it means you have an implusible fuel level signal, sholdn't have anything for the smog failure. thing to do for that is change oil and oil& air filters, drive the car for about 15 miles on eway if possible then take it in for a check it will probably pass.for the 1403 it can be a bad pcm, front control module or cluster module or short in wire. have apro check it with ascanner they can do a better job diagnostics with it. if it fails again then it's maybe a pcm, but not necessarily.
