  • Use the TPMS reset button: Many vehicles have a dedicated button under the steering wheel or in the glove box to reset the system.
  • Drive to recalibrate: Some cars require a short drive at a specific speed (usually 50+ mph) to allow the sensors to sync and clear the light.
  • Scan tools work for advanced systems: If manual methods fail, an OBD2 scanner with TPMS functionality can reset the light and reprogram sensors.
  • Seasonal changes matter: Cold weather can drop tire pressure and trigger the light—check and adjust regularly in winter.
  • Don’t ignore the light: A persistent warning could signal a slow leak, damaged sensor, or other issue needing professional inspection.
  • Consult your owner’s manual: Every vehicle is different—your manual has the most accurate reset procedure for your specific model.

Why the Tire Pressure Light Comes On—And Why You Shouldn’t Ignore It

You’re driving along, enjoying your morning commute, when suddenly—a yellow or orange light flashes on your dashboard. It looks like a tire with an exclamation point inside. That’s the tire pressure monitoring system (TPMS) light, and it’s your car’s way of saying, “Hey, something’s not right with your tires.”

At first glance, it might seem like a minor annoyance. But ignoring it could lead to bigger problems. Low tire pressure reduces fuel efficiency, increases tire wear, and can even cause a blowout at high speeds. On the flip side, overinflated tires can make your ride harsher and reduce traction. The TPMS light is there to protect you, your passengers, and your vehicle.

So, how do you reset the tire pressure light? The good news is that in most cases, it’s a straightforward process. But the exact steps depend on your car’s make, model, and year. Some vehicles let you reset it with a simple button press. Others require a short drive or even a special tool. The key is to understand why the light came on in the first place—and to fix the root cause before resetting it.

Understanding Your Tire Pressure Monitoring System (TPMS)

Before you can reset the tire pressure light, it helps to know how the system works. There are two main types of TPMS: direct and indirect.

Direct TPMS

This system uses sensors mounted inside each tire (usually attached to the valve stem) to measure air pressure in real time. These sensors send data wirelessly to your car’s computer. If the pressure drops below the recommended level—typically 25% or more—the system triggers the warning light. Direct TPMS is more accurate and is now standard on most vehicles sold in the U.S. since 2008.

Indirect TPMS

This system doesn’t use physical pressure sensors. Instead, it relies on the wheel speed sensors that are part of the anti-lock braking system (ABS). When a tire is underinflated, it rotates faster than the others. The ABS detects this difference and triggers the TPMS light. While less precise, indirect systems are cheaper to maintain since there are no sensors in the tires.

Knowing which type your car uses can help you troubleshoot. For example, if you’ve recently rotated your tires or replaced a sensor, a direct system may need to be recalibrated. An indirect system might just need a drive to “relearn” the normal rotation speeds.

Step-by-Step Guide: How Do You Reset the Tire Pressure Light

Now that you understand the basics, let’s get into the nitty-gritty. Here’s a general step-by-step process that works for most vehicles. But remember—always check your owner’s manual for model-specific instructions.

Step 1: Check and Adjust Tire Pressure

Before resetting the light, make sure all four tires (and the spare, if equipped) are properly inflated. Use a reliable tire pressure gauge to check each tire. The correct PSI is usually listed on a sticker inside the driver’s door jamb or in the owner’s manual. Don’t rely on the number printed on the tire sidewall—that’s the maximum pressure, not the recommended one.

For example, if your car calls for 32 PSI and one tire reads 28, inflate it to the correct level. Cold weather can cause pressure to drop by about 1 PSI for every 10°F drop in temperature. So if it’s been chilly overnight, your tires might be low even if they were fine yesterday.

Step 2: Turn the Ignition On (But Don’t Start the Engine)

Insert your key and turn it to the “ON” position. This powers up the car’s electronics without starting the engine. If you have a push-button start, press the button once (without pressing the brake) to enter accessory mode.

