NTB-12-051I recommend reprogramming by nissan dealership
I have my service engine light on for a while. Need to smog truck but i cannot
because of it. Had it scanned and said it was the mass air flow sensor.
Replaced that reset the computer but then after a while of driving the light
came back up. Took it to a smog place where they ran a diagnostic and told
me this code popped up NTB-12-051i. they told me i would need to take it to
the nissan dealership to have it reprogrammed. Think it was sensor that needs
reprogramming. Well i called the dealership to setup a appointment. And he
wants to charge me 135 bucks for diagnostic. i already had one! the guy at the
smog said that the reprogramming should be free at the dealership. What
should i do?
