Troubleshooting

These are available in Bluetooth versions that connect to your phone or standard models that have an OBD 2 reader that is connected to the socket.

The throttle position sensor (TPS) located in the located in the i20, can be damaged. This sensor is used to measure the opening angle of throttle valve. The information is then sent to the control unit, and contributes to the calculation of the amount of fuel required. A malfunctioning throttle position sensor could cause a reduction in engine performance, jerky acceleration, and RPM variations when driving.

Transmission problems are another common issue for i20s. The transmission is a complicated component that has many gears that connect to transfer power from the engine to the wheels. In time friction between gears can lead to transmission failure. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.

Spark plugs are a different area of concern for the i20. A defective plug can cause engine damage through not sending enough sparks to every cylinder. If they are not checked an unclean spark plug could result in serious and costly engine damage.
