If you get DTC code P0171 or P0172 then It could be Mass Air Flow sensor gone BAD. Clean it or repalce it.
P1447 CODE IN MAXIMA , SANTRA, AND ALL NISSAN CARS MEANS // - GAS FUMES FROM GAS TANK TO EVAP VALUE // LEAKING IN SHORT GAS IS LEAKING(FUMES) ... .. SO CHECK FOR CRACK RUBBER HOSES AND REPLACE THEM... CODE WILL GO AWAY....
P0171, system too lean (bank 1). P0174, system too lean (bank 2). Start with checking for a vacuum leak.
In the manual for the 2000 Sentra, page EC-306, for DTC P0171, P0174 Fuel Injection System Function, it shows as possible causes: - Intake air leak - Heated oxygen sensor 1 (front) (bank 1) (bank 2) - Injectors - Exhaust fuel pressure - Lack of fuel - Mass air flow. I have read that the Mass air flow sensors are prone to fail on these cars, so you might want to have that checked first.
