models that have a reader attached to the socket The throttle position sensor TPS, which is located in the i20, can become defective This sensor is responsible to determine the opening angle of the throttle valve The data is sent to a control unit, which is used to calculate the amount of fuel needed A problem with the throttle position sensor could result in lower engine performance, jerky acceleration and RPM fluctuations during driving Another problem that is frequently found in the i20s is a faulty transmission The transmission is a complex component with a variety of gears that connect to transfer the power from the engine In time the friction between the gears can lead to the transmission's failure Grinding or clunking sounds and the jerky acceleration can be signs of a faulty gearbox Spark plugs are an additional aspect to be concerned about for the i20 Spark plugs that are defective can cause damage to the engine because they do not deliver the right amount of sparks to every cylinder A damaged spark plug could cause costly and serious engine damage if left unchecked
