Water Damage

The rubber seals on the fob's key seal the chip's electronic components from water. Therefore, if it withstands a splash of water from a washer or an evaporation in light rain, it's not likely to be damaged. If you drop it into an ocean or pool the water could get into the seals, damaging the circuit board. This is a costly repair.

Troubleshooting

It isn't always easy to identify problems if your check engine light is illuminated and you have a fault code. This is why the diagnostic scanner is commonly called an OBD 2 (or OBD 2 in the United Kingdom). These are available in Bluetooth models that connect to your mobile 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 determining the opening angle of the throttle valve. This information is sent to an electronic control unit, which contributes to the calculation for the amount of fuel required. A malfunctioning throttle sensor could result in sudden acceleration, RPM fluctuations and a reduction in engine performance.

Another issue common to the i20s is the malfunctioning transmission. The transmission is a complicated component that has many gears that are connected to transfer power from the engine. 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 on the i20 are another frequent problem area. Faulty plugs can cause engine damage by not delivering enough sparks to every cylinder. A damaged spark plug can result in costly and serious engine damage if it is not checked.
