Volvo: Engine Light, p0442, tank system

Question
My check engine light came on.  I took car to AutoZone to check for engine trouble codes.  2 codes came on but they couldn't read because they were manufacture codes.  AutoZone gave me the codes.  They are P1081 & P0442.  Can you please tell me what they mean.

Thank you!

Answer
Ruby,
The codes you supplied are generic not manufacture, and P1081 I can't find.
PO442 on most model year cars means leakage tank system. That is the system that retains the fumes and stores them in the canister to burn the fumes as the engine runs.
Have a shop that works on Volvo read the codes and see what they are.
