Can someone make sense of these readings...
01 In-car temperature sensor............................................ .... 25,5
02 Outside temperature sensor............................................ ..30
03 Heater core temp, left. .................................................. . .16
04 Heater core temp, right............................................. .......16
05 Evaporator temperature sensor. ........................................15
06 Engine coolant temperature. .............................................84
07 Regrigerant pressure in bar (e.g. '4' is 4 bar). .....................11
08 Refrigerant temperature. ................................................ .44,4
09 Not used.
10 Heater blower control voltage (normal 08-6.0, meaning .8 to 6 volts). 3.9
11 Emissions sensor voltage........................................... ...... 28%
12 Sun sensor voltage (to shift airflow in car)..............jumps between 50-70
20 Control current for auxilliary fan (electric fan on radiator, given in milliamps or mA). .................................................. ...................40%
21 Engine speed (x100). .................................................. ......540 min
22 Road speed (km/h or mph depending on installation). ..............0
23 Battery voltage at terminal 58d (as a percentage of total voltage, e.g. 99.0 = 99%). .................................................. ......................0%
24 Battery voltage (e.g. 12.8 = 12.8V). ....................................14
40 Climate control software version. ..........................................ZU
41 Climate control hardware version.......................................... ZU


The system is not running good. if the sun is out or I stop for a light it turns worm to unbearable inside.
rechargerd the system and replaced the sun sensor...no difference....
Please help...thanks

 

my low pressure is 45 and my high is 125. at 80 deg the high should be about 200. can anybody tell where to look for the problem?
