P0456 Code ???
Hi everyone...I am new to this Forum but have a "Check Engine" light which I have been unable to fix. My car is a 2011 Versa Hatchback with 94K miles on it...and I am very happy with it. Hope to keep it for another 100K if possible and reasonable.
The P0456 is a "very small leak in the evap system" which I am sure many of you have encountered. I have: replaced gas cap, replaced cannister vent valve, checked individual tubes with hand vacuum pump, checked cannister with hand vacuum pump and even had a smoke test done at Midas last week.
Also checked the purge solenoid valve with a hand vacuum pump and it hold vacuum in one direction (correct I think).
Have not been able to find that small leak.
So has anyone found a "very small leak" anywhere else in these systems ?
