If your check engine light is on and there is a fault code, it may be difficult to identify the issue without the aid of a diagnostic scanner, typically referred to as an OBD 2. They are available in Bluetooth versions that connect to your phone, or standard models with an integrated reader.

One of the most frequent problems with i20s is that the throttle position sensor (TPS) develops a fault. The sensor is responsible for determining the opening angle of the throttle valve. The information is then sent to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle sensor could result in jerky acceleration, RPM fluctuations and reduced engine performance.

Transmission issues are another frequent problem in the i20s. The transmission is a complicated component made up of many gears that interlock to transfer power from the engine to wheels. In time the friction between gears can cause the transmission's failure. Sounds of grinding or clunking as well as an acceleration that is jerky can indicate an inefficient gearbox.

Spark plugs are an additional aspect to be concerned about for the i20. The problem with the plugs is that they can cause engine damage by not sending enough sparks to every engine. A damaged spark plug could cause costly and serious engine damage if ignored.
