Why are my gauges reading wrong?

So, the fuel sending unit is an important component of the car's fuel system, as it is responsible for accurately measuring and communicating the amount of fuel in the tank to the dashboard. It works by using a float attached to a variable resistor that moves up and down with changes in fuel level. This movement alters the resistance of the resistor, which then sends an electrical signal to the gauge cluster on your dashboard. If this component isn't working correctly, then you won't get an accurate reading from your car's fuel gauge. A bad or worn out sending unit can cause low or intermittent readings, or your gauge may read empty even when there is still plenty of gas in your tank! In order to fix this issue, you must replace or repair your vehicle's fuel sending unit so that it can once again measure and communicate accurate levels of gasoline to your driver information center.

Does the ECU control the instrument cluster?

While advancements in car technology have made automobiles more efficient and reliable, the complexity of modern cars requires sophisticated monitoring systems.
