Hi there. Has the system been charged recently? If so, there could be too much refrigerant in the system causing the pressure valve to vent the excess pressure; the high pressure sensor is there to prevent catastrophic system failure and prevents the compressor from engaging if it detects pressures that are too high. If it has not been charged recently, there could be a leak on one side of the system. I strongly suggest having a qualified technician, such as one from YourMechanic, perform an AC inspection so you can avoid any unnecessary part replacements.
