Automobile: 2001 Nissan Sentra Problem: While driving the car after a gasoline full-up the "Service Engine Soon" light came on, and would not shut off. I checked that the gas cap was tight and let the tank run down, and filled up again. Same problem. Brought the car into my mechanic who read the code--P0464. He replaced the 'Gas Tank Sender' and 'O-Ring.' However, the problem still exists. The car needs an inspection, and will not pass with the above condition.
Does anybody have any idea what's going on? Please Help!