This step is crucial because the TPMS system needs power to communicate with the sensors. You’ll usually see the TPMS light flash or stay on during this phase—that’s normal.

Step 3: Locate the TPMS Reset Button

In many vehicles, there’s a small button labeled “TPMS,” “SET,” or “RESET” located under the steering column, near the fuse box, or inside the glove compartment. It’s often black or yellow and may require a paperclip or pen to press.

For example, on a Honda Accord, the button is usually under the dashboard on the left side. On a Ford F-150, it might be near the OBD2 port. If you can’t find it, check your manual—or search online for your specific model.

Step 4: Press and Hold the Reset Button

Once you’ve found the button, press and hold it for 3 to 5 seconds. You should see the TPMS light blink three times, then stay on. This indicates the system is in reset mode.

Some cars require you to press the button multiple times or follow a specific sequence. For instance, on certain Toyotas, you press the button until the light blinks, then turn the ignition off and on again.

Step 5: Drive the Vehicle to Recalibrate

After pressing the reset button, start the engine and drive the car at a steady speed—usually between 30 and 60 mph—for about 10 to 20 minutes. This allows the sensors to communicate with the computer and confirm that all tires are properly inflated.

During this drive, avoid sudden braking or sharp turns. The system needs consistent data to reset properly. Once the recalibration is complete, the TPMS light should turn off.

Step 6: Verify the Light Is Off

After your drive, park the car and check the dashboard. If the light is off, congratulations—you’ve successfully reset it! If it’s still on, repeat the process or consider using a scan tool.

Vehicle-Specific Reset Procedures

Not all cars follow the same reset pattern. Here are a few common examples to help you out.

Resetting the TPMS Light on a Honda

On most Honda models (like the Civic, Accord, or CR-V), the process is simple:

  • Turn the ignition to “ON.”
  • Press and hold the TPMS button (usually under the steering wheel) until the light blinks twice.
  • Drive the car at 30+ mph for at least 10 minutes.

The light should turn off once the system confirms proper pressure.

Resetting the TPMS Light on a Toyota

Toyotas often require a slightly different approach:

  • Inflate all tires to the recommended PSI.
  • Turn the ignition to “ON.”
  • Press and hold the TPMS reset button until the light blinks three times.
  • Turn the ignition off, then back on.
  • Drive at 19+ mph for 10–15 minutes.

Some newer Toyotas use a “SET” button on the instrument panel instead of a physical button.

Resetting the TPMS Light on a Ford

Ford vehicles (like the F-150 or Escape) typically use this method:

  • Turn the ignition to “ON.”
  • Press the brake pedal three times.
  • Press the hazard light button three times.
  • Turn the ignition off.
  • Start the engine and drive at 30+ mph for 10 minutes.

This sequence tells the system to relearn the sensor IDs.

Resetting the TPMS Light on a Chevrolet

Chevy models (such as the Silverado or Equinox) often require a scan tool for a full reset. However, you can try this manual method first:

  • Turn the ignition to “ON.”
  • Press and hold the lock and unlock buttons on the key fob simultaneously for 5 seconds.
  • The horn should chirp, indicating the system is in reset mode.
  • Drive the vehicle for 10–15 minutes at 30+ mph.

If the light persists, a professional scan tool may be needed.

When Manual Reset Doesn’t Work: Using a TPMS Scan Tool

Sometimes, the manual reset method just doesn’t cut it. This is especially true if you’ve recently replaced a tire sensor, rotated your tires, or installed new wheels. In these cases, a TPMS scan tool can save the day.

What Is a TPMS Scan Tool?

A TPMS scan tool is a handheld device that communicates directly with your car’s tire pressure sensors. It can read sensor IDs, check battery life, and reprogram the system after tire service. Some advanced models even let you reset the light without driving.

Popular options include the Autel MaxiTPMS TS508, the Foxwell NT510, and the cheaper but effective BlueDriver TPMS tool. Many auto parts stores (like AutoZone or O’Reilly) also offer free TPMS resets if you purchase sensors from them.

