That is great info. Your pressures are pretty much equalized which is normally indicating that the compressor is not operating properly. The fact that you noticed it is staying engaged is another sign, as you noted. That is staying that way because the PCM is not seeing the pressure change so it is keeping the compressor engaged to try and achieve that. So if those pressures where with the compressor running then it is not building pressure.
Take a look at the attachment. If you had a clogged expansion valve you would have pressures like 200/70 because even though there is a restriction, your compressor would still create a pressure difference. This indicates the compressor is not building pressure. If it is coming on and engaging then the compressor is faulty.
