Diagnostics of a fault
It isn't easy to pinpoint a problem if your check engine light is flashing and you have a fault-code.

These can be purchased 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, could become defective. This sensor is responsible to determine the opening angle of the throttle valve. This information is transmitted to the control unit that contributes to the calculation for the amount of fuel needed. A malfunctioning throttle sensor will result in abrupt acceleration, erratic RPM changes and a decrease in engine performance.
Another common problem found in i20s is the faulty transmission. The transmission is a complicated part with a variety of gears that mesh together to transfer power from the engine to wheels. The friction between the gears can cause wear and tear over time, which could cause the transmission to fail. The sound of grinding or clunking and an acceleration that is jerky can indicate an inefficient gearbox.
The spark plugs in the i20 are another common problem area. A defective spark plug can damage the engine by not delivering the right amount of sparks to the cylinders. A damaged spark plug could cause costly and severe engine damage if it is not checked.
