Tire Pressure Monitoring System (TPMS) Warning Light Always On
The TPMS warning light is constantly illuminated on a 2019 Honda Accord, indicating that one or more tires have low pressure or the system has a fault. This can lead to reduced fuel efficiency, uneven tire wear, and potential safety risks if tire pressure is significantly low.

One or more tires have low air pressure due to a slow leak, temperature changes, or normal air loss.
