Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Did you do the APP sensor relearn and the Throttle Valve relearn procedures before doing the idle relearn
Outside of a defective throttle body out the box, I am not sure what else would cause it not to relearn. I will opt out and see if another expert knows
what procedure are you using are you using a scanner for your idle air volume relearn?
those are how you finish the procedure that method almost never works. also you need to make sure the transmission is warmed up to operating temp if able test drive the vehicle for about ten miles. they never put that into the manual about the trans temp but if it is not hot enough (above 160f ) then it will never set the idle relearn
that would be the best why to get that done. also the idle relearn usually will not set until all codes are cleared as well
not after 2004 they are held in the system until a scanner goes in and registers them as history codes so it can clear them.
if you have no further questions i would appreciate if you took a moment to leave me a rating.
