P0530. Pertains to A/C Refrigerant Pressure Sensor Circuit its located at the L/side of the engine compartment on the Accumulator.
Have you check all the fuses that's involved in the AC circuit to include the AC clutch relay
Check your high side pressure
If there's a problem with the high side pressure the PCM will not engage the compressor thru the AC pressure sensor same goes with the high pressure cut off switch.
Recheck your pressures
Hope this helps
