The fuel gauge may not read correctly and/or the Check Engine Light may illuminate with code P0455/P0461 stored for a fuel level sensor issue. These faults may be caused by a fuel vapor line inside the fuel take interfering with the fuel level sensor. If this is found to be the case, repositioned and securing the vapor line should correct this concern. If no fault is found with the fuel vapor line, the fuel level sensor itself may be at fault.Google+

Filled tank and fuel gauge did not seem to register. Turned car off and back on and it registered a full tank. Shortly thereafter while sitting in traffic the fuel gauge dropped to empty and check engine light came on. Never had this problem before. Up until now I have been very lucky with minimal repairs required.

My fuel gauge drops to empty and the check engine light comes on after filling up. Used to fix it by tightening the fuel cap extra tight (20 or so clicks while pushing in hard). Then just replaced fuel cap with AC Delco GT283 fuel cap and no more problems. Check engine light went out after a few miles of driving with the new cap.

I have a full tank but my gauge always says empty an my gas light is always on...
Code P0463- Poor electrical connection at the fuel level sending unit. Engine light came on and went off every time my gas was low in car. Now it stays on and my gas gauge will go up and down all the time.
