What to Do When the Tire Pressure Monitoring System Warning Light Comes On?
2 Answers
Solutions for when the tire pressure monitoring system warning light comes on: 1. The driver should stop and check if there is any issue with the tires; 2. Check the tire pressure to determine if it is a false alarm. If it is a false alarm, locate the SET button to reset the tire pressure and manually turn off the tire pressure monitoring light; 3. Use a tire pressure gauge to check the tire pressure. If the tire pressure is abnormal, restore the tire pressure to the standard level; 4. Check if there is any issue with the car's sensors; 5. Visit a nearby auto repair shop or 4S store for inspection and repair. The tire pressure monitoring system warning light coming on indicates that the current tire pressure deviation among the four tires is too large or the tires are underinflated, meaning there is an issue with the vehicle's tire pressure that needs to be checked and resolved as soon as possible.
When the tire pressure monitoring light comes on, I immediately find a safe place to pull over and avoid rushing back on the road to prevent risks. First, I use a tire pressure gauge to manually measure the pressure of each tire, including the spare. If the readings are low, it might be due to a tire leak or temperature changes causing thermal expansion and contraction. If the readings are normal but the light is on, the sensor battery might be depleted, causing a false alarm. When handling it myself, I check the owner's manual for reset instructions, such as holding a dashboard button for a few seconds. Common reasons for the light include tire wear, aging, or system module failure. Developing a habit of checking tire pressure monthly with a digital tire pressure gauge ensures better accuracy, as improper pressure can increase fuel consumption. If the light stays on, don’t delay—visit a professional repair shop to scan for issues with diagnostic tools. Safety is more important than saving money.
