Next, conduct a visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, which could indicate a loss of pressure. Additionally, check for leaks by examining the tires and valve stems closely; a simple mixture of soap and water can help reveal any leaks through the formation of bubbles. Don’t overlook the spare tire, as it can also trigger the warning light if its pressure is low. If all tires are in good condition and properly inflated, you may need to reset the tire pressure monitoring system, which can typically be done via the vehicle's onboard computer or by following the reset instructions in the owner's manual.

If tire pressure is not the issue, a faulty tire pressure sensor could be the culprit, potentially requiring replacement to restore proper function. Additionally, sensor calibration may be necessary if the sensors are not accurately reading the tire pressure. Electrical problems, such as damaged wiring or poor connections within the tire pressure monitoring system, can also trigger the warning light, making it important to inspect these components.
