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

The throttle position sensor (TPS), which is located in the i20, can become damaged. This sensor is responsible to measure the opening angle of throttle valve. This information is transmitted to an electronic control unit, which is used to calculate the amount of fuel required. A malfunctioning throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and a reduction in engine performance.

Transmission problems are another common issue for i20s. The transmission is a complex component that has many gears that connect to transfer power from the engine. As time passes the friction between gears could cause the transmission to suffer failure. Sounds of grinding or clunking as well as the jerky acceleration can be signs of the gearbox being damaged.

The spark plugs inside the i20 are a second common problem area. Spark plugs that are defective could cause engine damage due to not giving enough sparks to each cylinder. If not checked a damaged spark plug can result in severe and costly engine damage.
