Tire Pressure (TPMS) Light: what it means and what to do
Color: Amber/yellow
Urgency: Check soon. Flashing then steady usually means a sensor fault.
What it means
One or more tires is significantly below recommended pressure, or the TPMS system has a fault.
Is it safe to drive?
Generally yes at moderate speed to a gas station, but check tires first: a badly underinflated tire can fail.
Likely causes
- Low tire pressure (cold weather drops pressure)
- Slow leak or puncture
- Dead TPMS sensor battery
- Sensor damaged during tire service
Typical cost ranges
Rough general estimates for US shops (parts and labor). Your price depends on vehicle, region, and shop.
| Repair | Rough range |
|---|---|
| Air | $0–$2 |
| Tire plug/patch | $20–$50 |
| TPMS sensor | $50–$250 per wheel |
| TPMS relearn | $0–$75 |
What to tell the shop
Tell them the light pattern (solid vs. flashing first) and which tire was low. Recommended pressure is on the driver door jamb sticker, not the tire.
