The data is sent to an electronic control unit, which helps calculate the amount of fuel needed. A malfunctioning throttle sensor will cause rapid acceleration that is jerky, fluctuations in RPM and decreased engine performance.

Transmission issues are another frequent issue in the i20s. The transmission is a complicated part that has a lot of gears which mesh together to transfer the power from the engine.
