The throttle position sensor (TPS) located in the located within the i20, may be damaged. The sensor is responsible for measuring the opening angle of the throttle valve. G28 Car Keys is passed to the control unit, and contributes to the calculation of the amount of fuel required. A malfunctioning throttle position sensor could result in a decrease in engine performance, jerky acceleration, and RPM fluctuations while driving.

Transmission issues are another frequent issue with i20s. The transmission is a complicated component that contains a number of gears which mesh together to transfer power from the engine. Over time friction between gears could cause the transmission to suffer failure. Clanging or grinding sounds as well as the jerky acceleration can be signs of an unreliable gearbox.

Spark plugs are another issue for the i20. A defective spark plug can damage the engine by not delivering the correct amounts of sparks to every cylinder. If not checked an unclean spark plug could result in serious and costly engine damage.
