How to Reset the Tire Pressure Light (TPMS Reset Guide)

I'm Anthony Calhoun, ASE Master Tech. The TPMS light is the most common warning light I get asked about, and the reset process confuses people because it's different on every vehicle. Let me walk you through the universal approach that works on most cars, plus specific tips for the most popular brands.

Before You Reset — Check the Actual Pressure

Do not reset the light without checking your tire pressures first. The light is on because at least one tire is underinflated. Resetting it without fixing the pressure defeats the purpose of the system.

Here's what to do:

1. Find the correct pressure on the sticker inside the driver's door jamb. It will list front and rear pressures (they may be different).
2. Use a reliable tire pressure gauge to check all four tires plus the spare (if your spare has a TPMS sensor — many do).
3. Inflate any low tires to the specified pressure. Do not use the number on the tire sidewall — that's the maximum, not the target.

Three Reset Methods

Method 1: Drive It (Most Common)

After correcting all tire pressures, drive the vehicle for 10-20 minutes at speeds above 25 mph. Most TPMS systems automatically recognize the corrected pressures and turn the light off. This works on most Honda, Hyundai, Kia, Ford, Chevy, and Nissan vehicles.

Method 2: TPMS Reset Button

Some vehicles have a dedicated reset button. If you want a broader reference for vehicle maintenance and warning lights, APEX Tech Nation is a solid starting point built by working technicians.

Common vehicles with a reset button:

• Toyota/Lexus: Button below the steering column. Turn ignition to ON (don't start engine). Press and hold until the TPMS light flashes 3 times. Drive to complete the relearn.
• Some Hyundai/Kia: Settings menu in the instrument cluster. Navigate to TPMS and select reset.
• Some GM vehicles: Use the DIC (Driver Information Center) buttons to navigate to tire pressure and select relearn.

Method 3: Scan Tool Relearn

Some vehicles — especially after tire rotation — require a TPMS relearn tool or scan tool to match each sensor to its wheel position. The shop should do this during a tire rotation. If your light came on right after a rotation, go back and ask them to do the relearn.

Reset by Brand

Toyota/Lexus: Reset button under dash. Hold until light flashes 3x.

Honda/Acura: No button on most models. Correct pressures and drive 10-20 minutes. Some models use the infotainment system: Settings → Vehicle → TPMS Calibration.

Ford/Lincoln: Correct pressures and drive. Some models need the scan tool relearn.

Chevrolet/GMC: DIC controls → Tire Pressure → Press and hold checkmark until horn chirps.

Hyundai/Kia: Correct pressures and drive 15-20 minutes. Some newer models have settings menu reset.

Nissan/Infiniti: Correct pressures. Turn ignition ON. Press and hold TPMS button until light flashes. Drive to complete.

BMW/Mercedes: Reset through the iDrive or MBUX infotainment system under vehicle settings → tire pressure → reset.

Subaru: Correct pressures and drive. No manual reset — system auto-learns.

Why the Light Won't Turn Off

• One tire is still low. Double-check all four plus the spare with a known-good gauge.
• The TPMS sensor battery is dead. Sensor batteries last 5-10 years. Once dead, the sensor needs full replacement — it's sealed and the battery can't be replaced.
• The sensor was damaged during a tire change. Sensors are fragile. A careless tire tech can break the sensor valve stem or damage the sensor during mounting.
• The relearn wasn't done after rotation. The system doesn't know which sensor is at which wheel. It needs to be retaught.

When the Sensor Needs Replacement

If the TPMS light flashes for 60-90 seconds then stays solid, that usually indicates a sensor fault (not low pressure). The sensor itself has failed and needs replacement. Cost: $80-$200 per sensor installed, because the tire must be dismounted to access it.

Cold Weather and TPMS

Tire pressure drops about 1 PSI for every 10°F decrease in ambient temperature. If you filled your tires to 32 PSI during a 75°F afternoon and the next morning is 35°F, your tires are now at about 28 PSI — potentially low enough to trigger the TPMS light.

This is normal. Check and adjust your pressures when seasonal temperatures change significantly. Don't just reset the light — actually inflate the tires.
