Next, visually inspect the tires for any signs of damage, such as punctures, cuts, or bulges, and look for uneven wear patterns that may suggest alignment problems. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system, as some vehicles allow for a manual reset; refer to your owner's manual for specific instructions. If the warning light remains illuminated, it may indicate a malfunctioning tire pressure sensor, which would require diagnostic tools to identify the faulty component.

Additionally, the sensors could require recalibration to ensure they provide accurate readings, a process that is typically outlined in the vehicle's manual. Electrical faults within the tire pressure monitoring system (TPMS) can also cause the warning light to remain illuminated, and in such cases, a professional diagnostic check may be necessary to identify the root cause.
