Why is the solar tire pressure gauge not displaying?
2 Answers
Continuous rainy days cause the solar pressure gauge to malfunction. The main reasons for the problem and solutions to address the failure are as follows: Main reasons for the problem: The solar gauge operates by maintaining its function through solar light exposure. Its working principle involves the solar panel converting sunlight into electrical energy, which is then stored in the battery. During continuous rainy days, there is no light to convert into electricity, so the battery does not receive additional power. Meanwhile, the monitor continues to consume power to maintain operation. When the stored power is depleted, the monitor stops functioning. Solutions to address the failure: It is best to add auxiliary power sources such as electricity or air, which will allow continued use.
I've encountered this issue several times during long-distance drives. The solar-powered tire pressure monitor not displaying could be due to the solar panel being covered by dust or dirt, preventing it from charging, which leads to the battery draining and the screen going black. It might also be a sensor problem, such as it becoming loose or getting dirty from mud or water on the road, making it unable to read data. I remember last time my car was parked in an underground garage for over a week, and due to insufficient sunlight, it didn't charge; after I wiped it clean and left it in the sun for half an hour, it recovered. It's recommended to regularly clean the solar panel and sensor area, and avoid parking the car in shaded areas for extended periods. If it still doesn't work, check if the battery needs replacement or try restarting the device—some models can be reset by holding down a button. For safety, manually check the tire pressure as soon as possible to avoid false alarms affecting your driving.
