Fuel Gauge

The fuel gauge shows how much fuel is in the tank, using a signal from the fuel level sender.

What is Fuel Gauge?

The reading is damped so it does not jump when fuel sloshes. Many cars show the level digitally and calculate the remaining range. Saddle-shaped tanks may use two senders. Recalibration is possible on some cars after sender replacement.

How it works

The instrument cluster converts the sender's resistance or data signal into a needle or bar display.

Why it matters for your car

A sticking sender can show a wrong level and lead to running out of fuel. Do not rely on the last part of the gauge, especially before long trips.
