AC problem w code and readings
Blowing hot after fixing the panel. The great local indy here says new compressor and clutch but wanted to get your thoughts.
I have a 1232 refrigerant pressure sensor error and my readings are as follows.
1 113
2 142
3 107
4 106
5 104
6 198
7 38
8 116
9 0
10 .8
20 19.0
21 6
22 0
23 0
24 14.2
40 8
41 5
42 200
43 14
Any thoughts? Read where I could bypass the pressure sensor and that may work. How would one do that?

First try to clear the code by pressing and holding both AUTO buttons for about 5 seconds. Restart the car - compressor may kick just enough to get a reading of the number 7 diag. This will determine if the compressor is pumping enough to get a bar reading in the 12-13 range.
You will need to have the sensor replaced to get the compressor to run. I don't think you can just jump it - but I may be wrong. Its digital so the reading will trip the computer if out of range. Yes the system has to be evac'd to get a new sensor installed at the drier.
The indy thinks you need a new compressor because it can't kick on because the code. Unfortunately unless it can be jumped or you can get a quick reading before it kicks out the only way to get a proper diag is to replace the sensor - get it regassed and then check the compressor. Kind of a pain - but they should have done this before determining that a compressor is in order.

Thank you so much for y'all's help.
Is this the correct part?
