What Causes the Fault in Roewe's Tire Pressure Monitoring System?
2 Answers
Roewe's tire pressure monitoring system may detect a fault due to issues with the tires. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. Having a tire pressure monitoring system significantly enhances vehicle safety. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure while the vehicle is in motion, alerting the driver to leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data 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 the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): TPMS combines the advantages of both systems mentioned above. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
I've been repairing cars for over a decade and have encountered numerous Roewe tire pressure warning issues with various causes. The most common is a dead sensor battery—those things are tucked inside the tires and typically last 3-5 years before needing replacement. Another frequent issue is physical damage to sensors, whether from hard impacts like potholes or corrosion from muddy off-road conditions. Receiver malfunctions also occur; the small box near the driver's seat can fail, requiring diagnostic tools to identify and replace it. Sometimes the system needs relearning after tire rotations—if dashboard settings aren't reset, false alarms are guaranteed. Parking near high-voltage power lines can cause signal interference triggering constant warnings. In rare cases, check the fuse box for blown fuses related to the system. Never ignore these alerts—incorrect tire pressure compromises safety, so professional diagnosis is always the wisest approach.
