How to Reset the Tire Pressure Light

If you’re seeing a flashing tire pressure light on your dashboard, it’s likely your vehicle’s Tire Pressure Monitoring System (TPMS) is detecting an issue. The TPMS light on typically indicates that one or more tires are underinflated, but after you’ve resolved the issue, the light might still stay on. Knowing how to reset the tire pressure light can save you a trip to the service center near New Haven and help ensure your vehicle is operating safely.

Why is my TPMS Light on?

Before diving into how to reset the tire pressure light, it’s essential to understand why it might be on in the first place. Common reasons include:

• Low tire pressure: Temperature changes can cause the air in your tires to expand or contract, which can trigger the TPMS.
• A puncture or slow leak: If one of your tires is losing air faster than the others, it may trigger the TPMS light on.
• Faulty sensor: Sometimes the TPMS sensor can malfunction, causing a false warning.

How to Reset the Tire Pressure Light

Once you’ve inflated your tires to the recommended levels, you may need to manually reset the system. Here’s how to reset the tire pressure light in most vehicles: 

1. Check tire pressure. Make sure all tires, including the spare, are inflated to the correct PSI. You can find this information on a sticker inside the driver’s door or in the owner’s manual.
2. Turn the ignition on. Without starting the car, turn the key to the “on” position (or press the start button twice without pressing the brake).
3. Press and hold the TPMS reset button. This button is usually located under the steering wheel. Hold it down until the flashing tire pressure light blinks three times, then release it.
4. After resetting the light, drive at least 20 minutes to allow the system to recalibrate. The light should turn off on its own once the system has verified the tire pressure is correct.

Additional Steps if the TPMS Light Stays On

If your TPMS light is still on after trying the above steps, there could be other issues to address:

• Check for a sensor malfunction. A faulty TPMS sensor could cause the light to stay on even if your tire pressure is correct.
• Reset using the vehicle’s menu. In some vehicles, you can reset the TPMS through the infotainment system or dashboard menu. Consult your owner’s manual for instructions.
