How to Reset a Tire Pressure Monitoring Sensor (TPMS) for All Vehicle Types?

What Is a Tire Pressure Sensor?

A tire pressure sensor monitors the air pressure inside your tyres and sends real-time data to the vehicle's onboard computer. When pressure drops too low or becomes uneven, the system triggers a dashboard warning light

There are two main types of TPMS:

• Direct TPMS - Uses physical sensors inside each tyre.
• Indirect TPMS - Uses wheel speed data from the ABS to estimate pressure.

Both systems may require recalibration after maintenance.

When Should You Reset the TPMS?

You should reset your tire pressure sensor if:

• The TPMS warning light stays on after inflating tyres
• Tyres have been rotated or replaced
• A tyre pressure sensor has been changed
• Seasonal tyre changes were performed
• The warning light flashes or behaves inconsistently

Step 1: Set Correct Tyre Pressure

Before resetting the system, ensure tyre pressure is correct.

• Park the vehicle on a flat surface.
• Check tyre pressure when tyres are cold.
• Inflate or deflate each tyre to the manufacturer-recommended PSI.
• Don't forget to check the spare tyre if applicable.

Resetting the TPMS without proper tyre pressure will lead to inaccurate readings.

Method 1: Reset Using the TPMS Reset Button

Many vehicles include a TPMS reset button.

Steps:

• Turn the ignition to the ON position without starting the engine.
• Locate the TPMS reset button (usually under the steering wheel, glove box, or dashboard).
• Press and hold the button until the TPMS light blinks.
• Release the button and start the vehicle.
• Drive for 10-15 minutes to allow the system to recalibrate.

Method 2: Reset Through Vehicle Settings Menu

Newer vehicles often use digital menus instead of physical buttons.

Steps:

• Turn the ignition on.
• Access the vehicle settings via the dashboard or infotainment screen.
• Navigate to "Vehicle," "Tyre Settings," or "TPMS Calibration.”
• Select "Reset" or "Relearn.”
• Drive the vehicle to complete the process.

Method 3: Drive to Trigger Automatic Recalibration

Some TPMS systems recalibrate automatically.

Steps:

• Ensure all tyres are properly inflated.
• Drive at a steady speed between 40-80 km/h for about 10-20 minutes.
• The system will relearn pressure values and turn off the warning light.

Method 4: Battery Disconnect Reset

If standard methods fail, a battery reset may help.

Steps:

• Turn off the vehicle.
• Disconnect the positive battery terminal.
• Wait 5-10 minutes.
• Reconnect the battery.
• Drive the vehicle to allow sensor relearning.

Note: This may reset other vehicle settings like the clock or radio.

When Professional Reset Is Required

In some cases, resetting TPMS requires specialized diagnostic tools, especially when:

• Sensors are replaced
• Sensor batteries are dead
• The TPMS light flashes continuously
• The system fails to relearn after reset attempts

A professional technician can perform sensor relearning using an OBD tool.

Common TPMS Reset Mistakes to Avoid

• Resetting without adjusting tyre pressure
• Ignoring a flashing TPMS warning light
• Forgetting to drive after a reset
• Assuming the system is faulty without checking sensors

Benefits of Proper TPMS Maintenance

• Improved driving safety
• Better fuel efficiency
• Longer tyre lifespan
• Accurate dashboard warnings
• Reduced risk of blowouts

A proper heavy vehicle inspection NSW isn’t just a requirement it’s the key to safer roads, fewer fines, and smoother fleet operations.

Conclusion

Resetting a tire pressure sensor is usually a simple task, but it must be done correctly. Always start by checking tyre pressure, then follow the reset method suitable for your vehicle. If the warning light persists, professional inspection may be required. Regular tyre maintenance ensures your TPMS functions accurately, keeping your vehicle safe, efficient, and road-ready.
