Fault Diagnosis

If your check engine light comes on and the fault code is present, it can be difficult to identify the problem without the use of a diagnostic scanner, commonly called an OBD 2. These can be purchased in Bluetooth versions which connect to your smartphone, or standard models that come with an OBD 2 reader.

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

Transmission problems are another common issue with the i20s. The transmission is a complicated part with a variety of gears that interlock to transfer power from the engine to the wheels. The friction between the gears causes wear and tear, which can cause the transmission to fail. The sound of grinding or clunking and the jerky acceleration can be signs of the gearbox being damaged.

Spark plugs are an additional area of concern for the i20. The problem with the plugs is that they can cause damage to engines by not delivering enough sparks to every cylinder. If left unchecked a damaged spark plug could result in serious and expensive engine damage.
