Troubleshooting

It can be difficult to determine an issue if your check engine light is flashing and you have a fault code. This is why the diagnostic scanner is commonly called an OBD 2 (or OBD 2 in the UK). These are available in Bluetooth models which connect to your phone or standard models with readers that are connected to the socket.

The throttle position sensor (TPS) is located in the i20, can become defective. The sensor is responsible for measuring the opening angle of the throttle valve. The information is then sent to the control unit that is used to calculate the amount of fuel required. A malfunctioning throttle sensor will result in abrupt acceleration, erratic RPM changes and a reduction in engine performance.

Another issue that is common in the i20s is the malfunctioning transmission. The transmission is a complicated part that has a lot of gears that connect to transfer the power from the engine. Over time the friction between the gears can cause the transmission's failure. Symptoms of a faulty transmission include clunking or grinding noises and jerky acceleration.

The spark plugs of the i20 are a different common issue area. Faulty spark plugs can damage the engine because they do not deliver the correct amounts of sparks to each cylinder. If they are not checked, a damaged spark plug could cause serious and expensive engine damage.
