One of the most common problems with i20s is the throttle position sensor (TPS) is damaged. This sensor is accountable to determine the opening angle of the throttle valve. The information is then sent to the control unit that contributes to the calculation for the amount of fuel needed. A malfunctioning throttle position sensor can cause a reduction in engine performance, jerky acceleration, and RPM variations when driving.
Another problem that is frequently found in the i20s is the transmission that is defective. The transmission is a complex component that contains a number of gears which mesh together to transfer the power from the engine. Over time the friction between gears can cause the transmission's failure. The signs of a damaged transmission include clunking or grinding noises and an abrupt acceleration.
Spark plugs are another issue for the i20. Spark plugs that are defective can cause damage to the engine because they do not deliver the right amount of sparks to the cylinders. If they are not checked an unclean spark plug could result in serious and costly engine damage.
