In this video I am diagnosing a P0455 EVAP system leak detected on a Chrysler 300.
Found that the evaporative emissions vent valve in the right rear inner Fender had failed. The vent valve is connected to the evaporative emissions canister. And the right rear inner Fender has to be removed to gain access to it.
On this Chrysler 300 it was relatively easy to test the EVAP vent valve. Once we reinstalled the new one I ran an EVAP leak test with the diagnostic scanner and the vehicle past verifying the repair was complete.
This video will show you how to test an EVAP vent valve which is the most common cause of a p0442, p0445 and P0456.
Evap vent valves, or close valves, as some people call them, are by far the most common cause of evap leaks, so I would always check your canister vent valve first.

The Engine Control Module (ECM) duty-cycles the oil control valve to control oil pressure to the intake camshaft sprocket to vary the intake valve timing. Low engine oil or poor vehicle maintenance also cause this problem. Found oil very low and dirty. Did bg oil flush and oil change.
