I had a problem with my car before
my idle was really low, it was caused
by the P0505 my Idle Sensor was bad..
So I replaced it.. my Idle was no longer
Low no more I then deleted the Code
with my Scanner, but the Code Kept
coming back:/ the car was off..
Idk whats up with this car????

 

P0505 DTC code which refers to a malfunction of the IAC (Idle Air Control) system, I don't think scanner alone can't remove it try to think of other ways :P

 

there might no available local dealership for Nissan near their place.
