Tire Pressure Light: What It Means and What To Do

Yellow Solid or blinking Caution General

Quick answer: A tire pressure light usually means one or more tires are underinflated, but a blinking TPMS light can indicate a sensor or system problem.

What this light usually means

A tire pressure light usually means one or more tires are underinflated, but a blinking TPMS light can indicate a sensor or system problem. The exact meaning can depend on the device model, the label beside the light, and whether the light is solid, blinking, flashing, pulsing, or alternating with another color.

Common causes

  • One or more tires are low
  • Temperature drop changed tire pressure
  • Slow leak or puncture
  • TPMS sensor battery issue
  • TPMS system fault

What to check first

  1. Check tire pressure with a gauge.
  2. Inflate tires to the pressure listed on the driver door placard.
  3. Inspect for nails, damage, or visible low tires.
  4. Drive briefly after inflating if the manual says the system needs time.
  5. Have the tire checked if pressure drops again.

Important warning

Do not rely only on appearance. A tire can be dangerously low before it looks flat.

When it may be normal

This light may be normal if the device recently powered on, is pairing, is charging, is updating, is connecting, or is completing a setup step. If the light changes after a few minutes and the device works normally, it may not require further action.

When to contact support

Contact the manufacturer or a qualified professional if the light stays on after basic checks, appears with warning sounds, appears with heat or burning smells, affects a safety device, or comes back repeatedly after restarting.
