This information is passed to the control unit and is used to the calculation of the amount of fuel required. A malfunctioning throttle sensor can cause rapid acceleration that is jerky, fluctuations in RPM and decreased engine performance.

Transmission problems are a common issue in i20s. The transmission is a complicated component that has many gears that connect to transfer power from the engine to wheels. The friction between the gears can cause wear and tear that can cause the transmission to fail.
