Why does the tire pressure warning light remain on after a tire repair?

[LeJesse]

It indicates that the air pressure in the recently repaired tire is abnormal (usually overinflated). It must be adjusted to match the pressure of the other three tires. The tire pressure warning cannot be cleared manually. The vehicle's tire pressure warning system alerts when tire pressure is either too high or too low. It is recommended to check the pressure of all four tires. The standard tire pressure values are usually marked on the driver/passenger door edges or fuel cap, typically 2.2 bar for front tires and 2.4 bar for rear tires. After confirming all tires are properly inflated: 1. Use an OBD scanner to clear the fault code. 2. Drive at speeds above 30 km/h for some time to reset the system. Additional information: Tire pressure maintenance: Generally, car tires should be checked at least once a month. Seasonal adjustments are particularly important, with ideal times being November and May. In November when winter approaches, tire pressure usually decreases and should be slightly increased. In May when temperatures rise, check if pressures are normal. Note: Unless the tire pressure significantly exceeds standard range, avoid deliberately reducing pressure during this period.
