1998 V70 - AC- where is evaporator sensor ?

[Maestrours]

Hello,

I Come here as my problem seems to be exactly the same as described
After some time running my AC, (Which produces good cold air), my evaporator starts to freeze.

I have a 2000 v70 p80.

Here are m'y pressure values;
AT the charge port, compresser On:

AT idle, compresser off:

AT idle, compresser on:

Do you think i have too much gas?

What should be the values AT 25°C (77°F)?
Thanks a lot i'm pretty sure my issue is linked to gas pressure but cannot find a certain value for it...
