How to Solve the Tire Pressure Sensor Malfunction in the Everest?
1 Answers
Tire pressure sensor malfunctions can be caused by various reasons, and troubleshooting should be based on specific symptoms. First, the vehicle's tire pressure monitoring system needs to be inspected. When the system malfunctions, the tire pressure warning light will flash for about a minute, and it is advisable to visit a 4S shop for further diagnosis. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the air 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 other wheels. By comparing the rotational speed differences between tires, the system monitors the tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor air pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of both the above systems. It is equipped with direct sensors in two diagonally opposite tires and also includes a 4-wheel indirect system. Compared to a full direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data of the actual pressure in all four tires like a direct system.
