The throttle position sensor (TPS), which is located within the i20, may fail. The sensor is responsible for measuring the opening angle of the throttle valve. The data is sent to the control unit, which is used to calculate the amount of fuel required.

The transmission is a complicated component made up of many gears that connect to transfer power from the engine to wheels. In time friction between gears can lead to the transmission's failure. Signs of a defective transmission include clunking or grinding noises and jerky acceleration.
