The Fuel Gauge May Not Read Correctly and/or Check Engine Light With Code P0455/P0461 on Chevrolet Malibu Maxx

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.
