This information is transmitted to a control unit, which helps calculate the amount of fuel needed. A malfunctioning throttle sensor will result in abrupt acceleration, erratic RPM changes and decreased engine performance.

Transmission issues are another frequent issue for i20s. The transmission is a complex component that has many gears that work together to transfer power from the engine to wheels. In time the friction between the gears can cause the transmission's failure. Symptoms of a faulty transmission include grinding or clunking noises and jerky acceleration.

Spark plugs are yet another area of concern for the i20. A defective spark plug can damage the engine because they do not deliver the correct amounts of sparks to every cylinder. A damaged spark plug could cause expensive and serious engine damage if left unchecked.
