Water Damage

The key fob is fitted with rubber seals that protect the electronic chip inside from water. If it is able to survive a quick splash from a washing-machine or an unintentional dip in a light drizzle, it's unlikely to be damaged. If you dropped it in an ocean or pool the water could get into the seals, damaging the circuit board. This is an expensive repair.

The first step is to dry the key fob completely. This can be accomplished in many ways. You can put it in a plastic bag and then cover it with silica gel bags that will draw the moisture out of it. Alternatively, you can use rice that has not been cooked, but it is important not to touch the key fob while it's still moist because this could contaminate the internal components.

Diagnostics of a fault

It isn't easy to pinpoint a problem if your check engine light comes on and you have a fault code. This is why an OBD diagnostic scanner is usually known as an OBD 2 (or OBD 2 in the UK).

One of the most common problems with i20s is that the throttle position sensor (TPS) develops a fault. The sensor is used to measure the opening angle of the throttle valve. This information is transmitted to the control unit, and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle position sensor can result in reduced engine performance, jerky acceleration, and RPM fluctuations when driving.

Another issue that is common in i20s is the faulty transmission. The transmission is a complex component with a variety of gears which mesh together to transfer power from the engine. The friction between the gears leads to wear over time which can cause the transmission to fail. Signs of a malfunctioning transmission include clunking, grinding noises and the jerky acceleration.

Spark plugs are yet another area of concern for the i20. Faulty spark plugs can damage the engine because they do not deliver the correct amounts of sparks to every cylinder. A damaged spark plug could cause expensive and serious engine damage if not properly checked.
