Contacts

If your Hyundai key fob stopped working from the black and white, and you've still not lost it, you may be experiencing a malfunctioning internal chip.

Diagnostics of a fault

It isn't always easy to identify problems if your check engine light is flashing and you have a fault-code.

These are available in Bluetooth models that connect to your mobile or standard models with an OBD 2 reader that is connected to the socket.

One of the most common problems with i20s is that the throttle position sensor (TPS) is defective. The sensor is used to determine the opening angle of throttle valve. This information is sent to the control unit and is used to the calculation of the amount of fuel required. A malfunctioning throttle position sensor could result in lower engine performance, jerky acceleration, and RPM fluctuations during driving.

Another issue that is common in i20s is the faulty transmission. The transmission is a complicated component that has many gears that work together to transfer power from the engine. The friction between the gears cause wear over time which can cause the transmission to fail. Sounds of grinding or clunking as well as an acceleration that is jerky can indicate an unreliable gearbox.

Spark plugs are a different issue for the i20. The problem with the plugs is that they can cause engine damage by not sending enough sparks to every cylinder. A damaged spark plug could cause expensive and serious engine damage if it is not checked.
