Why does my gas gauge read full after a fill up?

When your fuel level is full, the electrical resistance at the sender changes, sends the signal to the gauge, and this is what causes the gauge to read as full after a fill-up. Depending on the level of electrical resistance, the fuel gauge changes to reflect the level of gas in the tank.

How does the resistance of a gas gauge change?

The fuel float contacts run on a potentiometer, or variable resistor, whose resistance changes depending on float level, effecting a change in output voltage. Some systems are wired so that high fuel level contacts the low-resistance section, gradually increasing resistance as fuel level drops.

What would cause a fuel gauge to peg way past full?

Re: What would cause a fuel gauge to peg way past full? Generally, if your gauge is reading past full and the tank isn’t full, it’s the positive wire that has a connection problem. If it’s reading totally empty, it’s the ground. If your tank if full of gas right now; I’d drive it for a while and see what happens.

Why would a gas gauge stop working?
