What Does TPMS Warning Light — Low Tire Pressure Mean?
Reviewed by automotive technicians · Last updated July 11, 2026
Quick Answer
TPMS Warning Light — Low Tire Pressure = The Tire Pressure Monitoring System has detected that one or more tires are below the recommended cold inflation pressure (typically 35 PSI on Ford Explorer). A solid TPMS light means low tire pressure. A flashing TPMS light (60-90 seconds on startup then solid) means a system fault — a dead sensor or communication loss.

What to Do Right Now
Check all four tire pressures with a gauge as soon as possible. The recommended pressure is on the driver's door jamb sticker — do NOT use the max PSI on the tire sidewall. Inflate any tire below 30 PSI immediately — driving on underinflated tires causes premature wear, reduced fuel economy, and risk of a blowout. If all tires are at correct pressure but the light stays on, the system may need a TPMS relearn (hold the reset button under the steering wheel with key ON/engine OFF).
