Tire Pressure Warning Light
The Tire Pressure Monitoring System (TPMS) indicates that one or more tires may have incorrect pressure or that a TPMS sensor/system fault has been detected.
Check all four tires and the spare if monitored. Inflate them to the vehicle manufacturer's specified cold pressure and inspect for damage.
The TPMS warning light helps identify unsafe tire pressure conditions. Pressure changes can occur with temperature, but a persistent warning may indicate a puncture, leak, sensor fault, or relearn issue.
⚠️ Drive With Caution
If a tire is visibly damaged or severely underinflated, stop driving. Otherwise, correct the tire pressures before extended driving.
$0-$300+ depending on whether the cause is pressure, a puncture, valve, or sensor
Repair costs vary depending on the exact diagnostic trouble code, vehicle make and model, labor rates, and which component has failed. Always diagnose the problem before replacing any parts.
Check tire pressure first when the TPMS light appears. Correct pressure protects handling, braking, tire life, and fuel economy.
What does the TPMS light mean?
At least one tire has fallen roughly 25% below its placard pressure, or the monitoring system itself has a fault. A steady lamp points at pressure; a lamp that flashes for about a minute at startup then stays on points at the system.
Can I drive with the TPMS light on?
Drive gently to the nearest air pump and check all four tires. If one is visibly flat or the sidewall is damaged, do not drive on it: use the spare or call for assistance.
How is a TPMS warning diagnosed?
Measure every tire cold with a gauge rather than trusting the dashboard readout, and include the spare if your vehicle monitors it. Inspect the treads and sidewalls for punctures, soap-test the valves for slow leaks, and if pressures are correct, read the sensor IDs with a TPMS tool and run the vehicle relearn procedure.
How much does it cost to fix a TPMS light?
Usually nothing if the tires just need air. A puncture repair is around $25-$45, and a replacement TPMS sensor including the relearn is typically $60-$150 per wheel.
