I am afraid I see no PO410 code or P0503 in the Nissan workshop manual for your car. PO410 refers to air injection system problems (I'm 90% certain the Maxima doesn't have air injection), PO503 is a vehicle speed sensor issue which I have seen fail on the Nissans but you loose speedometer and cruise control functionality.
