What Causes the Tire Pressure Light to Illuminate?
2 Answers
The reasons for the tire pressure light to illuminate: 1. The tire pressure monitoring light may come on due to a punctured tire; 2. Sometimes the tire pressure monitoring light illuminates because the tire pressure is too high; 3. Driving for an extended period with low tire pressure can trigger the tire pressure monitoring light; 4. The tire pressure monitoring light may also come on if the tire pressure has dropped due to prolonged lack of inflation. When the tire pressure system alerts, first pull over safely and check the tire pressure of all four tires. If no obvious loss of air is visible, you can ignore it. After getting back in the car, reset the tire pressure system to turn off the warning light. Continue driving for a while. If the tire pressure warning light comes on again, it indicates that there is indeed a problem with the tire pressure of one of the tires, and it needs to be checked and repaired promptly.
When the tire pressure warning light comes on, it usually means your car is alerting you that the tire pressure may be below the normal value. This is often caused by a tire leak, such as a punctured nail or slow leak. A sudden drop in temperature can also cause the pressure to decrease, leading to a false alarm. If the light remains on despite normal pressure, the TPMS sensor may be malfunctioning, such as due to a drained battery or signal interference. My first recommendation is to pull over and check all tires with a simple tire pressure gauge, comparing the readings to the recommended values on the door frame. If the pressure is too low, inflate the tires to the proper level, and the light should turn off. If the issue persists, it's best to take the car to a repair shop and have a technician use professional tools to test the sensor circuit. Ignoring it is not an option—long-term low tire pressure can wear out the tire edges, increase fuel consumption by a few percent, and even lead to blowouts at high speeds, posing a safety risk. Therefore, timely action is crucial.
