556393 Posted March 21, 2005 Report Share Posted March 21, 2005 TWICE IN THE LAST COUPLE OF MONTHS MY SERVICE ENGINE SOON LIGHT CAME ON IN MY `98 ELDORADO. PULL UP THE CODE 0463 WHICH SAYS IT IS " FUEL LEVEL SENSOR CIRCUIT HIGH VOLTAGE". CLEARED THE CODE AND THE SERVICE LIGHT WENT OFF. OK, WHAT DOES THAT CODE MEAN, WHAT IS STARTING TO FAIL? ANYONE WITH AN IDEA ON WHAT I NEED TO CHECK? THANKS. Link to comment Share on other sites More sharing options...
