Abnormal Tire Pressure Warning Symbol in Cars?
1 Answers
It is a partially enclosed exclamation mark. Different tire pressure monitoring systems may display different warnings - those showing specific pressure values will directly indicate abnormal readings, while non-numeric systems will display an exclamation mark symbol. Tire Pressure Monitoring Light Illumination: The tire pressure monitoring indicator is a yellow symbol featuring an irregular circle without top closure, with four small spikes at the bottom and an exclamation mark inside. When illuminated, it indicates abnormal tire pressure. There are generally three causes for abnormal tire pressure: Abnormal Tire Inflation Pressure: The system typically triggers warnings when pressure falls below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are required. Unreset Tire Pressure Monitoring System: After tire inflation, if the system isn't properly reset, it continues to display previously recorded data, causing the warning light to activate. Simply performing a tire pressure reset will resolve this. Damaged Tire Pressure Sensor: The tire pressure sensor, installed internally within the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), it triggers the warning light. Sensor damage requires complete replacement with new components.
