The car has no drivability issues just a random check engine light. This is the only code in the computer. I found a TSB for a computer software update. I have programmed a few other Nissans but what I wondering is if I purchased NERS over a year ago can I still use that software or do I need to get the latest version of NERS to reprogram this? Thanks!
Make sure the intake air boot between the maf and throttle body isn't torn in the folds
Yes, I've been using the same version of NERS for a few years now.
Yes, once NERS is purchased, then you pay per flash file. Under 20 bucks if I remember correctly.
I remember that tsb being dependent on pcm part # so look out for that also. But yes your ners should still be good
also there is an updated pcv valve for this problem, I reprogrammed 2 2013 altimas and code came back, changed pcv and it fixed the problem
What is the code setting criteria? Try being basic before getting exotic.
A dirty throttle body can also cause this code so make sure it’s clean
While some TSB's come later in the life cycle of a vehicle, most are within 24 months of production and are issued to fix a specific software issue. For example a bulletin issued back in the 90's on a 4L60E transmission. It opened of the shift timing protocol 50ms to cure a ghost gear ratio error. The bulletins are dated so we need to think past the desperation of looking for the proper repair…
Thanks for all the advise. I was able to program it with my current version of NERS. Also thanks for the other diag advise. It can be easy to jump to the software update instead of covering all the bases. Idid inspect the air boot and it was good. I didn’t inspect the throttle body or the pcv. I should have though, so thanks for the advice. I’ll remember that for next time.
