The throttle position sensor (TPS) located in the located within the i20, may be damaged. This sensor is responsible to determine the opening angle of the throttle valve. The information is then sent to the control unit, which helps calculate the amount of fuel needed. A problem with the throttle position sensor could result in reduced engine performance, jerky acceleration, and RPM fluctuations when driving.

Transmission problems are another common issue in i20s. The transmission is a complicated component with many gears that mesh together to transfer power from the engine to the wheels. In time the friction between the gears can lead to transmission failure. Signs of a defective transmission include clunking or grinding noises and rapid acceleration that is jerky.

The spark plugs of the i20 are a second common problem area. Spark plugs that are defective could cause engine damage due to not sending enough sparks to every cylinder. A damaged spark plug can cause expensive and serious engine damage if it is not checked.
