Why is the solar tire pressure gauge not displaying?

[DeBriella]

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.

I enjoy tinkering with automotive electronic accessories myself, and I believe the reasons for tire pressure monitors not displaying often lie in power and signal issues. The solar charging component is prone to failure, such as aging batteries that can't hold a charge or running out of power during cloudy days with weak sunlight. If the sensor is damaged or has poor contact, data can't be transmitted to the display. I've helped neighbors fix similar situations, and the solution is straightforward: first, clean the solar panel and sensor with a soft cloth, then ensure they're exposed to sunlight for a few hours to test. If the battery voltage is low, you might need to replace the battery or check for internal circuit shorts. Some models require re-pairing with Bluetooth or the car's system—look for a reset option in the settings menu. Regular maintenance should avoid extreme weather conditions to prolong the device's lifespan.

I know this well. Solar-powered tire pressure gauges commonly fail to display in three scenarios: first, when the solar charging fails, leaving the device without power—this happens if the car is parked in the dark for too long; second, when the sensor is dirty or damaged and can't read the pressure; third, when the display itself malfunctions or has loose wiring. The solution is simple: first, clean the device and place it in sunlight to recharge, then press the reset button a few times. If that doesn’t work, you might need to replace the part. Safety is no joke, so immediately check the tire pressure manually to ensure driving stability.
