The reading for the evaporator sensor looks right, so that's probably not the issue. Reading #7 may be, but we don't know that one.

After clearing the codes, ensure that nothing came back right away.

As Steve says, it is difficult to tell how much refrigerant is in the system even with the best of gauges and with the compressor running. You don't have the best of gauges and the compressor isn't running.

That gauge is there to keep you from getting your suction pressure too high while you top it off. That's a quick way to kill your compressor.

If the compressor isn't running and there is no suction, you will always see a high pressure there if there is any liquid in the system. The pressure that you see under this condition is entirely dependent upon the ambient temperature and nothing else.
