  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.

Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could indicate a loss of air. Don’t forget to examine the valve stems as well; any cracks or leaks here can also lead to pressure drops. To confirm your findings, use a reliable tire pressure gauge to measure the actual pressure in each tire, ensuring accuracy in your assessment.

Refer to your vehicle's manual for specific instructions on how to perform this reset.
