To reset your tire pressure gauge (TPMS light), first ensure all tires—including the spare—are inflated to the PSI listed on the driver’s side door jamb. You can then reset the system using one of three methods: 1) Hold the “TPMS Set” button (found under the steering wheel or in the glove box) until the light flashes three times; 2) Navigate to “Vehicle Settings” > “Tire Pressure” on your touchscreen and select “Calibrate” or “Reset”; 3) Drive at speeds above 20-50 mph for 10 minutes to allow the system to relearn. If the light persists, a hard reset can be performed by disconnecting the vehicle’s battery for one minute.

Preparation Before Reset

Before hands-on any reset procedure, it is important to confirm that the tire pressure is really up to standard. Many car owners can’t turn off their lights simply because the air pressure is not right.

Find The Right Air Pressure Standard

Don’t stare at the “Max PSI” engraved on the side of the tire. That is the limit that the tire can withstand, not the pressure that makes you run daily. The correct cold tire pressure value is on the sticker on the door frame of the cab.

All-Round Inspection

It is necessary to ensure that the air pressure of the four main tires and the spare tire are completely consistent. The TPMS system is very sensitive. As long as one wheel is a little bit worse, it will often refuse to execute the reset command.

Method 1: Use The Physical TPMS Reset Button

Many models are equipped with a special “TPMS Set” physical button, which is the most direct way to communicate with the on-board computer.

Look For The Button

This thing is usually hidden quite deep, usually under the steering wheel near the knee, or in the glove compartment of the passenger car.

Operation Steps

Turn the ignition switch to the “On” position (power on but do not start the engine). Press and hold the reset button until the tire pressure indicator on the instrument panel flashes three times in a row.

Confirm

Release the button and start the vehicle to see if the yellow light has disappeared.

Method 2: Set Through The Car Large Screen

If your car is relatively new, equipped with a touch screen or digital instrument panel, then the reset program is usually already integrated in the software.

Menu Navigation

Use the steering wheel buttons or directly click the touch screen to enter the “Vehicle Settings” or “Settings ” menu.

Look For Tire Pressure Options

Rummage around and you’ll see sub-options like “Tire Pressure” or “TPMS Calibration.

Perform A Reset

Select Calibrate or Reset “. The system will usually pop up a confirmation box to tell you that the calibration process has begun.

Method 3: Driving To Recalibrate

Sometimes, the sensor needs to synchronize data with the vehicle’s ECU (Electronic Control Unit) through dynamic driving, which is what we often call “reset mode”.

Speed And Duration

Find a road with good road conditions and keep the speed above 20-50 mph.

Maintain Consistency

Drive steadily for at least 10 minutes, this is to leave enough time for the sensor to send updated data. As long as the computer confirms that the air pressure is stable, the warning light will naturally go out automatically.

Hard Reset

If all the above routine operations have been tried and the light is still stubbornly on, there is a high probability that there is an error code in the system. At this time, we have to use some rough means.

Disconnect The Battery

Open the engine cover and remove the negative (-) cable of the battery with a wrench.

Wait A Minute

Don’t rush to pick it back up, wait at least 1 the whole minute to completely discharge the capacitor in the circuit.

Reconnect

Connect the cable back and tighten. This “power-off method” can often force the TPMS system to restart and re-identify the current correct tire pressure. If this still fails, it may be that the hardware of the sensor itself is malfunctioning.
