Why is my gas needle floating?
Ray: Actually, you probably just have a faulty gas tank sending unit. There’s a float in your gas tank that floats down as the fuel level drops. As the float goes down, the metal contact attached to it slides down a variable resistor. And the contact’s point on that resistor tells your gas gauge how much fuel is left.
How much does it cost to fix a floating gas gauge?
The majority of the time it is the fuel gauge sender which is the problem. This part can be a bit pricey to repair and most of the expense is in labor costs. Depending on the make and model of your car and the specific sender that you purchase, costs will run on average between $250 and $800.
What is a floating gas gauge?
The fuel gauge sender is a component that is found in the gas tank of most road going vehicles. The sender float is designed to float on the surface of the fuel inside of the tank. As the level drops, the position of the arm and float will shift and move a resistor which controls the display on the gauge.

What causes the Check Engine light to illuminate?
The fuel level sensor can fail causing erratic or inaccurate fuel gauge readings. The Check Engine Light may also illuminate. Nissan has recalled 2006 – 2008 vehicles only for this fuel gauge issue.
Why does the Check Engine light stay on after filling up the gas tank?
Problem: When filling up the tank the fuel gage will still show as empty and then slowly rise to show full over the course of a day or so. The check engine light then comes on and stays on until the fuel gage shows the tank about half full. Just after that the needle drops down to show empty.
