Tire pressure sensors help keep you safe on the road. They alert you when your tires have low air pressure. But sometimes, the light stays on even after filling the tires. That can be frustrating.

This guide explains how to reset the tire pressure sensor for most cars. With simple tools and a little time, the sensor light will turn off and your dashboard will look normal again.
What Does a Tire Pressure Sensor Do?
A tire pressure sensor watches the air pressure in your tires. If the pressure drops too low, the sensor tells your car’s system to turn on the warning light.

Resetting helps the system read the pressure correctly again.
How to Reset Tire Pressure Sensor Step-by-Step
Step 1: Check Tire Pressure First
Before trying anything else, use a tire gauge. Make sure all four tires have the correct air pressure. You’ll find the correct number on a sticker inside the driver’s door or in your manual. Most cars need 30–35 PSI.
Step 2: Turn the Car to “On”
Put your key in the ignition and turn it to the “On” position. Do not start the engine yet. The dash lights should come on.
Step 3: Press and Hold the TPMS Reset Button
Find the reset button under the steering wheel. It may be labeled “TPMS” or have the tire pressure icon. Press and hold it until the light on the dashboard blinks three times. Release the button.
Can’t find the button? Some cars hide it inside the glove box or near the gas pedal. Check your owner’s manual.
Step 4: Start the Car
Turn the key fully and start the engine. Wait a few minutes. The warning light should turn off.
What If Your Car Has No TPMS Button?
Some cars reset differently. Try these methods if there’s no reset button.
Method 1: Drive at a Steady Speed
Drive at 50 km/h (about 30 mph) for 10–15 minutes. The sensor may reset itself as the tires rotate.
