The float in the tank might be leaking and since it has gas in it, its showing empty.

sounds like you may have a bad fuel level sender problem. as for the check engine light coming on and storing a fault code that is a separate issue.

Why fuel gauge not working gas guage on 2009 santa fe stays on empty even with a full tank of gas. Guage fluctuates from empty to 3/4 full to empty to 1/3 full at any given time.


It could be the sending unit in the tank or the gauge on the dash. A mechanic would test the signal coming from the sending unit to verify.

My gas guage stays on empty and the tank is full


Sounds like your senor in the gas tank it self is bad. Most cars have a float that read out how full the tank is and when it goes out it will stay stuck showing you on the dash that your tank is empty even though it is full.

I have a 2004 pontiac montana. for about two years the fuel guage would fold over and read 125 degrees when the tank is full. it woulld stay there until tank was empty and the needle would drop to empty,...


It could be a bad fuel gauge in the dash unit, but....
Usually it's "The bad".
The fuel level sending wipe arm and windings on the fuel sender wear and send erratic readings.The only cure is a replacement fuel gauge sender.
The check engine light should not be related to the erratic fuel readings.
"The good".
If you have over 200,000kms or 120,000 miles on your van you need a new fuel pump anyway,so have a complete assembly put in which will have a new fuel sender on it.
