PO442 HC The only one that is "C" (current or still existing) is the fuel tank pressure. Check your gas cap to make sure the gasket is complete and clean. Put it back on and make sure it clicks several times.
The U1096 H, U1064 H, U1016 H come with the car at no extra charge! Those are always there when I check my car. My understanding is the trip level for thise codes is too critical and the slightest pulse. (Very short loss of communications) sets them off.
PO461 H is the left fuel level sensor. Since it only has an H code it cleared.
