Next, conduct a thorough inspection of the tires for any visible damage, such as punctures, cuts, or bulges, and look for signs of uneven wear that may suggest an alignment problem. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system, as some vehicles allow for this after correcting the tire pressure. If the warning light remains illuminated, it may indicate a faulty tire pressure sensor, which would require a diagnostic tool to identify the malfunctioning sensor.
