How to Reset Your Tire Pressure Light At Home

TPMS stands for “Tire Pressure Monitoring System,” and it appears on your dashboard with a warning light whenever your car tires are irregularly inflated.

The TPMS light could indicate that your TPMS is not properly recalibrated or that your tire pressure is too low.

However, a lot of drivers complain that the TPMS warning light keeps blinking even after they inflated their tires to the proper tire pressure.

In this article, you will learn how to reset the TPMS light in several vehicles on the market.

Direct and Indirect TPMS

Before we move on to reset the TPMS system, it is important to understand your car’s type of monitoring system. There are 2 main types of TPMS: Direct and Indirect.

The direct TPMS has sensors located on the tire’s pressure valve or the rim. These sensors collect information and send it to the car’s onboard computer. However, the direct TPMS will most likely malfunction due to bad weather conditions. It is usually found in cars in the United States.

The indirect TPMS has sensors placed on the car’s ABS brakes and/or the speed sensors on each wheel. These sensors measure the wheel rotation speed and identify changes as underinflated tires rotate much faster compared to regularly filled tires. This system is most often found in cars in Europe.

Still unsure what’s wrong with your car? Ask a mechanic now.

How to Reset a Tire Pressure Light (TPMS)

Make Sure You Have the Correct Pressure

Before you try to reset your TPMS light, you should always ensure that you have the right tire pressure in your vehicle. Use a tire pressure gauge to check the tire pressure. Inflate each tire to its ideal PSI, then deflate the tires to zero. Then inflate again and drive for a couple of minutes at 15 mph to manually calibrate the sensors.

Use the Car’s TPMS Reset Button

Most cars with direct TPMS have a reset button located under the steering wheel through which you can conveniently re-calibrate the sensors. These buttons can be located in different places depending on the car model. Check your car owner’s manual. Put the key in the ignition and turn on the battery but don’t start the car. Push the reset button for about 3 seconds or until the system’s light starts blinking. Start the vehicle and drive for 20 to 25 minutes, then turn off the ignition. Some newer cars have this reset in the menu

Drive at 50 mph

This might be the easiest method, as it requires you to drive your car at 50 mph for about 10 miles. The sensors will automatically calibrate themselves after you have made sure that the tires have the right tire pressure. Some vehicles require a higher speed, and you can also use the cruise control to keep the speed constant. This method works only in some car models, often those that use the indirect method to measure tire air pressure.

Remove and Re-Connect the Car Battery

Every car has an onboard computer that may face certain glitches from time to time. The best way to fix these glitches is to reset the computer, and this can be done by disconnecting and reconnecting the battery.

Open your car’s hood and look for the battery’s negative terminal. Remove the negative terminal to disconnect the battery, then press the vehicle’s horn to drain out any remaining power. Reconnect the positive terminal, and the TPMS warning light should go away.

Use a TPMS Reset Tool for Your Vehicle

There are a lot of different TPMS reset tools on the market. In some cases, you will have to reprogram the sensors if they have lost their information, and you need a TPMS reset tool for this job. With a TPMS reset tool, you can often reset the TPMS light with an easy click of a button. If you are interested in buying a tool like this, I recommend the Autel TS401 MaxiTPMS Activation Tool Link from Amazon. You can also reset the TPMS light with a diagnostic scanner if you have a good OBD2 scanner. Always make sure the tools are compatible with your vehicle before making a purchase.

Damaged Sensors

If the above-mentioned techniques do not work, it may mean that the sensors may have been damaged and will have to be replaced. The sensors can get damaged due to various reasons; for example, tire replacement, brake repairing, oil change, filter change, or even during normal tire service.

The sensors do also have batteries inside of them, which will drail out after a couple of years.

You can also try out these specific methods depending on your car make and model.

Where is the TPMS Reset Button Located?

The TPMS reset button is often located under the steering wheel or integrated with the car’s information display system. This heavily differs depending on which car model you have though.

Down below, you will find some more vehicle-specific information about where the button is located.

TPMS Reset Chevrolet Models

Resetting TPMS on Chevrolet models can be performed at home as well, but it requires a J-46079 Tire Pressure Monitor Tester, which can be bought from eBay.

