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!

They need to verify the sender is sending the correct voltage to the
ecm. As long as the sender is working and there is no wiring issue,
the ecm is at fault.

Fuel Level Sensor A Circuit Intermittent. This is the deffintion for
the code, so I would suspect a loose or corroded connector at the
sender or upstream from there. Your mechanic needs to see if your
getting constant voltage at the sender wire.
