CEL(P1477?) after oil separator valve R&R
Replaced oil separator valve. No foghorn sound now but got the CEL (P1477 ?) instead.
This is what Peake research tool tells me: EVAP LDP reed valve cant open.
I am not inclined to believe it is a coincidence, hence the question: What could have I screwed up?