Put the key in the ignition and turn to the “ON” position, but don’t start the vehicle.
Using the driver instrument cluster, click the “Vehicle Information” button and navigate to “Relearn Tire Position”.
Click “Set/Reset” and a message saying “Tire Learning Active” will pop up.
If you own an old model without an instrument cluster, press the odometer reset button until “Tire Learning Active” message is displayed.
Connect the J-46079 Tire Pressure Monitor Tester to the left front tire and press the active button. Wait for 10 seconds until a horn chirp sound is heard. Repeat the process for the remaining tires.
Once all tires are done, turn the key to the “OFF” position.
Re-inflate the tires according to the recommended PSI.

TPMS Reset Volkswagen Models

Resetting TPMS on a Volkswagen differs from model to model. The reset button can be found inside the glove box or near the gear shift for old models. Once the button is found, press it for a couple of seconds until a beep is heard, then release.

For newer models, the TPMS can be re-calibrated easily through the infotainment system.

TPMS Reset Mini Models

The TPMS on Mini models can be re-calibrated easily through the button as well. For old models (2002 to 2006), the reset button can be found in the emergency brake handle’s front cabin.

Turn on the ignition – but don’t start the car – and press the reset button until the yellow indicator on the dashboard starts blinking. The TPS will be automatically calibrated on your next drive.

On the newer models (2007 and onwards), start the car and navigate to “Set/Info” on the instrument cluster. Scroll down until the tire monitor symbol is displayed, click on reset, and re-calibrate the TPMS system.

TPMS Reset Toyota Models

Toyota cars normally have a reset button under the steering wheel. The reset button can be hard to find, and you can find it in the lowest area in front of your pedals. Just press the reset button for 5 seconds while the ignition is on, and the TPMS should be reset.

Turn the ignition ON
Press the reset button for 5 seconds
Turn off the ignition
Start your car and check if the light is gone

Post-Reset Tips

Once the TPMS system resets and the warning light goes away, you can follow a few maintenance tips to avoid the problem in the future.

If you replace the valve-system core, choose a stainless steel core instead of a brass core.
Never leave the tire without a cap screwed to the valve stem.
Do not use aerosol flat fixer as it damages the sensor capability to measure changes.
Take your car to an authorized dealership to have your vehicle and tires inspected.

Can I Remove the TPMS Function instead?

It is possible, but you should remember that getting rid of the TPMS is not the right solution. According to the law proposed by “The National Highway Traffic Safety Administration (NHTSA),” all cars newer than 2008 are required to be equipped with a TPMS. This law was introduced to minimize the number of road accidents due to overinflated or underinflated tires.

When should I reset my TPMS?

The TPMS, or tire pressure monitoring system, should be reset when you change your tires. This is because most TPMS systems calculate your current tire pressure based on the size and weight of your original tires. When you switch to a different set of tires, the TPMS will not give an accurate reading.

Do you have to reprogram TPMS sensors when changing tires?

It depends on the car model. In some cars, you need to reprogram TPMS sensors when changing tires because the pressure information the sensors transmit will be incorrect if they are not calibrated to the new tires. In other car models, simply resetting the TPMS with the reset button may be sufficient.

Do TPMS sensors reset themselves?

Some TPMS sensors do reset themselves, but many do not. It depends on the make and model of the sensor. Some sensors have a “learn mode” that needs to be activated before the sensor will start transmitting data again. Others will continue to transmit data even if they are not reset. If you’re not sure how to reset your TPMS sensor, consult the owner’s manual or contact the manufacturer for assistance.

Can I drive with the TPMS light on?

While you can drive with a TPMS light on, it is not recommended as you will lose the ability to monitor tire pressure without doing so manually. It’s important to take care of this as soon as possible, as driving with an underinflated tire can lead to decreased fuel economy and increased wear and tear. If the TPMS light comes on while you’re driving, pull over at the next safe opportunity and check your tires’ air pressure levels. You can typically find the recommended levels in your car’s owner’s manual.

To reset a TPMS system, you must either press the TPMS reset button or use a TPMS reset tool after inflating the tires and making sure the tire pressure is correct. In some car models, the TPMS system will reset itself after you inflate the tires and drive for a while above 50 mph.

If your TPMS system has been reset according to the correct procedure for your car model and the TPMS light is still on, you may still have a problem with incorrect tire pressure in one or more of your tires.

Try checking the air pressure in each tire with another more accurate gauge (don’t trust gas station gauges) and inflate them up to the recommended PSI rating. If the light comes back on after driving for a while, there may be a faulty TPMS sensor in one of the tires.
