  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.

Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the recommended PSI found in your owner's manual or on the sticker located inside the driver's side door jamb. Next, conduct a thorough visual inspection of each tire for any signs of damage, such as punctures or bulges, and look for any foreign objects that may be lodged in the tread. If you find that any tires are underinflated or overinflated, adjust the pressure accordingly, using the gauge to achieve the correct PSI. After making these adjustments, consult your owner's manual to determine if a manual reset of the tire pressure monitoring system (TPMS) is necessary. If the warning light remains illuminated, it may indicate a malfunctioning tire pressure sensor, which could require professional diagnosis and potential replacement. If you are unable to resolve the issue through these steps, it is advisable to seek assistance from a qualified mechanic who can provide a more in-depth inspection and repair.
