Why do I have ???? Four Question Marks on Oil Pressure gauge readout?
The oil light came on-never happens. Oil is clean and crank case is short only
0.5 qt. On the "Driver Information Center" the readout for oil pressure is four
question marks. Drove it home, 4 miles with no knocking et al. What is the
"????" trying to tell me?
pressure sensor could be bad.
