What Causes the Tire Pressure Warning on a Civic on the Highway?

[Katelyn]

The sudden display of a "Check Tire Pressure" message in a Civic is due to abnormal tire pressure triggering the tire pressure monitoring system (TPMS) alarm. After addressing the tire pressure issue, the warning will automatically disappear after driving for a while. If it persists, press the ENTER button on the right side of the steering wheel to enter the settings interface, then click the CANCEL button to manually clear the warning. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct TPMS uses pressure sensors installed in each tire to directly measure tire pressure. Wireless transmitters send pressure data from inside the tire to a central receiver module, which then displays the pressure for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When a tire's pressure drops, the vehicle's weight causes that tire's rolling radius to decrease, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect monitoring. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and addresses the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
