Troubleshooting

One of the most common issues with i20s can be that the throttle position sensor (TPS) becomes defective. This sensor is accountable to determine the opening angle of the throttle valve. The data is sent to an electronic control unit, which contributes to the calculation for the amount of fuel required. A malfunctioning throttle sensor will cause sudden acceleration, RPM fluctuations and a reduction in engine performance.

Another issue that is common in the i20s is the malfunctioning transmission. The transmission is a complex component made up of many gears that interlock to transfer power from the engine to wheels. The friction between the gears can cause wear over time which can cause the transmission to fail. The sound of grinding or clunking and an acceleration that is jerky can indicate an inefficient gearbox.

Spark plugs are yet another issue for the i20. Faulty plugs could cause engine damage due to not giving enough sparks to each cylinder. If not checked, a damaged spark plug can cause serious and costly engine damage.
