What Causes the Car Tire Pressure Light to Illuminate?
2 Answers
When the car's tire pressure light illuminates, it indicates an issue with the vehicle's tire pressure, requiring the driver to stop and check whether the tire pressure is normal. Possible issues with tire pressure: Under normal circumstances, the tire pressure should be between 2.3-2.5 bar. If a tire is punctured and begins to leak, the pressure will gradually decrease. When it falls below the preset threshold, the tire pressure monitoring system will alert the driver. It is essential to stop and inspect the tire pressure as soon as possible, and if necessary, refill the air or replace the tire. Tire maintenance tips: Regularly check tire pressure and wear conditions, and promptly remove debris such as stones from the tire treads.
The car tire pressure warning light is on, and as an experienced car maintenance enthusiast, I often encounter this situation. The main reason is low tire pressure, which could be due to natural air seepage, a punctured tire, or a minor leak. Another common issue is a malfunctioning TPMS sensor; either a depleted battery or internal damage in the sensor can trigger the warning light. If the weather turns cold, the tire pressure may drop below the set range, or severe tire wear could affect the sensor readings. I once dealt with a car where the tire light kept coming on, and it turned out to be a failed sensor calibration that required a professional device to reset the system. It's advisable to first check the pressure of all tires and inflate them to the standard value; if the light remains on, then it's necessary to visit a shop to check the sensors or circuit issues. Don't ignore it, as it can affect driving safety, increase fuel consumption, and the risk of tire wear. Regular self-checks of tire pressure are the way to prevent this.
