How to Resolve the Tire Pressure Monitoring Light?
1 Answers
Indirect tire pressure monitoring uses wheel speed sensors to compare the rotational speeds of the tires to determine if there is abnormal tire pressure. If a monitoring fault is detected, it is likely due to a malfunctioning wheel speed sensor or poor internal contact. Four methods to resolve the tire pressure monitoring light: 1. The tire pressure monitoring light may come on due to a punctured tire. This situation usually involves a very slow leak, making it difficult to immediately identify which tire is affected. In this case, use a tire pressure gauge to measure the pressure (front: 2.3 bar, rear: 2.5 bar). If the pressure is insufficient, observe the tire pressure warning light. If it lights up again after a few days, it may be necessary to remove the tire for inspection. 2. Sometimes, the tire pressure monitoring light comes on due to excessive tire pressure. According to international standards, the recommended inflation pressure for passenger car tires is: standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. 3. The tire pressure monitoring light may come on due to prolonged driving with low tire pressure. This usually occurs when a tire's pressure is too low, causing the tire temperature to rise during high-speed operation, which in turn increases the tire pressure. In such cases, stop and rest or replace the tire with a spare immediately. 4. The tire pressure monitoring light may come on due to long-term neglect of tire inflation, resulting in low tire pressure. Regular checks should be performed to ensure the tire pressure monitor is functioning properly. If the tire pressure monitor fails to alert you promptly when an issue arises, it may indicate a problem with the monitor itself.
