Here are the descriptions -

B1226 In-car temperature sensor (B10/4)
B1227 Outside temperature indicator temp sensor (014)
B1128 Heater core temperature (B10/1)
B1229 Heater core temperature (B10/1)
B1230 Evaporator temperature sensor (B10/6)
B1231 ECT sensor (B11/4)
B1232 Refrigerant pressure sensor (B12)
B1233 Refrigerant temperature sensor (B12/1)
B1234 Sun sensor (B32)
B1235 Emissions sensor (B31)
B1241 Refrigerant Fill

Since you know the fill is correct, if it were me I would replace the refrigerant temp/pressure sensor. They sometimes fail giving the same symptoms which you describe. The sensor is on the receiver/dryer located at the front/left of the engine bay.

It's unlikely that all of these codes mean problems. Often one or two codes tend to cause others since the electronics in the car is so interwined.

If you haven't done so you might also do a little search on A/C issues in the forum as well as checkout the stickies (permanent threads) at the top. Hope that helps some.
