Operation: Why does the check engine light come on?

Through this video tutorial we can understand why the engine warning light comes on. When the yellow light comes on, it indicates a less serious problem, however, when the red light comes on, it indicates a more serious problem, therefore the car should be stopped as soon as possible to avoid damage. The engine warning light comes on when one of the sensors, linked for example to the anti-pollution system, detects a fault (such as, for example, the turbine pressure being too low or too high, or the particulate filter clogged, etc.). If you turn off the vehicle's engine and start it again, and the light continues to stay on, the problem may be in the electronic system. If the light does not go off, the best thing you can do is go to a mechanic as soon as possible to carry out the diagnosis.

How to reset the TPMS on the Hyundai I20

On the steering wheel, among the right side controls, locate the control at the top left next to the "cruise" control.
