Refrigerant Pressure Sensor / Switch: Testing and Inspection
A scan tool displays A/C refrigerant pressure in psi. The sensors range and corresponding display should be in the range 0 to 450 psi. A sensor or circuit
problem should set DTC P0530. A poor ground at the sensor will result in a fixed high pressure value on the scan tool display.
