PO442 and PO455 codes

[Grusvag]

Any suggestions as to what might be triggering a couple EVAP Emission Control System codes?

PO442 is "EVAP Emission Control System (Small Leak) Leak Detected"
PO455 is "EVAP Emission Control System Gross Leak Detected"

A few days ago I also had the "Loose Gas Cap" light come on briefly.

Did you even search before creating this thread???

Gas cap???????????
N80 valve?????
Broken hose?

Also use a zero instead of an "O" when searching its its actually a zero

Check that your breather hoses are connected correctly.
