OK, so I know that the numbers pulled correspond to the following list but does anyone know what the correct reference ranges are for some of this chart?

01 In-car temperature sensor.
02 Outside temperature sensor.
03 Heater core temp, left.
04 Heater core temp, right.
05 Evaporator temperature sensor.
06 Engine coolant temperature.
07 Regrigerant pressure in bar (e.g. '4' is 4 bar).
08 Refrigerant temperature.
09 Not used.
10 Heater blower control voltage (normal 08-6.0, meaning .8 to 6 volts).
11 Emissions sensor voltage (to detect atmospheric gases and recirculate interior air).
12 Sun sensor voltage (to shift airflow in car).
20 Control current for auxilliary fan (electric fan on radiator, given in milliamps or mA).
21 Engine speed (x100).
22 Road speed (km/h or mph depending on installation).
23 Battery voltage at terminal 58d (as a percentage of total voltage, e.g. 99.0 = 99%).
24 Battery voltage (e.g. 12.8 = 12.8V).
40 Climate control software version.
41 Climate control hardware version.

I pulled the sun sensor code, Eb1 234

and had the following numbers:

1. 78
2. 71
3. 78
4. 76
5. 75
6. 172
7. 05
8. 82
9. 30
10. 1.4
11. 4.0 and on second check, 2.9
12. 4.3
20. 3.2
21. 40
22. 00
23. 32
24. 13.3
40. 164
41. 32
42. 72
43. 152
