It's crucial to ensure that the pressure aligns with the manufacturer's specifications, which can typically be found in the owner's manual or on a sticker located inside the driver's door jamb. Next, inspect each tire for any visible damage, such as punctures, cuts, or bulges, and look for signs of uneven wear that may suggest alignment problems or improper inflation. If the tire pressure is correct and the tires appear to be in good condition, proceed to reset the tire pressure monitoring system (TPMS) as outlined in your owner's manual, as this can often resolve the warning light issue. However, if the light remains illuminated, it may indicate a malfunctioning TPMS sensor, which is located inside the tire. In this case, consulting a professional mechanic is advisable for a thorough diagnosis and potential replacement of faulty sensors.

Additionally, sensor calibration issues might prevent accurate readings, necessitating a recalibration process that can often be done following the vehicle's manual. Electrical faults within the tire pressure monitoring system can also cause the warning light to remain illuminated, which may require a diagnostic check to identify the specific issue. Lastly, performing a system reset could resolve the warning light if all other factors appear normal.

If you find any tires that are low, inflate them using a dependable air compressor. Next, inspect each tire for visible damage such as punctures or bulges, as these can compromise safety and performance. If any damage is detected, it may be necessary to repair or replace the affected tire. After ensuring that the tire pressures are correct and the tires are in good condition, reset the tire pressure monitoring system according to the vehicle's manual. If the warning light persists despite these efforts, it is advisable to consult a qualified mechanic, as there may be a deeper issue with the monitoring system that requires professional attention.
