after repair, do you have to do a drive cycle?

Question

the 0400 code is gone but still have yellow light on my innova 3100 code reader.

Answer 1

Is the code pending? if the problem was fix it there should be no codes, and if you reset the light you have to do a drive cycle on most Nissan's I would say from experience drive at least 10-15 miles on the freeway at 60mphs and 5-10 miles regular street driving.
