Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could lead to air loss and trigger the warning light. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system (TPMS) as it may require recalibration after adjustments. If the light persists, the issue may lie with a malfunctioning tire pressure sensor, which may necessitate the use of a professional diagnostic tool for accurate identification. Should these steps not resolve the issue, it is advisable to consult a qualified mechanic for a comprehensive inspection of the TPMS system.
