I have installed a new evap temp sensor and am now getting the following diagnostic readings:

01 = 98F
02 = 81F
03 = 91F
05 = 91F
06 = 177
07 = 03*.0
08 = 84F
09 = 50F
10 = 495
20 = 00
21 = 060
22 = 000
23 = 000
24 = 13.8
40 = 03
41 = 03
42 = 26
43 = 6-C
50 = 89F
51 = 60F
52 = 50
54 = OFF

From the above readings, it appears that my evap temp sensor reading has improved from what it was before (122), but it still seems to be running high. Please correct me if am wrong, but I believe I read somewhere on this forum that it should be running much lower.

Also, it appears that my a/c compressor is not kicking on because am still not getting cold air from my a/c. The R134a pressure is a little higher than it was before but that may be due to the 5oz or so I was able to pump into the system before the pressure indicator climbed close to the yellow line on my pressure indicator gauge.

My question then is this; why is the compressor not kicking on and what can I do to correct that and get an ON reading from #54 above? Am I getting a wrong R134a pressure (content) reading due to a faulty pressure gauge? And, shouldn't the refrigerant pressure bar be higher than 03*.0 if the canister is really full? M.B.DOC or any other member out there that can , please help!
