EVAP leak P0455 (vacuum cut valve-bypass valve test) - Nissan

In this video I will be showing you how to test for an EVAP system leak, using a smoke machine. Also we will be covering how to identify the normally open solenoid that is part of every EVAP system. This solenoid must be closed (all cars) either manually or with a scan tool before attempting to locate an EVAP leak.
