What does Porsche TPMS malfunction mean?

[LeEliza]

TPMS malfunction refers to a Tire Pressure Monitoring System failure. The illumination of this warning light alerts the driver to abnormal tire pressure, which may be caused by insufficient pressure in one of the tires. It is advisable to check the tire pressure as soon as possible. Increased fuel consumption with low tire pressure: When a car's tire pressure is too low, the most noticeable effect is an increase in fuel consumption. This occurs because low tire pressure increases friction between the tires and the road surface, thereby increasing rolling resistance and leading to higher fuel consumption. Low tire pressure increases risk of blowouts: Additionally, the operational stress on the tires increases. The heightened friction causes the tires to heat up, making them softer and reducing their structural integrity. Maintaining high speeds for prolonged periods under these conditions may even result in tire blowouts, posing a serious safety hazard. Tire pressure values: Normal tire pressure typically ranges between 230-250 kPa (2.3-2.5 bar). Tires require precise inflation pressure to function optimally—both underinflation and overinflation are detrimental.
