What does TPMS fault mean?
2 Answers
TPMS fault refers to a Tire Pressure Monitoring System malfunction. When this warning light illuminates, it alerts the driver to abnormal tire pressure, which may be caused by low pressure in one of the tires. The tire pressure should be checked as soon as possible. If the TPMS warning light comes on while driving, immediately reduce speed and avoid sharp steering or sudden braking. Then, check the tire pressure, inflate all four tires to the proper level, and press the tire pressure reset button to clear the warning. Tires are circular elastic rubber products mounted on metal rims that support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance.
The first time I saw the TPMS warning light come on was on the highway, and it scared me so much that I immediately pulled over. TPMS stands for Tire Pressure Monitoring System, and a fault indicates there's an issue with it, possibly due to sensor battery depletion or signal interference. When I took it to the repair shop for inspection, the mechanic said the sensor batteries typically last about 5-7 years and need replacement. This fault affects safety, as low tire pressure increases the risk of a blowout, especially during long trips. It's recommended to first use a tire pressure gauge to check each tire's pressure yourself. If all readings are normal, it might be a false alarm; if not, go to a professional shop immediately and don't delay. I've since developed the habit of checking my tire pressure monthly to avoid similar troubles, making my drives much more reassuring.
