TPMS Light

Why Your TPMS Light Stays On (Even After Inflating Your Tires)

Your TPMS light turned on. You checked the pressure and filled your tires. But the warning light won’t go away. Why?

1. You Didn’t Drive Long Enough After Inflation

TPMS sensors need motion to update. Drive at least 10–15 minutes at highway speeds to reset the system automatically.

2. Your Spare Tire Has a Sensor Too

Many vehicles have TPMS sensors in the spare tire. Check and inflate your spare, especially if it’s full-size.

3. One Tire Still Has Low Pressure

Use a quality tire gauge—not the gas station one. A small pressure difference can still trigger the warning light.

4. Temperature Drop Affected Tire Pressure

Cold weather lowers air pressure. A 10°F drop can reduce pressure by 1 PSI. Recheck pressure during the coldest part of the day.

5. You Didn’t Reset the TPMS System

Some vehicles require a manual TPMS reset. Check your owner’s manual for the reset button or menu option.

6. The TPMS Sensor Battery Is Dead

TPMS sensors have internal batteries. They last 5–10 years. If dead, the sensor must be replaced—not recharged or repaired. Our U-Pro Hybrid NFC programmable TPMS sensor with valves is a universal replacement that works with most vehicles.

7. Your Vehicle Has an Indirect TPMS System

Indirect TPMS doesn’t use sensors. It measures wheel speed through ABS. Resetting may require a dash menu or scan tool.

8. Sensor Was Damaged During Tire Service

If your light came on after a tire change, the sensor may be cracked, unprogrammed, or missing. Have a shop check it.

9. You Installed New Wheels Without Compatible Sensors

Aftermarket wheels may not have TPMS sensors installed. You’ll need to transfer or install new compatible ones for the system to work.

10. TPMS Relearn Procedure Was Skipped

After replacing a sensor, most systems need a relearn. Use a TPMS scan tool or follow your vehicle’s relearn instructions.

How to Clear the TPMS Light

  1. Check and inflate all four tires (plus spare if equipped).
  2. Drive for 10+ minutes at 50 mph.
  3. If the light stays on, reset TPMS using your vehicle’s method.
  4. If still unresolved, scan for TPMS fault codes or visit a trusted shop.

When to See a Professional

If you’ve tried everything and the TPMS light still won’t turn off, the issue is likely sensor-related. A professional can scan the system and pinpoint which sensor has failed.

Keep Your TPMS System Reliable

Use a digital pressure gauge regularly. And always ask your tire shop to verify sensor function after service.
