Utilize a reliable tire pressure gauge to ensure each tire is inflated to the specifications outlined in your owner's manual. If you discover any discrepancies, adjust the pressure by either adding air to underinflated tires or releasing air from those that are overinflated. Next, conduct a visual inspection of each tire for any signs of damage, such as punctures or bulges, which could contribute to pressure loss. After making the necessary adjustments, check if your vehicle requires a manual reset of the tire pressure monitoring system, as this step is crucial for the warning light to turn off. Additionally, remember to inspect the spare tire, as low pressure in this tire can also trigger the warning light. If the warning persists despite these efforts, it may indicate a more complex issue, such as a faulty sensor, at which point seeking assistance from a professional mechanic is advisable. By following this diagnostic approach, you can systematically address the tire pressure warning light issue and ensure your vehicle's safety and performance.

What could be causing the tire pressure warning light to remain on in a 2012 Mitsubishi i-MiEV?

Additionally, sensor calibration issues can lead to incorrect readings, which can be rectified by a professional. Electrical problems, such as damaged wiring or connections within the tire pressure monitoring system, can also cause the warning light to illuminate. Lastly, a low battery in the tire pressure sensor itself may need to be replaced to ensure proper operation. It is important to address these issues promptly to maintain the safety and performance of your vehicle.
