Ensure that the readings align with the recommended levels found in your vehicle's manual, as incorrect pressure is a common trigger for the warning light. Next, inspect each tire for visible damage, such as punctures, cuts, or bulges, which could indicate a loss of pressure. Don’t overlook the valve stems; check them for any signs of damage or leaks, as faulty valve stems can also lead to pressure loss. If everything appears normal, attempt to reset the tire pressure monitoring system following the instructions in your owner's manual, as this can sometimes resolve minor glitches.

If the pressure is adequate, the problem may lie with a faulty tire pressure sensor, which could require replacement or recalibration. Additionally, some sensors are powered by batteries that can deplete over time, necessitating a battery replacement. It's also important to inspect the wiring and connections associated with the tire pressure monitoring system, as damaged or loose connections can trigger the warning light. Lastly, if all else fails, recalibrating the system according to the manufacturer's guidelines may resolve the issue.