How to Use a Scan Tool to Reset the Light

Here’s a general process:

  • Turn the ignition to “ON.”
  • Connect the scan tool to the OBD2 port (usually under the dashboard).
  • Follow the on-screen prompts to access the TPMS menu.
  • Select “Reset” or “Relearn” and follow the instructions.
  • The tool will communicate with each sensor and confirm the reset.

After the process, drive the car briefly to ensure the light stays off.

When to See a Professional

If you’ve tried everything and the light won’t reset, it’s time to visit a mechanic or tire shop. Possible issues include:

  • A dead or damaged TPMS sensor.
  • A faulty TPMS control module.
  • A wiring problem in the system.
  • A tire with a slow leak or puncture.

A professional can diagnose the issue and replace parts if needed. Don’t ignore a persistent light—it could mean a serious safety risk.

Common Mistakes to Avoid When Resetting the TPMS Light

Even experienced drivers can make mistakes when resetting the tire pressure light. Here are a few common pitfalls to watch out for.

Resetting Without Fixing the Problem

The biggest mistake? Resetting the light while your tires are still underinflated. This doesn’t solve the issue—it just hides it. Always check and adjust tire pressure first. Otherwise, the light will come back on, and you’ll be back to square one.

Using the Wrong PSI

Don’t guess the correct tire pressure. Always refer to the sticker on your door jamb or the owner’s manual. Using the sidewall number can lead to overinflation, which reduces traction and increases wear.

Ignoring the Spare Tire

Some TPMS systems monitor the spare tire. If you’ve recently rotated tires or replaced a flat, make sure the spare is also properly inflated. A low spare can trigger the light on certain vehicles.

Not Driving Long Enough

After a reset, many systems require a minimum drive time or speed to complete the recalibration. If you reset the light and immediately park the car, it may not finish the process. Always follow the recommended drive procedure.

Assuming All Cars Work the Same

Just because your friend reset their Toyota with a button press doesn’t mean your Ford will work the same way. Always consult your owner’s manual or look up your specific model online.

Tips for Preventing TPMS Light Issues

The best way to deal with the tire pressure light is to avoid it altogether. Here are some proactive tips to keep your TPMS system happy.

Check Tire Pressure Monthly

Make it a habit to check your tire pressure at least once a month. Use a quality gauge and do it when the tires are cold (before driving). This helps you catch slow leaks or seasonal drops early.

Rotate Your Tires Regularly

Tire rotation (every 5,000 to 7,000 miles) ensures even wear and can help prevent pressure imbalances. Just remember that some TPMS systems need to be recalibrated after rotation.

Replace Sensors When Needed

TPMS sensors have batteries that last 5 to 10 years. If a sensor dies, the light may stay on or flash. Most tire shops can test sensor batteries and replace them if necessary.

Be Mindful of Seasonal Changes

Cold weather is a major cause of low tire pressure. In winter, check your tires more frequently. Consider using nitrogen inflation, which is less affected by temperature changes (though regular air works fine too).

Keep Your Owner’s Manual Handy

Your manual is your best friend when it comes to TPMS. It has the exact reset procedure, recommended PSI, and troubleshooting tips for your vehicle. Keep it in the glove box for quick reference.

Final Thoughts: Stay Safe, Stay Informed

Resetting the tire pressure light might seem like a small task, but it plays a big role in your safety and vehicle performance. By understanding how your TPMS works and following the right steps, you can keep your tires in top shape and avoid unnecessary stress.

Remember, the light is there for a reason. Don’t just reset it and forget about it—take the time to check your tires, adjust the pressure, and ensure everything is working as it should. Whether you’re using a simple button press or a high-tech scan tool, the goal is the same: a safer, smoother, and more efficient ride.

So the next time that little tire light pops up, don’t panic. You’ve got this. Just follow the steps, stay calm, and keep rolling.
