TPMS Light On After Filling Tires – 2023


Having the TPMS (Tire Pressure Monitoring System) light illuminate on your dashboard after filling your tires can be a frustrating experience. Understanding why this happens and how to address it can help ensure your vehicle’s safety and proper tire maintenance.

Why Does the TPMS Light Come On?

The TPMS light typically comes on when there is a significant difference in tire pressure between the recommended level and the current pressure detected by the sensors in your tires. There are various reasons why this difference may occur, such as temperature changes or a leak in the tire.

Temperature Changes

Temperature fluctuations can cause changes in tire pressure. When the temperature drops, the air inside the tires contracts, leading to lower pressure readings. Similarly, when the temperature rises, the air expands, resulting in higher pressure. Such variations can trigger the TPMS light.

Tire Leaks

If your TPMS light comes on after filling your tires, it could indicate a leak. Even a small puncture or damage to the tire can cause air to slowly escape, leading to a drop in pressure. It’s essential to inspect your tires for any visible signs of damage or seek professional assistance to identify and fix leaks.

What to Do When the TPMS Light Comes On?

When the TPMS light illuminates after filling your tires, follow these steps:

1. Check Tire Pressure

Use a reliable tire pressure gauge to check the pressure in all four tires, including the spare if applicable. Compare the readings to the recommended pressure levels specified by the vehicle manufacturer, usually found on a sticker inside the driver’s side door frame or in the owner’s manual.

2. Inflate or Deflate Accordingly

If the tire pressure is too low, add air until it reaches the recommended level. Conversely, if the pressure is too high, release some air to bring it down to the appropriate level. Remember to check the pressure frequently to maintain optimal tire performance.

3. Inspect for Leaks

Closely examine each tire for any visible signs of punctures, cuts, or embedded objects. If you suspect a leak, it’s advisable to visit a professional tire service center for a thorough inspection and repair.

4. Reset the TPMS

After addressing any tire pressure issues, you may need to reset the TPMS light. The process varies depending on the vehicle make and model, so refer to the owner’s manual for specific instructions. In some cases, simply driving the vehicle for a few miles may reset the system automatically.


Experiencing the TPMS light coming on after filling your tires can be a sign of temperature changes or potential leaks. By checking tire pressure regularly, addressing any issues promptly, and resetting the TPMS as needed, you can maintain the safety and performance of your vehicle’s tires.
