Camaro gas gauge problem, not reading right.

Hello Sara.

Well the way the gas its measured on the tank its with a float and a Potentiometer (variable resistor) that send the signal of the position of the float and the pot. Converts that signal in milivolts that actuate a needle on the instrument panel.

Sometimes that float "stuck" or fails, thats why your gauge its get false readings.

Track the level of your gas tank and compare it with the gauge.

Also an advise: try not run your car with less than a quarter of gas and not fill it all the way as soon as the pump disconnects stop pumping. (Your charcoal canister could get damage)

Good Luck!
