Diagnosis of a Fault

If your check engine light is on and an error code is visible, it can be difficult to pinpoint the problem without the use of a diagnostic scanner commonly called an OBD 2. These are available in Bluetooth versions which connect to your phone, or standard models with an attached reader.

The throttle position sensor (TPS) is located in the i20, can be damaged. This sensor is responsible to determine the opening angle of throttle valve. This information is passed to the control unit and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle sensor could result in abrupt acceleration, erratic RPM changes and a reduction in engine performance.

Another issue that is common in i20s is the faulty transmission. The transmission is a complex component made up of many gears that connect to transfer power from the engine to the wheels. The friction between the gears causes wear and tear that can cause the transmission to fail. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.

Spark plugs are another issue for the i20. Spark plugs that are defective could cause engine damage due to not giving enough sparks to each engine. A damaged spark plug could cause expensive and serious engine damage if left unchecked.
