Troubleshooting

If your check engine light comes on and a fault code is present it may be difficult to determine the issue without the help of a diagnostic scanner, often referred to as an OBD 2. They are available in Bluetooth models that connect to your smartphone, or standard models with an attached reader.

The throttle position sensor (TPS), which is located in the i20, can become defective. This sensor is responsible to determine the opening angle of the throttle valve. This information is transmitted to the control unit and contributes to the calculation of the amount of fuel required. A problem with the throttle position sensor could result in a decrease in engine performance, jerky acceleration, and RPM fluctuations while driving.

Transmission issues are another frequent issue in i20s. The transmission is a complicated component that has many gears that mesh together to transfer power from the engine to wheels. The friction between the gears can cause wear and tear that can cause the transmission to fail. Signs of a malfunctioning transmission include clunking, grinding noises and an abrupt acceleration.

Spark plugs are yet another aspect to be concerned about for the i20. Faulty spark plugs can damage the engine by not delivering the correct amounts of sparks to each cylinder. If not checked the damaged spark plug can cause serious and costly engine damage.
