and Why Does It Need Resetting?

The Tire Pressure Monitoring System (TPMS) on your Hyundai HB20 is a direct system – meaning each wheel houses a dedicated sensor that measures actual air pressure and transmits that data to the car’s computer. This is different from indirect systems that rely on wheel speed sensors. When you rotate tires, replace a sensor, or simply adjust pressures after a seasonal change, the system expects a recalibration to reset its baseline. Without a reset, the TPMS warning light may stay illuminated even if pressures are correct, leading to unnecessary worry.

Common triggers for a reset include:

Tire rotation
Installing new tires or sensors
Adjusting pressure from winter to summer settings
After a low-pressure warning has been resolved

Where Is the TPMS Reset Button Located?

Hyundai changed the reset method over the HB20’s production years, so knowing your model’s year helps.

2012–2019 models: The physical TPMS reset button is usually located under the dashboard, near the steering column close to the fuse box. In some trims it is inside the glove box. Look for a small button labeled “TPMS” or with a tire-and-exclamation‑mark icon.
2020+ models: Many newer HB20 trims integrate the reset into the infotainment system. Go to Settings → Vehicle → TPMS → Reset and confirm on the touchscreen.
No button or menu visible? Some base trims auto-reset after driving at highway speeds for 15–20 minutes. Your owner’s manual will specify which system your car has.

A common mistake first-time owners make is hunting for a button that doesn’t exist on a 2021 model. When in doubt, check the manual or look for a digital reset option.

Step-by-Step TPMS Reset Procedure

Step 1: Check and Adjust Tire Pressures

Before you attempt any electronic reset, verify that all four tires (and the spare if it has a sensor) are inflated to the recommended values. The correct pressure is printed on a sticker inside the driver’s door jamb – usually between 32–35 psi (220–240 kPa). Using a reliable gauge is essential; gas station gauges can be inaccurate.

Measure each tire when cold (car hasn’t been driven for at least three hours) for the most accurate reading.
Inflate or deflate as needed.
Wait about 10 minutes after adjusting so the sensors can register the new pressures.

Step 2: Enter Reset Mode

You have three scenarios depending on your HB20’s equipment.

With a physical button:

Turn the ignition to the ON position (the engine should not be running).
Press and hold the TPMS button for 3–5 seconds.
The TPMS warning light will blink three times and then turn off – release the button. The system is now in learning mode.

With an infotainment system:

Ensure the vehicle is parked and the ignition is ON.
Navigate to Settings → Vehicle → TPMS → Reset.
Confirm by pressing “Reset” or “Yes.” The screen will usually show a confirmation message.

For models without a button or menu (auto‑reset):
Simply begin driving. The system will attempt to learn the sensor IDs and pressures as you drive. No manual step is needed.

Step 3: Drive to Complete Calibration

The reset procedure isn’t finished until the car has been driven long enough for the sensors to transmit data. Drive the HB20 smoothly – avoid hard corners, sudden braking, or rough roads – for 10–15 minutes at speeds between 50–80 km/h (30–50 mph). This allows the onboard computer to collect signals from each wheel’s sensor.

If the TPMS light turns off after this drive, the reset succeeded.
If the light continues to flash, the system is still learning. Continue driving for another 5–10 minutes.
If the light stays on solid, move to troubleshooting.

Troubleshooting TPMS Reset Failures

Sometimes the reset doesn’t take, and the TPMS light remains stubbornly on. Use this table to diagnose common issues.

Symptom	Possible Cause	Solution
Light stays on after reset	One tire still low pressure	Re‑check and re‑inflate all tires
Light blinks for 1 min then stays on	Sensor fault, dead battery, or lost communication	Visit a tire shop for sensor diagnostics
Button does not respond	Blown TPMS fuse or faulty button	Check the interior fuse box for TPMS fuse
Infotainment reset grayed out	Vehicle in motion	Stop, turn ignition OFF, then back ON while parked
Light returns after a few km	New sensor not programmed into system	Relearn all sensor IDs with a TPMS tool or dealer
Light comes on only after driving	Pressure increased from heat, but one tire is borderline	Check pressure again when cold

When to Use a TPMS Relearn Tool

If you’ve replaced one or more sensors, the HB20’s computer needs to “learn” the new sensor IDs. The manual reset procedure (button or menu) only works if all sensors are already known. A dedicated TPMS relearn tool (often called a trigger tool) sends a signal to the sensor to wake it up and transmit its ID. Many auto parts stores can perform this for free, or you can buy a universal tool for around $30–50. If you skip this step, the TPMS light may turn off initially but return after a short drive.

Additional Context: TPMS Maintenance and Best Practices

Keeping your HB20’s TPMS in good shape saves you from false warnings and costly sensor replacements.

Sensor battery life: Each sensor contains a non‑replaceable battery that typically lasts 5–10 years. When you replace tires, consider replacing the sensors at the same time to avoid a sudden failure.
Seasonal pressure changes: For every 10°C drop in temperature, tire pressure decreases by about 1 psi. After a cold snap, the TPMS light may trigger even though no air has escaped. Simply adjust pressures and perform a reset.
Tire rotation: Always reset the TPMS after rotating tires. Otherwise, the system may report the wrong wheel location (e.g., left front instead of right rear) or show a false low‑pressure warning for a tire that was fine before.
Aftermarket wheels: If you install wheels that didn’t come with the original TPMS sensors, you may need to transfer the factory sensors or purchase new ones compatible with Hyundai’s system. Some aftermarket wheels require special valve stems.

Frequently Asked Questions (FAQ)

Do I need to reset TPMS after every tire pressure adjustment?
Only if the low‑pressure warning light was previously on. Minor adjustments of 1–2 psi usually don’t trigger a warning, so no reset is needed. But if you fix a slow leak that had triggered the light, a reset is required.

Will the TPMS reset work if I use aftermarket tires?
Yes, as long as the new tires fit properly and you reuse the original TPMS sensors. Aftermarket wheels without sensor provisions will cause a continuous warning unless you install functional sensors. New valve stems should also be compatible with the sensors.

How long does the HB20 TPMS reset take?
The button‑press or menu tap takes about 5 seconds. The driving calibration adds 10–20 minutes. Total active time is less than a minute.

Can I reset TPMS without driving?
No, the system needs wheel rotation to receive radio signals from the sensors. Some advanced scan tools can command the light off, but the sensors won’t be fully learned until the car moves. Driving is mandatory.

Why is my TPMS light on after replacing a flat tire with the spare?
The spare tire may not contain a TPMS sensor – many spares are bare steel rims without electronics. If it does have a sensor, it might have a different ID not yet registered. Drive for 10–15 minutes; if the light stays on, either the spare is sensorless or the system needs a relearn with a tool.

Is it safe to drive with the TPMS light on?
Yes, but you must check tire pressure manually as soon as possible. A steady light indicates one or more tires are underinflated. A flashing light (for about one minute at start‑up) indicates a system fault, such as a dead sensor. Driving long distances on underinflated tires can cause overheating, poor fuel economy, and blowouts.

Conclusion

Resetting the TPMS on a Hyundai HB20 is a straightforward task that any owner can handle in under 20 minutes. Start by verifying your tire pressures are correct, then follow the reset method that matches your model year – physical button, infotainment menu, or auto‑reset by driving. If the warning light persists, use the troubleshooting table to identify the issue, and consider a TPMS relearn tool if you’ve replaced any sensors. Regular maintenance – checking tire pressures monthly, resetting after rotations, and replacing sensors before their batteries die – will keep your HB20’s TPMS reliable and accurate.
