Troubleshooting

It can be difficult to diagnose the cause of a problem when your check engine light comes on and you have a fault-code. This is the reason why the diagnostic scanner is commonly called an OBD 2 (or OBD 2 in the United Kingdom). These are available in Bluetooth versions that connect to your phone or standard models with a reader attached.

The throttle position sensor (TPS), which is located in the i20 can become damaged. This sensor is accountable to measure the opening angle of throttle valve. The information is then sent to the control unit, which helps calculate the amount of fuel required. A malfunctioning throttle sensor could cause jerky acceleration, RPM fluctuations and decreased engine performance.

Transmission issues are another frequent issue in the i20s. The transmission is a complex part that has a lot of gears which mesh together to transfer the power from the engine. As time passes friction between gears can cause the transmission's failure. Grinding or clunking sounds and the jerky acceleration can be signs of the gearbox being damaged.

The spark plugs of the i20 are another frequent problem area. Faulty spark plugs can damage the engine by not delivering the correct amounts of sparks to the cylinders. If they are not checked, a damaged spark plug can result in severe and expensive engine damage.
