They are available in Bluetooth models that connect to phones or standard models with readers that are connected to the socket.
The throttle position sensor (TPS) is located in the i20, can fail. This sensor is responsible for measuring the opening angle of the throttle valve. This information is sent to the control unit that helps calculate the amount of fuel required. A problem with the throttle position sensor could cause a reduction in engine performance, jerky acceleration, and RPM variations when driving.
Another problem that is frequently found in the i20s is a faulty transmission. The transmission is a complex component made up of many gears that work together to transfer power from the engine to wheels. The friction between the gears cause wear and tear, which can cause the transmission to fail. Signs of a defective transmission include clunking, grinding noises and rapid acceleration that is jerky.
The spark plugs on the i20 are a different common issue area. Faulty plugs can cause engine damage through not giving enough sparks to each engine. A damaged spark plug can result in costly and serious engine damage if left unchecked.
