Fault Diagnosis

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

One of the most common problems with i20s is the throttle position sensor (TPS) is damaged. This sensor is accountable 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 required. A problem with the throttle position sensor could result in a decrease in engine performance, jerky acceleration and RPM variations when driving.


Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complex component that has many gears that connect to transfer power from the engine. In time, the friction between the gears can cause the transmission's failure. The sound of grinding or clunking and an acceleration that is jerky can indicate an unreliable gearbox.

Spark plugs are yet another issue for the i20. Faulty plugs could cause engine damage due to not providing enough sparks to each cylinder. A damaged spark plug could cause costly and severe engine damage if not properly checked.
