Error Codes:
B1227 Outside temperature indicator temp sensor (014)
B123 (didn't get the last digit) could be:
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)
E FF means no more error codes found.
Of those codes, I believe only 1232 or 1233 would be the only ones that would prevent the compressor from engaging. I'm definitely not an A/C expert, so I'm sure someone will correct me if I'm way off base.
For the real time data: (Assuming all temperature values are in deg F.)
#1 is inside temp: 72 (probably OK)
#2 is outside temp -40 (an improbable value. Sensor is bad. B1227 code above)
#3 is left heater core temp: 110 (OK)
#4 is right heater core temp: 111 (OK)
#5 is evaporator temp: 64 (probably OK if compressor is not running)
#6 is engine coolant temp: -40 (an improbable value)
#7 is refrigerant pressure in bars: 4 (probably OK if compressor is not running)
#8 is refrigerant temperature: 58 (probably OK)
