Verified for the Pontiac G6

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.

The 30amp high speed cooling fan fuse may blow due to high start up loads associated with the high speed cooling fan motor. Our technicians tell us the high speed cooling fan wiring and fuse should be upgraded to a 40amp circuit to correct this concern. The fan wiring MUST be upgraded along with the fuse to handle the increased current flow.
