Why does the Geely Emgrand GS keep alarming when the tire pressure is normal?

The reasons why the Geely Emgrand GS keeps alarming when the tire pressure is normal are: tire replacement without resetting the tire pressure module; tire puncture causing pressure changes; tire inflation without resetting the tire pressure monitoring; prolonged vehicle inactivity without tire inflation leading to low pressure. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Usually, an alarm is triggered when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply reset the tire pressure monitoring in this situation. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage issues, only replacement with a new part is the solution.
As a long-time owner of the Emgrand GS, I've also encountered the issue where the tire pressure alarm keeps going off despite normal tire pressure readings. Honestly, it's quite annoying—even though the tire pressure consistently measures around 2.5 bar, that warning light just won't turn off. I suspect it might be due to a dead TPMS sensor battery or a system calibration issue; these sensors on the Emgrand GS are prone to problems, especially after a year or two of driving. I first tried fixing it myself: pulled over, accessed the menu, and held down the reset button, but it didn't work. In the end, I took it to the 4S shop, where the technician diagnosed a weak signal from the rear wheel sensor. After replacing the battery, the issue was resolved immediately. If your car has the same problem, don't rush to replace parts. First, ensure the tires are fine, then prioritize getting a professional scan for error codes to avoid unnecessary expenses. During routine maintenance, mentioning a sensor check can help prevent future issues.
The tire pressure monitoring system (TPMS) on the Emgrand GS occasionally gives false alarms, triggering warnings even when the tire pressure is normal. This phenomenon is commonly caused by sensor malfunctions or signal interference. The wireless sensors used in TPMS are installed inside the tires to monitor air pressure changes. If the battery is low or the sensor is aging, it may send false alerts. I've also encountered cases where temperature affects the system—cold weather can cause the system to misjudge low tire pressure. The solution is simple: first, manually check the tire pressure to confirm it's normal; if that doesn't work, reset the system via the in-car settings menu. The Emgrand GS model has a TPMS reset button on the dashboard—try holding it down for a few seconds. It's advisable to regularly inspect sensor performance and replace the battery promptly if issues arise.
