TPMS Checker
The tire pressure monitoring system (TPMS) light behaves differently depending on the problem. Select your symptom to get the likely cause and the right next step.
How it works
A steady TPMS light usually means low pressure; a blinking light that stays on means a system fault, typically a dead or missing sensor. Indirect systems (using wheel-speed sensors) can also trigger after tire changes until the system relearns.
Frequently asked questions
Can I drive with the TPMS light on?
Check and inflate the tires first. A steady light with correct pressures usually clears after a short drive. A blinking light (system fault) does not stop the car but should be diagnosed soon.
Do I need to reset the TPMS?
Many cars need a reset (button in the glovebox or a menu option) after inflating or changing wheels. Some indirect systems re-learn automatically after driving.
