First, take note of the way that the old battery sits inside the circuit board or snap a picture. This will enable you to put the new battery in the same spot. Water Damage The key fob features rubber seals to shield the chip's electronics from water. If it can withstand an accidental splash of water from a washing machine, or a brief submersion in light rain, it's unlikely to get damaged.

These are available in Bluetooth models that connect to your smartphone, or standard models with an integrated reader. The throttle position sensor (TPS), which is located within the i20, may be damaged. This sensor is responsible for measuring the opening angle of the throttle valve. This information is passed to the control unit and contributes to the calculation of the amount of fuel needed. A damaged throttle sensor can result in rapid acceleration that is jerky, fluctuations in RPM and reduced engine performance. Transmission issues are another frequent issue with the i20s. The transmission is a complicated component that has many gears that work together to transfer power from the engine to the wheels. The friction between the gears leads to wear and tear that can cause the transmission to fail. Grinding or clunking sounds and an acceleration that is jerky can indicate an inefficient 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 by not delivering the right amount of sparks to the cylinders. If not checked, a damaged spark plug can cause serious and expensive engine damage.
