The data is sent to an electronic control unit, which helps calculate the amount of fuel needed. A malfunctioning throttle position sensor will result in a decrease in engine performance, jerky acceleration, and RPM fluctuations when driving.

Another issue common to the i20s is the transmission that is defective. The transmission is a complex component that has many gears that connect to transfer the power from the engine. The friction between the gears causes wear over time which can cause the transmission to fail. The sound of grinding or clunking and jerky acceleration are symptoms of an unreliable gearbox.

Spark plugs are an additional issue for the i20. A defective spark plug can damage the engine by not delivering the right amount of sparks to every cylinder. A damaged spark plug could cause costly and serious engine damage if it is not checked.
