One of the most frequent issues with i20s can be that the throttle position sensor (TPS) is damaged. This sensor is responsible to determine the opening angle of throttle valve. This information is passed to the control unit and contributes to the calculation of the amount of fuel required. A malfunctioning throttle sensor will cause rapid acceleration that is jerky, fluctuations in RPM and a reduction in engine performance.

Another common problem found in the i20s is the transmission that is defective. The transmission is a complex component made up of many gears that connect to transfer power from the engine to wheels. The friction between the gears leads to wear over time which can cause the transmission to fail. The sound of grinding or clunking and an acceleration that is jerky can indicate the gearbox being damaged.
