Fault Diagnosis

It isn't always easy to identify an issue if your check engine light is illuminated and you have a fault code. This is why an OBD diagnostic scanner is usually known as an OBD 2 (or OBD 2 in the UK). These are available in Bluetooth versions which connect to your phone or standard models that come with a reader attached.

The throttle position sensor (TPS) located in the located in the i20, could be damaged. The sensor is used to measure the opening angle of the throttle valve. This information is sent to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle sensor could result in sudden acceleration, RPM fluctuations and reduced engine performance.

Another issue that is common in the i20s is the transmission that is defective. The transmission is a complicated part that has a lot of gears that connect to transfer power from the engine. The friction between the gears can cause wear and tear that can cause the transmission to fail. Sounds of grinding or clunking as well as rapid acceleration that is jerky are signs of an inefficient gearbox.

Spark plugs are yet another issue for the i20. Faulty plugs could cause engine damage due to not sending enough sparks to every cylinder. If left unchecked, a damaged spark plug could cause serious and costly engine damage.
