2005 Nissan Altima 2.5L - where is the heated oxygen sensor number 2 located

Oxygen sensors are mounted either side of the catalytic converter. Number 1 is mounted before the cat in the down pipe and the Number 2 is in the exhaust pipe just after the cat, think the number 2 is the downstream.

Altima code 507

507 is a catalytic converter code that the computer throws when the oxygen level is below 95% of max. Altima's don't generally have that issue so i would lean more towards an 02 sensor. usually its the upper 02 sensor. start there.

Dies after you drive it a little while could it be the oxygen sensor on it ? if so where is it located on a 1993 ?

I would change the oxygen sensor only if the oxygen sensor code comes up showing that the o2 sensor is is not cycling.

Have the car scanned in order to determine what may be causing the stall condition.
