Question

Will having a P1615 fault code on a 2004 Nissan Sentra cause me to fail an emissions test?

Answer 1

This code specifically is for the immobilizer system and should not cause any issue with the emissions test. Also, in most cases it should not cause your check engine light to be on either.
